Background

Residents in nursing homes are at increased risk of becoming colonized and developing infection with MDROs [2]. As described further in Consideration for the Use of Enhanced Barrier Precautions in Skilled Nursing Facilities [PDF – 9 pages], more than 50% of nursing home residents may be colonized with an MDRO, nursing homes have been the setting for MDRO outbreaks, and when these MDROs result in resident infections, limited treatment options are available [1-9]. Implementation of Contact Precautions, as described in the CDC Guideline for Isolation Precautions, is perceived to create challenges for nursing homes trying to balance the use of PPE and room restriction to prevent MDRO transmission with residents’ quality of life. Thus, many nursing homes only implement Contact Precautions when residents are infected with an MDRO and on treatment.

Focusing only on residents with active infection fails to address the continued risk of transmission from residents with MDRO colonization, who by definition have no symptoms of illness. MDRO colonization may persist for long periods of time (e.g., months) [10] which contributes to the silent spread of MDROs.

With the need for an effective response to the detection of serious antibiotic resistance threats, there is growing evidence that the traditional implementation of Contact Precautions in nursing homes is not implementable for most residents for prevention of MDRO transmission.

This document is intended to provide guidance for PPE use and room restriction in nursing homes for preventing transmission of MDROs, including as part of a public health response. For the purposes of this guidance, the MDROs for which the use of EBP applies are based on local epidemiology. At a minimum, they should include resistant organisms targeted by CDC but can also include other epidemiologically important MDROs [9, 10].

Examples of MDROs Targeted by CDC include:

• Pan-resistant organisms,
• Carbapenemase-producing carbapenem-resistant Enterobacterales,
• Carbapenemase-producing carbapenem-resistant Pseudomonas spp.,
• Carbapenemase-producing carbapenem-resistant  Acinetobacter baumannii, and
• Candida auris

Additional epidemiologically important MDROs may include, but are not limited to:

• Methicillin-resistant Staphylococcus aureus (MRSA),
• ESBL-producing Enterobacterales,
• Vancomycin-resistant Enterococci (VRE),
• Multidrug-resistant Pseudomonas aeruginosa,
• Drug-resistant Streptococcus pneumoniae

This document is not intended for use in acute care or long-term acute care hospitals and does not replace existing guidance regarding use of Contact Precautions for other pathogens (e.g., Clostridioides difficile, norovirus) in nursing homes.

Description of Precautions

Standard Precautions are a group of infection prevention practices that apply to the care of all residents, regardless of suspected or confirmed infection or colonization status. They are based on the principle that all blood, body fluids, secretions, and excretions (except sweat) may contain transmissible infectious agents. Proper selection and use of PPE, such as gowns and gloves, is one component of Standard Precautions, along with hand hygiene, safe injection practices, respiratory hygiene and cough etiquette, environmental cleaning and disinfection, and reprocessing of reusable medical equipment. Use of PPE is based on the staff interaction with residents and the potential for exposure to blood, body fluids, or pathogens (e.g., gloves are worn when contact with blood, body fluids, mucous membranes, non-intact skin, or potentially contaminated surfaces or equipment are anticipated). More detail about Standard Precautions is available as part of the Core Infection Prevention and Control Practices for Safe Healthcare Delivery in all Settings.

Contact Precautions are one type of Transmission-Based Precaution that are used when pathogen transmission is not completely interrupted by Standard Precautions alone. Contact Precautions are intended to prevent transmission of infectious agents, like MDROs, that are spread by direct or indirect contact with the resident or the resident’s environment.

Contact Precautions require the use of gown and gloves on every entry into a resident’s room. The resident is given dedicated equipment (e.g., stethoscope and blood pressure cuff) and is placed into a private room. When private rooms are not available, some residents (e.g., residents with the same pathogen) may be cohorted, or grouped together. Residents on Contact Precautions should be restricted to their rooms except for medically necessary care and restricted from participation in group activities.

Because Contact Precautions require room restriction, they are generally intended to be time limited and, when implemented, should include a plan for discontinuation or de-escalation.

More detail about Transmission-Based Precautions, including descriptions of Droplet Precautions and Airborne Precautions are available in the CDC Guideline for Isolation Precautions. In addition, other infections (e.g. norovirus, C. difficile, and scabies) and conditions for which Contact Precautions are indicated are summarized in Appendix A – Type and Duration of Precautions Recommended for Selected Infections and Conditions of the guideline.

Enhanced Barrier Precautions expand the use of PPE and refer to the use of gown and gloves during high-contact resident care activities that provide opportunities for transfer of MDROs to staff hands and clothing [11-15]. MDROs may be indirectly transferred from resident-to-resident during these high-contact care activities. Nursing home residents with wounds and indwelling medical devices are at especially high risk of both acquisition of and colonization with MDROs [3,5,6]. The use of gown and gloves for high-contact resident care activities is indicated, when Contact Precautions do not otherwise apply, for nursing home residents with wounds and/or indwelling medical devices regardless of MDRO colonization as well as for residents with MDRO infection or colonization.

Examples of high-contact resident care activities requiring gown and glove use for Enhanced Barrier Precautions include:

• Dressing
• Bathing/showering
• Transferring
• Providing hygiene
• Changing linens
• Changing briefs or assisting with toileting
• Device care or use: central line, urinary catheter, feeding tube, tracheostomy/ventilator
• Wound care: any skin opening requiring a dressing

In general, gown and gloves would not be required for resident care activities other than those listed above, unless otherwise necessary for adherence to Standard Precautions. Residents are not restricted to their rooms or limited from participation in group activities. Because Enhanced Barrier Precautions do not impose the same activity and room placement restrictions as Contact Precautions, they are intended to be in place for the duration of a resident’s stay in the facility or until resolution of the wound or discontinuation of the indwelling medical device that placed them at higher risk.

Implementation

When implementing Contact Precautions or Enhanced Barrier Precautions, it is critical to ensure that staff have awareness of the facility’s expectations about hand hygiene and gown/glove use, initial and refresher training, and access to appropriate supplies. To accomplish this:

• Post clear signage on the door or wall outside of the resident room indicating the type of Precautions and required PPE (e.g., gown and gloves)
  • For Enhanced Barrier Precautions, signage should also clearly indicate the high-contact resident care activities that require the use of gown and gloves
• Make PPE, including gowns and gloves, available immediately outside of the resident room
• Ensure access to alcohol-based hand rub in every resident room (ideally both inside and outside of the room)
• Position a trash can inside the resident room and near the exit for discarding PPE after removal, prior to exit of the room or before providing care for another resident in the same room
• Incorporate periodic monitoring and assessment of adherence to determine the need for additional training and education
• Provide education to residents and visitors

Note: Prevention of MDRO transmission in nursing homes requires more than just proper use of PPE and room restriction. Guidance on implementing other recommended infection prevention practices (e.g., hand hygiene, environmental cleaning, proper handling of wounds, indwelling medical devices, and resident care equipment) are available in CDC’s free online course — The Nursing Home Infection Preventionist Training. Nursing homes are encouraged to have staff review relevant modules and to use the resources provided in the training (e.g., policy and procedure templates, checklists) to assess and improve practices in their facility.

Each year, millions of older people—those 65 and older—fall. In fact, more than one out of four older people falls each year, but less than half tell their doctor. Falling once doubles your chances of falling again.

Falls Are Serious and Costly

• One out of five falls causes a serious injury such as broken bones or a head injury^,4,5
• Each year, 3 million older people are treated in emergency departments for fall injuries.⁶
• Over 800,000 patients a year are hospitalized because of a fall injury, most often because of a head injury or hip fracture.⁶
• Each year at least 300,000 older people are hospitalized for hip fractures.⁷
• More than 95% of hip fractures are caused by falling,⁸ usually by falling sideways.⁹
• Falls are the most common cause of traumatic brain injuries (TBI).¹⁰
• In 2015, the total medical costs for falls totaled more than $50 billion.¹¹ Medicare and Medicaid shouldered 75% of these costs.

What Can Happen After a Fall?

Many falls do not cause injuries. But one out of five falls does cause a serious injury such as a broken bone or a head injury.^4,5 These injuries can make it hard for a person to get around, do everyday activities, or live on their own.

• Falls can cause broken bones, like wrist, arm, ankle, and hip fractures.
• Falls can cause head injuries. These can be very serious, especially if the person is taking certain medicines (like blood thinners). An older person who falls and hits their head should see their doctor right away to make sure they don’t have a brain injury.
• Many people who fall, even if they’re not injured, become afraid of falling. This fear may cause a person to cut down on their everyday activities. When a person is less active, they become weaker and this increases their chances of falling.¹²

What Conditions Make You More Likely to Fall?

Research has identified many conditions that contribute to falling. These are called risk factors. Many risk factors can be changed or modified to help prevent falls. They include:

• Lower body weakness
• Vitamin D deficiency (that is, not enough vitamin D in your system)
• Difficulties with walking and balance
• Use of medicines, such as tranquilizers, sedatives, or antidepressants. Even some over-the-counter medicines can affect balance and how steady you are on your feet.
• Vision problems
• Foot pain or poor footwear
• Home hazards or dangers such as
  • broken or uneven steps, and
  • throw rugs or clutter that can be tripped over.

Most falls are caused by a combination of risk factors. The more risk factors a person has, the greater their chances of falling.

Healthcare providers can help cut down a person’s risk by reducing the fall risk factors listed above. To learn more, please visit https://www.cdc.gov/falls/facts.html.

In 2020, there were almost 48 million licensed drivers ages 65 and older in the United States. This is a 68% increase since 2000. Driving helps older adults stay mobile and independent. But the risk of being injured or killed in a traffic crash increases as people age. Thankfully, older adults can take steps to stay safer on the roads.

Thousands of older adults are injured or killed in the United States every year in traffic crashes.

In 2020, about 7,500 older adults were killed in traffic crashes, and almost 200,000 were treated in emergency departments for crash injuries. This means that each day, 20 older adults are killed and almost 540 are injured in crashes.

Age, gender, and age-related changes are major risk factors

• Drivers aged 70+ have higher crash death rates per 1,000 crashes than middle-aged drivers (aged 35-54). Higher crash death rates among this age group are primarily due to increased vulnerability to injury in a crash.
• Across all age groups, males have substantially higher crash death rates than females.
• Age-related changes in vision, physical functioning, and the ability to reason and remember, as well as some diseases and medications, might affect some older adults’ driving abilities.

Key steps to staying safe on the roads

• The good news is that older adults are more likely to have safer driving behaviors than other age groups.
• Taking these key steps can help adults of all ages, including older adults, stay safe on the road:
• Always wear a seat belt as a driver or passenger
  Seat belt use is one of the most effective ways to save lives and reduce injuries in crashes.⁶
• Drive when conditions are safest
  Drive during daylight and in good weather. Conditions such as poor weather⁷ and driving at night⁸ increase the likelihood of crash injuries and deaths.
• Don’t drink and drive
  Drinking and driving increases the risk of being in a crash because alcohol reduces coordination and impairs judgment.

Additional steps to stay safe on the road

• Use CDC’s MyMobility Plan, a plan to stay mobile and independent as you age.
• Follow a regular activity program to increase strength and flexibility.
• Ask your doctor or pharmacist to review medicines—both prescription and over-the counter—to reduce side effects and interactions. Read the Are Your Medicines Increasing Your Risk of a Fall or a Car Crash fact sheet to learn more.
• Have your eyes checked by an eye doctor at least once a year. Wear glasses and corrective lenses as required.
• Plan your route before you drive.
• Find the safest route with well-lit streets, intersections with left-turn signals, and easy parking.
• Leave a large following distance between your car and the car in front of you.
• Avoid distractions in your car, such as listening to a loud radio, talking or texting on your phone, and eating.
• Consider potential alternatives to driving, such as riding with a friend, using ride share services, or taking public transit.

You go to the hospital to get well, right? Of course, but did you know that you can get infections in the hospital while you are being treated for something else?

Time in the hospital can put you at risk for a healthcare-associated infection (HAI), such as a blood, surgical site, or urinary tract infection.

Every day, patients get infections in healthcare facilities while they are being treated for something else. These infections can have devastating emotional, financial, and medical effects. Worst of all, they can be deadly.

Healthcare procedures can leave you vulnerable to germs that cause HAIs. These germs can be spread in healthcare settings from patient to patient on unclean hands of healthcare personnel or through the improper use or reuse of equipment.

These infections are not limited to hospitals. For example, in the past 10 years alone, there have been more than 30 outbreaks of hepatitis B and hepatitis C in non-hospital healthcare settings such as

• outpatient clinics,
• dialysis centers, and
• long-term care facilities.

5 Tips for Patients [Video – 2:32]

Protect yourself and your family from harmful germs that can cause infections

• Keep your hands clean. Regular hand cleaning is one of the best ways to remove germs, avoid getting sick, and prevent spreading germs.
• Take antibiotics only when your provider thinks you need them. Ask if your antibiotic is necessary. If you take antibiotics when you don’t need them, you’re only exposing yourself to unnecessary risk of side effects and potentially serious infections in the future. If you do need antibiotics, take them exactly as they’re prescribed.
• Watch for signs of infection and its complications, like sepsis. Get care right away—don’t delay.
  • Tell your doctor if you think you have an infection, or if your infection is not getting better or is getting worse.
• Watch out for life-threatening diarrhea caused by C. difficile. If you have been taking an antibiotic, tell your doctor if you have 3 or more diarrhea episodes in 24 hours.
• Get vaccinated against flu and other infections to avoid complications.

Sepsis is the body’s extreme response to an infection. It is a life-threatening medical emergency. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death. Learn more about sepsis.

Be a safe patient in the hospital

• Tell your doctors if you have been hospitalized in another facility, have recently received health care outside of the United States, or have recently had an infection.
• Ask your healthcare provider what they and the facility will do to protect you and your family from an antibiotic-resistant infection.
  • If you have a catheter, ask daily when it can be removed.
  • If you are having surgery, ask your doctor how they prevent infections. Also, ask how you can prepare for surgery to reduce your infection risk.
• Keep your hands clean. Make sure everyone cleans their hands before touching you. Remind healthcare personnel and your visitors to clean their hands.
• Let your doctors check you for resistant germs if needed. Hospitals need to screen patients if they’re exposed, and this helps protect you and those around you.
• Understand that if you have a resistant bacteria, healthcare providers may use gowns and gloves when caring for you.
• Allow people to clean your room while you’re in the hospital, even when it feels inconvenient for you.
  • Environmental services workers are the people who clean patient rooms in the hospital, and they are important members of the healthcare team.
  • Allowing them to clean and disinfect your room helps keep you safe by reducing your risk of developing an infection—don’t say, “come back later.”

Nicholasville Nursing and Rehabilitation is excited to share resident Kathy Darby’s Success Story!

Ms. Kathy Darby is a long-term care resident who came to Nicholasville Nursing and Rehabilitation in December of 2020 due to no longer being able to live alone in the community. She can no longer walk and uses a power wheelchair for all mobility. She recently experienced a decline in her strength and trunk control. Our Physical Therapy team evaluated her to address her deficits and regain her independence sitting upright in her wheelchair for meals and activities. She loves to play basketball on the Restore program and often requests to play, as she feels that it is helping her regain her overall sitting balance. She is progressing toward her goals of increasing her overall balance for sitting on the edge of the bed, completing more daily tasks independently, and sitting upright in her wheelchair for meals and activities.
Way to go, Kathy! Keep up the excellent work.

Dementia: Not an Inevitable Part of Aging

A recent survey revealed that nearly half of adults aged 40 years and older think they will likely develop dementia, such as Alzheimer’s disease.¹

The truth is dementia is not a normal or inevitable part of typical brain aging. It is also important to remember that as we get older, it is common to experience some cognitive decline with typical brain aging, such as subtle changes in memory, thinking, and  reasoning. For example, you might not immediately remember where you left your car keys, but you can find them when retracing your steps, or you can’t think of the name of a person you just met; however, you remember meeting them. These subtle changes can be frustrating and should not be bad enough to affect your daily life.

Modifiable Risk Factors and Alzheimer’s Disease and Related Dementias

Modifiable risk factors are the lifestyle and behaviors that can reduce or increase a person’s chances of developing a disease. For example, there are modifiable risk factors that could reduce your risk of Alzheimer’s disease and related dementias (ADRD), slow its progression, or increase your risk of ADRD. Most modifiable risk factors for ADRD are related to cardiovascular disease and other chronic health conditions. They include hypertension, not getting enough physical exercise, obesity, diabetes, depression, smoking, hearing loss, and binge drinking. Maintaining a healthy lifestyle and managing related chronic conditions is good for your overall physical health, facilitates and improves brain health, and may help decrease the risk of dementia or slow its progression.

Common Risk Factors Among Adults 45 Years and Older

A new CDC study examined how common these eight risk factors (hypertension, not getting enough physical exercise, obesity, diabetes, depression, smoking, hearing loss, and binge drinking) were among adults 45 years and older: ² 

• Nearly 50% had high blood pressure or did not meet the aerobic physical activity guideline.
• Adults with cognitive decline were more likely to report at least 4 factors (34%) than those without cognitive decline (13%).
• 34% of adults who reported cognitive decline—worsening confusion or memory loss in the previous year—had at least 4 risk factors compared with 13.1% of those without cognitive decline.
• 9% of adults with no risk factors reported cognitive decline while 25% of those with at least 4 risk factors reported cognitive decline.
• Several modifiable risk factors were more common among African American, Hispanic, and American Indian or Alaska Native populations than other races and ethnicities.

Older African Americans have twice the incidence and prevalence of ADRD and higher burdens of chronic disease, like hypertension, than non-Hispanic White Americans.³

Ways to Improve Your Brain Health

There is encouraging scientific news despite these risk factors: nearly 40% of all ADRD may be prevented or delayed.⁴ Since ADRD takes years to develop, there are opportunities to develop and maintain healthy lifestyle habits that could reduce your risk of ADRD or slow its progression. It is never too late to break old habits and start new ones.

This healthy lifestyle habits list consists of some things you can do and some things you should try to limit or avoid.

Things You Can Do: 

• Get Active and Maintain a Healthy Weight—Regular physical activity is important for good health and combined with a healthy diet can lead to a healthy weight.

• Manage Blood Sugar—Learn how to manage your blood sugar if you have diabetes.
• Prevent and Manage High Blood Pressure—Tens of millions of adults in the United States have high blood pressure, and many do not have it under control. Learn the facts.
• Prevent and Correct Hearing Loss—Make sure to talk to a hearing care professional to treat and manage hearing loss.
• Find Support—Depression is not just having “the blues” or the emotions we feel when grieving the loss of a loved one. It is a medical condition that can be treatable.

Things You Should Try to Limit or Avoid:

• Binge Drinking—If you drink, do so in moderation. Learn about alcohol use and your health.
• Smoking—Quitting smoking improves your health and reduces your risk of heart disease, cancer, lung disease, and other smoking-related illnesses.

There are four types of influenza viruses: A, B, C, and D. Influenza A and B viruses cause seasonal epidemics of disease in people (known as flu season) almost every winter in the United States. Influenza A viruses are the only influenza viruses known to cause flu pandemics (i.e., global epidemics of flu disease). A pandemic can occur when a new and different influenza A virus emerges that infects people, has the ability to spread efficiently among people, and against which people have little or no immunity. Influenza C virus infections generally cause mild illness and are not thought to cause human epidemics. Influenza D viruses primarily affect cattle and are not known to infect or cause illness in people.

Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N). There are 18 different hemagglutinin subtypes and 11 different neuraminidase subtypes (H1 through H18 and N1 through N11, respectively). While more than 130 influenza A subtype combinations have been identified in nature, primarily from wild birds, there are potentially many more influenza A subtype combinations given the propensity for virus “reassortment.” Reassortment is a process by which influenza viruses swap gene segments. Reassortment can occur when two influenza viruses infect a host at the same time and swap genetic information. Current subtypes of influenza A viruses that routinely circulate in people include A(H1N1) and A(H3N2). Influenza A subtypes can be further broken down into different genetic “clades” and “sub-clades.” See the “Influenza Viruses” graphic below for a visual depiction of these classifications.

This graphic shows the two types of influenza viruses (A and B) that cause most human illness and that are responsible for flu seasons each year. Influenza A viruses are further classified into subtypes, while influenza B viruses are further classified into two lineages: B/Yamagata and B/Victoria. Both influenza A and B viruses can be further classified into clades and sub-clades (which are sometimes called groups and sub-groups.) Note that this graphic is an example, and currently circulating influenza clades and subclades may differ from those presented here.

Influenza Vaccine Viruses

Current seasonal flu vaccines are formulated to protect against influenza viruses known to cause epidemics, including: one influenza A(H1N1) virus, one influenza A(H3N2) virus, one influenza B/Victoria lineage virus, and one influenza B/Yamagata lineage virus. Getting a flu vaccine can protect against these viruses as well as additional flu viruses that are antigenically similar to the viruses used to make the vaccine. Information about this season’s vaccine can be found at Preventing Seasonal Flu with Vaccination. Seasonal flu vaccines do not protect against influenza C or D viruses or against zoonotic (animal-origin) flu viruses that can cause human infections, such as variant or avian (bird) flu viruses. In addition, flu vaccines will NOT protect against infection and illness caused by other viruses that also can cause influenza-like symptoms. There are many other viruses besides influenza that can result in influenza-like illness (ILI) that spread during flu season.

Nicholasville Nursing and Rehabilitation is excited to shine the spotlight on resident Larry Singleton’s Success Story!

Mr. Singleton was admitted to Nicholasville Nursing and Rehabilitation for overall weakness and required a feeding tube. His goal was to improve functional independence and be able to return home. He worked hard in Physical, Occupational, and Speech Therapy to target walking, balance, activities of daily living, cognitive function, and swallowing. Larry has excelled in all aspects and demonstrated the functional ability to discharge home safely with minimal assistance! He can now enjoy regular food by mouth and no longer requires his feeding tube. We have enjoyed working with Mr. Singleton and are happy to be part of his healing journey!

Everyone 6 months and older should get a flu vaccine every season with rare exceptions. Vaccination is particularly important for people who are at higher risk of serious complications from influenza. A full listing of people at Higher Risk of Developing Flu-Related Complications is available.

Flu vaccination has important benefits. It can reduce flu illnesses, visits to doctor’s offices, and missed work and school due to flu, as well as make symptoms less severe and reduce flu-related hospitalizations and deaths.

Different flu vaccines are approved for use in different age groups.

• There are several flu shots approved for use in people as young as 6 months old and older, and two are approved only for adults 65 years and older.
• Flu shots also are recommended for pregnant people and people with certain chronic health conditions.
• The nasal spray flu vaccine is approved for use in people 2 years through 49 years of age. People who are pregnant and people with certain medical conditions should not receive the nasal spray flu vaccine.

There are many vaccine options to choose from.

• For people younger than 65 years, CDC does not recommend any one flu vaccine over another.
• For adults 65 years and older, there are three flu vaccines that are preferentially recommended for people 65 years and older. These are Fluzone High-Dose Quadrivalent vaccine, Flublok Quadrivalent recombinant flu vaccine and Fluad Quadrivalent adjuvanted flu vaccine. If none of the three flu vaccines preferentially recommended for people 65 and older is available at the time of administration, people in this age group can get any other age-appropriate flu vaccine instead.

The most important thing is for all people 6 months and older to get a flu vaccine every year.

If you have questions about which flu vaccine to get, talk to your doctor or other health care professional. More information is available at Who Should and Who Should NOT Get a Flu Vaccine.

WHO SHOULD NOT RECEIVE A FLU SHOT:

Different influenza (flu) vaccines are approved for use in people in different age groups. In addition, some vaccines are not recommended for certain groups of people. Factors that can determine a person’s suitability for vaccination, or vaccination with a particular vaccine, include a person’s age, health (current and past) and any allergies to flu vaccine or its components. More information is available at Who Should and Who Should NOT get a Flu Vaccine.

ARE ANY OF THE AVAILABLE FLU VACCINES RECOMMENDED OVER OTHERS?

Yes, for some people. For the 2022-2023 flu season, there are three flu vaccines that are preferentially recommended for people 65 years and older. These are Fluzone High-Dose Quadrivalent vaccine, Flublok Quadrivalent recombinant  flu vaccine and Fluad Quadrivalent adjuvanted flu vaccine. This recommendation was based on a review of available studies which suggests that, in this age group, these vaccines are potentially more effective than standard dose unadjuvanted flu vaccines. There is no preferential recommendation for people younger than 65 years.

WHAT IF A PREFERENTIALLY RECOMMENDED FLU VACCINE IS NOT AVAILABLE?

If none of the three flu vaccines preferentially recommended for people 65 years and older is available at the time of administration, people in this age group should get any other age-appropriate flu vaccine instead.

SPECIAL CONSIDERATION REGARDING EGG ALLERGY

People with egg allergies can receive any licensed, recommended age-appropriate influenza (flu) vaccine (IIV4, RIV4, ccIIV4, or LAIV4) that is otherwise appropriate. People who have a history of severe egg allergy (those who have had any symptom other than hives after exposure to egg) should be vaccinated in a medical setting, supervised by a health care provider who is able to recognize and manage severe allergic reactions. Two completely egg-free flu vaccine options are available: Flublok Quadrivalent recombinant flu vaccine and Flucelvax Quadrivalent cell-based flu shot.

Get vaccinated before flu season starts

It takes about two weeks after vaccination for antibodies that protect against flu to develop in the body.

WHEN SHOULD I GET VACCINATED AGAINST FLU?

For most people who need only one dose of flu vaccine for the season, September and October are generally good times to be vaccinated against flu. Ideally, everyone should be vaccinated by the end of October. Additional considerations concerning the timing of vaccination for certain groups of people include:

• Most adults, especially those 65 years and older, and pregnant people in the first or second trimester should generally not get vaccinated early (in July or August) because protection may decrease over time. However, early vaccination can be considered for any person who is unable to return at a later time to be vaccinated.
• Some children need two doses of flu vaccine. For those children it is recommended to get the first dose as soon as vaccine is available, because the second dose needs to be given at least four weeks after the first. Vaccination during July and August also can be considered for children who need only one dose.
• Vaccination during July and August also can be considered for people who are in the third trimester of pregnancy during those months, because this can help protect their infants for the first few months after birth (when they are too young to be vaccinated).

How do I know if I have the flu?

Your respiratory illness might be influenza (flu) if you have fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and/or fatigue. Some people may have vomiting and diarrhea, though this is more common in children. People may be sick with flu and have respiratory symptoms without a fever. Flu viruses usually cause the most illness during the colder months of the year. However, flu can also occur outside of the typical flu season. In addition, other viruses can also cause respiratory illness similar to flu. So, it is impossible to tell for sure if you have flu based on symptoms alone. If your doctor needs to know for sure whether you are sick with flu, there are laboratory tests that can be done.

What kinds of flu tests are there?

A number of tests are available to detect flu viruses in respiratory specimens. The most common are called “rapid influenza diagnostic tests (RIDTs).” RIDTs work by detecting the parts of the virus (antigens) that stimulate an immune response. These tests can provide results within approximately 10-15 minutes but may not be as accurate as other flu tests. Therefore, you could still have flu, even though your rapid test result is negative. Other flu tests called “rapid molecular assays” detect genetic material of the flu virus. Rapid molecular assays produce results in 15-20 minutes and are more accurate than RIDTs.

In addition to RIDTs and rapid molecular assays, there are several more accurate flu tests available that must be performed in specialized laboratories, such as hospital and public health laboratories. These tests include reverse transcription polymerase chain reaction (RT-PCR), viral culture, and immunofluorescence assays. All of these tests require that a health care provider swipe the inside of your nose or the back of your throat with a swab and then send the swab for testing. Results may take one to several hours.

How well can rapid tests detect flu?

During a flu outbreak, a positive rapid flu test is likely to indicate flu virus infection. However, rapid tests vary in their ability to detect flu viruses, depending on the type of rapid test used, and on the type of flu viruses circulating. Also, rapid tests appear to be better at detecting flu in children than in adults. This variation in ability to detect viruses can result in some people who are infected with flu having a negative rapid test result. This situation is called a false negative test result. Despite a negative rapid test result, your health care provider may diagnose you with flu based on your symptoms and their clinical judgment.

Will my health care provider test me for flu if I have flu-like symptoms?

While your doctor may test you for flu, not everyone who goes to the doctor with flu-like symptoms will be tested. After evaluating you, your doctor may choose to diagnose you with flu without the need for testing based on your symptoms and his or her own clinical judgement.

Please visit diagnosing flu for more information.

Difference Between Flu and COVID-19

Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same. Some PCR tests can differentiate between flu and COVID-19 at the same time. If one of these tests is not available, many testing locations provide flu and COVID-19 tests separately. Talk to a healthcare provider about getting tested for both flu and COVID-19 if you have symptoms.

Can I have flu and COVID-19 at the same time?

Yes. It is possible to have flu as well as other respiratory illnesses including COVID-19 at the same time. Health experts are still studying how common this can be.

Is there a test that can detect both flu and COVID-19?

Yes. There is a test that will check for seasonal flu type A and B viruses and SARS-CoV-2, the virus that causes COVID-19. This test is being used by U.S. public health laboratories for surveillance purposes. Testing for these viruses at the same time will give public health officials important information about how flu and COVID-19 are spreading and what prevention steps should be taken. The test will also help public health laboratories save time and testing materials, and possibly to return test results faster.

The Food and Drug Administration (FDA) has given CDC an Emergency Use Authorization for this new test. Initial test kits were sent to public health laboratories in early August 2020. CDC will continue to manufacture and distribute these kits.

More information for laboratories is available.
