Ending Isolation

Updated Jan. 14, 2022

CDC’s COVID-19 Community Levels recommendations do not apply in healthcare settings, such as hospitals and nursing homes. Instead, healthcare settings should continue to use community transmission rates and continue to follow CDC’s infection prevention and control recommendations for healthcare settings.

This page is for healthcare professionals caring for people in the community setting under isolation with laboratory-confirmed COVID-19. See Quarantine and Isolation for more information for the general population in the community.

These recommendations do not apply to healthcare personnel and do not supersede state, local, tribal, or territorial laws, rules, and regulations. For healthcare settings, please see Managing Healthcare Personnel with SARS-CoV-2 Infection or Exposure to SARS-CoV-2 and Interim Infection Prevention and Control Recommendations for Healthcare Personnel. For more details, including details on certain non-healthcare settings, please review Setting-Specific Guidance.

Summary of Recent Changes

As of January 14, 2022

Updated guidance to reflect new recommendations for isolation for people with COVID-19.

Added new recommendations for duration of isolation for people with COVID-19 who are moderately or severely immunocompromised.

Key Points for Healthcare Professionals

Children and adults with mild, symptomatic COVID-19: Isolation can end at least 5 days after symptom onset and after fever ends for 24 hours (without the use of fever-reducing medication) and symptoms are improving, if these people can continue to properly wear a well-fitted mask around others for 5 more days after the 5-day isolation period. Day 0 is the first day of symptoms.People who are infected but asymptomatic (never develop symptoms): Isolation can end at least 5 days after the first positive test (with day 0 being the date their specimen was collected for the positive test), if these people can continue to wear a properly well-fitted mask around others for 5 more days after the 5-day isolation period. However, if symptoms develop after a positive test, their 5-day isolation period should start over (day 0 changes to the first day of symptoms).People who have moderate COVID-19 illness: Isolate for 10 days.People who are severely ill (i.e., requiring hospitalization, intensive care, or ventilation support): Extending the duration of isolation and precautions to at least 10 days and up to 20 days after symptom onset, and after fever ends (without the use of fever-reducing medication) and symptoms are improving, may be warranted.People who are moderately or severely immunocompromised might have a longer infectious period: Extend isolation to 20 or more days (day 0 is the first day of symptoms or a positive viral test). Use a test-based strategy and consult with an infectious disease specialist to determine the appropriate duration of isolation and precautions.Recovered patients: Patients who have recovered from COVID-19 can continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset. However, replication-competent virus has not been reliably recovered from such patients, and they are not likely infectious.On This Page

Recommendation for Ending Isolation

For people who are mildly ill with a laboratory-confirmed SARS-CoV-2 infection and not moderately or severely immunocompromised:

Isolation can be discontinued at least 5 days after symptom onset (day 1 through day 5 after symptom onset, with day 0 being the first day of symptoms), and after resolution of fever for at least 24 hours (without the use of fever-reducing medications) and with improvement of other symptoms.

Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation​.

These people should continue to properly wear a well-fitted mask around others at home and in public for 5 additional days (day 6 through day 10 after symptom onset) after the 5-day isolation period.

People who cannot properly wear a mask, including children < 2 years of age and people of any age with certain disabilities, should isolate for 10 days. In certain high-risk congregate settings that have high risk of secondary transmission and where it is not feasible to cohort people, CDC recommends a 10-day isolation period for residents.

More details: What We Know About Quarantine and IsolationFor people who test positive, are asymptomatic (never develop symptoms) and not moderately or severely immunocompromised:

Isolation can be discontinued at least 5 days after the first positive viral test (day 0 through day 5, with day 0 being the date their specimen was collected for the positive test).

If you've been exposed to the coronavirus

April 12, 2022

If you've been exposed, are sick, or are caring for someone with COVID-19

If you've been exposed to someone with COVID-19 or begin to experience symptoms of the disease, you may be asked to self-quarantine or self-isolate. What does that entail, and what can you do to prepare yourself for an extended stay at home? How soon after you're infected will you start to be contagious? And what can you do to prevent others in your household from getting sick?

Visit our Coronavirus Resource Center for more information on coronavirus and COVID-19.

Symptoms of COVID-19

What are the symptoms of COVID-19?

Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell. In some people, COVID-19 causes more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia.

People with COVID-19 can also experience neurological symptoms, gastrointestinal (GI) symptoms, or both. These may occur with or without respiratory symptoms.

For example, COVID-19 affects brain function in some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, inability to taste, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.

In addition, some people have gastrointestinal (GI) symptoms, such as loss of appetite, nausea, vomiting, diarrhea, and abdominal pain or discomfort associated with COVID-19.

What should I do if I think I or my child may have a COVID-19 infection?

First, call your doctor or pediatrician for advice.

If you do not have a doctor and you are concerned that you or your child may have COVID-19, contact your local board of health. They can direct you to the best place for testing and treatment in your area. Over-the-counter tests may also be available at your local pharmacy or grocery store.

If you do test positive and either have no symptoms or can recover at home, you will still need to

isolate at home for five days

if you have no symptoms or your symptoms are improving after five days, you can discontinue isolation and leave your home

continue to wear a mask around others for five additional days.

If you have a fever, continue to isolate at home until you no longer have a fever.

If you have a high or very low body temperature, shortness of breath, confusion, or feeling you might pass out, you need to seek immediate medical evaluation. Call the urgent care center or emergency department ahead of time to let the staff know that you are coming, so they can be prepared for your arrival.

What is "Test to Treat"? Could it help me get antiviral treatment for COVID-19?

Test to Treat is a government initiative that makes it faster and easier for people with COVID-19 to obtain treatment. This is important because antiviral treatments for COVID-19 must be started within five days of a positive test or the start of symptoms. With Test to Treat, a person can get tested, get a prescription, and get their prescription filled, all in one place.

Here’s how it works. If you think you may have COVID-19, go to a Test to Treat site to get tested. If you test positive you will meet with a healthcare provider and, if you are eligible, will receive a prescription for antiviral treatment. You can then get your prescription filled at the same site.

A few things to keep in mind:

You can bring a positive at-home test to a Test to Treat site.

A healthcare provider at the Test to Treat site may ask about your medical history or other medications you take in order to make sure you are eligible for treatment.

The two antiviral treatments being prescribed and filled at Test to Treat sites are Paxlovid and molnupiravir (Lagevrio).

The Test to Treat web-based locator can help you find a Test to Treat site near you. You can also call 800-232-0233 to get help in English, Spanish, and more than 150 other languages.

How do I know if I have COVID-19, the flu, or just a cold?

Now that the Omicron variant of COVID-19 is the dominant strain, telling the difference is more challenging than ever. Even if you have been vaccinated and boosted, you can still get symptoms, but they are likely to be mild to moderate in severity. For those not vaccinated, the risk of severe symptoms that can be life-threatening is still substantial.

At the current time, people with "flulike" symptoms should assume they have COVID. If possible, arrange to get tested or do a home test. If the test is positive, you should isolate at home for five days. If you had a negative test when symptoms started, it’s still best to isolate at home for two to three more days, to monitor your symptoms and prevent spreading infection. (That’s because there is a chance of false negatives with antigen tests, which means you can still have COVID with a negative test.) Consider testing again before going out. Once you are ready to leave home, continue to consistently wear a mask for at least five more days.

How Long Before Someone With COVID

Infectious diseases specialists believe that on average the vast majority of people who contract the coronavirus are most contagious immediately before and immediately after symptoms appear. But how long people are contagious for varies from person to person, depending on the severity of their infection, the intensity of their exposure, and the response of their immune system.

Experts say the window of highest infectivity

seems to occur 2 days prior to symptom onset to 3 days after symptom onset.

Rapid antigen tests can detect high viral loads and are currently thought to be reliable in telling people whether or not they could still be contagious.Health officials recommend isolating for 5 to 10 days if you develop COVID-19.

Infectious diseases specialists believe that, on average, the vast majority of people who contract the coronavirus are most contagious immediately before and immediately after symptoms appear.

Research Trusted Source Trusted Source

shows that most people will no longer be contagious 5 to 6 days after symptoms appear. Still, some evidence suggests about one-third

Trusted Source Trusted Source

of people who contract the infection continue to be infectious for a longer period.

Health experts do not recommend using a PCR test to determine if you may still be contagious since these types of tests are sensitive and can detect small amounts of non-infectious viruses.

Rapid antigen tests, on the other hand, can detect high viral loads and are currently thought to be more reliable in telling people whether or not they could still be contagious.

“For a symptomatic infection, the time from illness onset has been shown to be more reliable than PCR testing to predict the presence of live [or] contagious COVID-19 virus,” Dr. Charles Bailey, the medical director for infection prevention with Providence Mission Hospital and Providence St. Joseph Hospital in Orange County, CA, told Healthline.

“Antigen testing may be more capable of determining infectivity since its threshold for detecting COVID-19 more closely aligns with an amount of virus capable of transmission,” he added.

How long are people contagious?

According to Bailey, the length of infectivity will vary from person to person and depends on the severity of infection, the intensity of exposure, and each person’s immune system.

In general, the window of highest infectivity

Trusted Source Trusted Source

seems to occur 2 days before symptom onset to 3 days after symptom onset.

Contact tracing studies

Trusted Source Trusted Source

from earlier in the pandemic have found that it’s less common for transmission to occur when exposed to a person 6 days after their symptom onset.

It’s still possible for people to transmit the virus to others after 5 days of symptoms, which is why health officials are advising people who recently recovered from their illness to continue wearing a mask for 5 days when they’re around other people.

One study recently published in the International Journal of Infectious Diseases found that about one-third of people with the infection continue to be contagious after 5 days.

But it’s unclear if this remains true with the Omicron variant.

A recent study Trusted Source Trusted Source

from Japan found that patients infected with the Omicron variant shed virus for longer after symptoms appear.

The study suggests that the peak of viral shedding with the Omicron variant may be 2 or 3 days longer than previous variants.

Do certain symptoms suggest we’re contagious?

Dr. Julie Parsonnet, an infectious diseases epidemiologist with Stanford Medicine, says there doesn’t appear to be a strong relationship between a person’s symptoms and how much virus is in their nose and throat.

But in general, people who’ve tested positive and are symptomatic are more at risk of transmitting and should isolate at home to avoid transmitting the virus to others.

“People whose symptoms are not improving — particularly if they have coughing and sneezing — should continue to stay home until they’re feeling better,” Parsonnet said.

If someone carrying the virus is coughing or sneezing, there’s a greater chance they can spread the virus to others since they’re releasing respiratory droplets that carry the virus.

Researchers are still studying if and how symptoms correlate to how contagious a person is.

“We don’t exactly how symptom duration relates to how long someone is contagious, but we do typically associate symptoms like fever as indication that someone is still infectious,” said Dr. John Carlo, the CEO of Prism Health North Texas and member of the Texas Medical Association COVID-19 Task Force.

Research Trusted Source Trusted Source

has also shown that people with asymptomatic infections, though less likely than symptomatic individuals to spread the infection, can transmit it to others.

Parsonnet says it’s difficult to quantify how long asymptomatic individuals are contagious because it’s hard to identify when and how long they’ve been infected.

“Asymptomatic transmission might prove to be more common with the Omicron variant given its higher infectivity, but too early to draw this conclusion now,” Bailey said.
