- WHO names omicron a ‘variant of concern.’ The World Health Organization (WHO) has identified a new variant of the coronavirus that’s causing concern, called omicron. Health officials say the variant, first identified in South Africa, has “several mutations that may have an impact on how it behaves,” although it’s not yet clear whether the variant spreads easier than delta or causes more severe disease than other versions of the virus. It’s also unclear if omicron poses a threat to the effectiveness of the vaccines. WHO says studies are underway to shed light on these questions. The Centers for Disease Control and Prevention (CDC) says health officials are monitoring the situation, and that no cases caused by omicron have been detected in the U.S. to date. In the meantime, the agency recommends vaccines, masking in public, frequent hand washing and physical distancing to curb the spread of COVID.
- CDC says all adults may get a booster. CDC Director Rochelle Walensky decided on Nov. 19 that anyone over age 18 can get a COVID-19 booster shot. The recommendation comes just hours after the U.S. Food and Drug Administration (FDA) authorized Pfizer and Moderna boosters for all adults at least six months after the first two doses. Boosters from Johnson & Johnson were previously authorized for people 18-plus, two months after the single-shot vaccine. CDC's Advisory Committee on Immunization Practices met after the FDA announcement and unanimously voted to allow all adults to get a booster. Then the committee made another unanimous recommendation to Walensky: that all Americans over age 50 should get the booster shot. Committee members suggested that since Pfizer and Moderna boosters were already recommended for people age 50 to 64 with an underlying condition and that since the majority of people in that age group have such a condition, it would be simpler and more equitable to say that everyone in that age group should get a booster. While the Pfizer booster will be the same strength dose as people got in their first two shots, the Moderna dosage will be half of the one given in the initial vaccine course. The FDA and CDC had already recommended Pfizer and Moderna boosters for adults age 65 and older, younger people with underlying conditions that put them at severe risk for the illness, people with compromised immune systems, those living in long-term care facilities and those who work in jobs that put them at high risk of getting the virus.
- Pfizer asks FDA to authorize its pill to treat COVID. Drugmaker Pfizer has asked the FDA to authorize its experimental pill to treat COVID-19, just as cases of the illness start to climb back up after a recent decline. Pfizer’s pill, called Paxlovid, was shown in clinical trials to reduce risk of COVID-19-related hospitalizations and deaths by 89 percent in high-risk adults, the company said in a news release. Merck and Ridgeback Biotherapeutics have also developed an antiviral pill, called molnupiravir, to treat COVID and are seeking FDA authorization. The FDA’s advisory panel is scheduled to meet and review Merck’s data on Nov. 30. If cleared, these pills would be the first to treat COVID-19; other FDA-approved or authorized treatments require an injection or infusion.
- CDC updates international travel advice. The list of countries Americans are advised to avoid due to COVID-19 concerns is growing. The CDC has added Hungary, Iceland and the Czech Republic to its list of countries to avoid, even for those who are vaccinated. Several other European countries including the United Kingdom, Ireland and Switzerland also share this “level four” warning. The U.S. recently updated its travel guidelines, requiring vaccines for international travelers and lifting a travel ban that had been in place for more than 30 countries. Accepted vaccines for people coming into the U.S. include those approved or authorized by the FDA and the World Health Organization (WHO). Proof of a negative COVID-19 test is also required for all travelers boarding a flight into the U.S. Land borders with Mexico and Canada have also reopened to fully vaccinated travelers. For more information on travel requirements and exceptions, visit the CDC’s website.
- CDC recommends COVID vaccine for children ages 5 to 11. CDC Director Rochelle Walensky has endorsed a recommendation from the Advisory Committee on Immunization Practices to allow children ages 5 to 11 get vaccinated against COVID-19 with Pfizer-BioNTech’s product, which was authorized by the FDA on Oct. 29. This means that health care providers and pharmacists can start administering the vaccine to the newly eligible population — an estimated 28 million kids. Pfizer’s vaccine for 5- to 11-year-olds is a two-shot regimen that is one-third the dose given to individuals age 12 and up. COVID vaccines for children under 5 are still being studied. Meanwhile, vaccine-maker Moderna has requested FDA authorization for its vaccine for 12- to 17-year-olds; the FDA recently told the company it needs more time — probably until January — to review the data. While children tend to fare better than adults when it comes to COVID-19, they are not immune to the disease. During a six-week period from late June to mid-August, COVID-19 hospitalizations among children and adolescents increased fivefold, according to CDC data.
- Vaccines offer greater protection against COVID than previous infection. A new report from the CDC found that unvaccinated individuals were 5.49 times as likely to test positive for a coronavirus infection as those who had been vaccinated within the past three to six months — even if they recently had COVID-19. The study looked at more than 7,000 people across 9 states who were hospitalized with COVID-like illness. "We now have additional evidence that reaffirms the importance of COVID-19 vaccines, even if you have had prior infection," CDC Director Rochelle Walensky said in a statement. "This study adds more to the body of knowledge demonstrating the protection of vaccines against severe disease from COVID-19."
- Fourth shot possible for immunocompromised. The CDC says people over age 18 who are "moderately to severely immunocompromised" and have already gotten a third dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine may get a fourth shot of either of those vaccines or the Johnson & Johnson product. The agency says these fourth shots can be administered at least six months after their third Pfizer or Moderna shot — February 2022 at the earliest. CDC considers this fourth shot a booster and those getting this additional shot will get a dose that is half the volume of the first shots.
Answers to the most frequently asked questions about COVID-19.
How can you catch COVID-19?
COVID-19 is the name of the disease caused by a virus, SARS-CoV-2 (the new coronavirus). It’s spread in three main ways, according to the Centers for Disease Control and Prevention (CDC). You can catch COVID-19 by breathing in air if you are close to an infected person who is exhaling small droplets and particles that contain the virus. You can also get it if those small droplets and particles land in your eyes, nose or mouth (likely through coughs or sneezes), or if you have virus particles on your hands and then touch your eyes, nose or mouth.
Who is at risk for COVID-19?
Anyone can get COVID-19, but some people are more at risk for what experts call “severe disease,” at which time hospitalization or intensive care may be required. Older adults are more likely than younger, healthier people to experience serious illness from COVID-19. In fact, 95 percent of COVID-19 deaths in the U.S. have occurred among people 50 or older — and the risk increases with age.
Adults of any age with an underlying medical condition are also at increased risk for complications from a coronavirus infection, including people with:
- Chronic kidney disease
- Chronic lung diseases, including COPD (chronic obstructive pulmonary disease), asthma (moderate to severe), interstitial lung disease, cystic fibrosis and pulmonary hypertension
- Dementia or other neurological conditions
- Diabetes (type 1 or type 2)
- Down syndrome
- Heart conditions (such as heart failure, coronary artery disease, cardiomyopathies or hypertension)
- HIV infection
- Immunocompromised state (weakened immune system)
- Liver disease
- Mental health conditions, including depression and schizophrenia spectrum disorders
- Overweight and obesity (defined as a body mass index of 25 or greater)
- Sickle cell disease or thalassemia
- Smoking, current or former
- Solid organ or blood stem cell transplant (includes bone marrow transplants)
- Stroke or cerebrovascular disease, which affects blood flow to the brain
- Substance use disorders (such as alcohol, opioid or cocaine use disorder)

What can you do to reduce your risk?
Get vaccinated. The U.S. Food and Drug Administration (FDA) has officially approved one COVID-19 vaccine — a two-shot series from Pfizer-BioNTech — and has issued emergency use authorizations (EUA) for two other COVID-19 vaccines developed by Moderna and Johnson & Johnson (J&J). Full approval for these vaccines may be forthcoming.
All three vaccines are safe and effective at preventing hospitalization and death from COVID-19. Health officials are encouraging everyone 12 and older to get vaccinated (shots for younger populations are still being evaluated), including people who have had COVID-19 in the past. Many older adults are also eligible for booster shots to ramp up their protection against COVID.
Other ways to lower the likelihood of getting sick from COVID-19: Wear a face mask in public indoor settings; avoid crowds and poorly ventilated spaces; put at least 6 feet between yourself and others not in your household; and wash your hands often.
Do the vaccines have side effects?
It’s common to experience mild to moderate side effects after getting vaccinated, such as soreness in the arm, headache, fatigue, muscle and joint pain, nausea, fever or chills — but these are temporary “and normal signs that your body is building protection,” the CDC says.
To date, no long-term side effects have been detected.
A small number of vaccine recipients have experienced adverse reactions. These serious events after COVID-19 vaccination “are rare but may occur,” the CDC says. Anaphylaxis after COVID-19 vaccination has occurred in approximately 2 to 5 people per million vaccinated in the U.S., and 46 cases of a clotting disorder following the J&J vaccine have been recorded, according to the CDC. Health officials are also monitoring reports of Guillain-Barré Syndrome in people who have received the J&J shot, and myocarditis or pericarditis in some younger adults after vaccination.
Can you get COVID-19 even if you’re fully vaccinated?
The COVID-19 vaccines are effective at preventing infection and serious illness, the CDC says. In fact, studies show fully vaccinated people are eight times less likely to be infected and 25 times less likely to experience hospitalization or death.
However, the vaccines are not 100 percent effective, so it is still possible for some fully vaccinated individuals to get COVID-19. This is called a “breakthrough infection.”
Fully vaccinated people with breakthrough infections are less likely to develop serious illness from COVID-19 than unvaccinated people, the CDC says, but they can still be contagious and spread the virus to others. This is why health officials recommend that everyone, regardless of vaccination status, wear a face mask in public indoor settings — especially in areas where virus transmission levels are high or substantial. This can help prevent people with asymptomatic or mild illness from unknowingly spreading the virus to others.
It’s difficult to estimate how many people have asymptomatic or mild breakthrough infections. Severe breakthrough infections, however, are tracked and are rare. As of Sept. 7, about 0.008 percent of the 176 million fully vaccinated Americans have been hospitalized with COVID-19 or have died from the disease.
What are the symptoms of COVID-19?
People with COVID-19 have reported a wide range of symptoms that typically appear two to 14 days after exposure to the virus, including:
- Fever or chills
- Shortness of breath or difficulty breathing
- Muscle or body aches
- New loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
The CDC acknowledges this list is not exhaustive, and some more unusual symptoms have been noted throughout the pandemic — from cognitive complications to skin rashes.
A COVID-19 test can help you determine if you have an infection. You can also check the CDC’s interactive guide for advice on appropriate medical care.
Most people with COVID-19 can recover at home. However, if you develop emergency warning signs — pain or pressure in the chest; new disorientation or confusion; pale, gray or blue-colored skin, lips or nail beds; difficulty breathing; or an inability to wake or stay awake — get medical attention immediately.
What should I know about testing?
The CDC says you should consider getting a COVID-19 test if:
- You have symptoms of COVID-19.
- You have had close contact with someone with confirmed COVID-19.
- You are unvaccinated and have taken part in an activity that puts you at higher risk for COVID-19, such as traveling or attending a large event.
- You have been asked to get tested by a health care provider or state or local health department.
Your health care provider should be able to administer a COVID-19 test. You can also contact your local health department to find out about testing locations. Many pharmacies are also offering on-site testing.
Another option: The FDA has authorized a handful of over-the-counter COVID-19 tests that you can take at home. These so-called rapid antigen tests require a nasal swab and can deliver results in about 15 minutes. Many major retailers sell these tests. Learn more about them here.
Are there treatments?
So far, the FDA has approved just one treatment for COVID-19 — the antiviral drug remdesivir, which is for people hospitalized with COVID-19. A few other therapies have EUAs from the FDA, including monoclonal antibody treatments, which help to mimic the body’s immune system and fight off a viral infection. These are often administered to people who have COVID-19 and are at high risk of the illness progressing to severe disease.
The World Health Organization (WHO) in 2020 issued guidelines that strongly recommend the use of dexamethasone (along with other inexpensive and common corticosteroids such as hydrocortisone) for the treatment of patients “with severe and critical COVID-19.” Clinical trials found that corticosteroids cut the risk of death in patients hospitalized with the disease.
Convalescent plasma has also received an EUA from the FDA. Blood plasma donated by individuals who have recovered from a coronavirus infection can contain antibodies that may speed recovery when administered to patients hospitalized with COVID-19. However, the NIH COVID-19 Treatment Guidelines find there is not enough evidence to recommend these treatments at the present time, according to the CDC.
What about travel during the pandemic?
Before you make travel plans, be sure to double-check any rules pertaining to your destination and mode of transportation. Many states, cities and countries have travel restrictions or guidelines in place that could affect your trip. AARP has a list of coronavirus restrictions in every state. Plus, the CDC has country-specific travel recommendations based on COVID-19 risk levels.
The CDC says both vaccinated and unvaccinated travelers should still follow these recommendations for traveling safely:
- Wear a mask over your nose and mouth. Masks are required on planes, buses, trains and other forms of public transportation, and also in U.S. transportation hubs such as airports and stations.
- Keep a safe distance from others and avoid crowds.
- Wash your hands often or use hand sanitizer.
Fully vaccinated travelers are “less likely to get and spread COVID-19” health officials say, but they should still be on alert. They can leave the country without getting a COVID-19 test unless their destination requires it, and they do not need to self-quarantine after returning to the U.S. unless it’s required by a local jurisdiction.
However, vaccinated people are still required to have a negative COVID-19 test result before they board an international flight in order to return to the U.S., the CDC says, and they should take a COVID-19 test three to five days after returning. People are fully vaccinated two weeks after they receive their second dose of the Pfizer or Moderna vaccines or the single-dose Johnson & Johnson vaccine. If you are unvaccinated: The CDC recommends delaying travel until you are fully vaccinated because travel increases your chance of getting and spreading COVID-19. Testing can help you travel more safely, the CDC says. The CDC recommends getting tested with a viral test one to three days before your trip. Keep a copy of your test results with you during travel; you may be asked for them.
International travel is strongly discouraged for unvaccinated individuals. Those who must travel should have a negative COVID-19 viral test result no more than three days before leaving the country, and they are required to have a negative COVID-19 viral test result no more than three days before returning to the U.S.
Testing and quarantining are also advised upon return. AARP has information about specific travel advisories, and airline change fees, as well as tips on how to stay safe when you travel.
What are the variants?
Public health officials have identified several new strains of the coronavirus, some of which are more contagious and may cause more severe illness.
So far, the available vaccines still provide a high level of protection against the circulating variants, including against delta — the dominant variant in the U.S. that is responsible for about 99 percent of new COVID-19 cases.
However, the more the virus spreads, the more opportunities it has to change. And it may be that one day, a new variant pops up with the ability to evade the current tools we have to fight it. The best way to prevent this scenario, health experts say, is to get vaccinated and slow the spread of SARS-CoV-2.
What is long COVID?
Many COVID-19 survivors battle lingering symptoms for weeks or months after infection, even if the initial infection was mild or asymptomatic. Sometimes called “long-haulers,” they suffer from dizziness, insomnia, confusion, a racing heart or a host of other lasting effects that keep them from getting back to their normal lives. A recent report published by the CDC found that as many as one-third of people with COVID-19 had lingering symptoms two months after a positive test result.
Experts encourage COVID-19 patients experiencing long COVID to seek care from a medical provider. Several U.S. hospitals and research centers have set up special clinics and rehabilitation services for survivors.
