If you've tested positive for COVID-19, you're probably wondering how long you'll be contagious and when you can expect to test negative. The answer depends on a number of factors, including the severity of your illness, your immune system, and whether or not you're taking antiviral medication.
In general, people who have mild cases of COVID-19 will start to test negative within a few days after their symptoms resolve. However, it's important to note that you can still be contagious for up to 10 days after you start feeling better. This is because the virus can still be present in your body, even if you're not showing any symptoms.
If you have a more severe case of COVID-19, it may take longer for you to test negative. People who are hospitalized with COVID-19 may continue to test positive for up to 20 days after their symptoms resolve.
How Long to Test Negative for COVID
Factors affecting negative test:
- Severity of illness
- Immune system strength
- Antiviral medication
- Mild cases: few days
- Severe cases: up to 20 days
- Contagious up to 10 days
- Isolate until negative test
- Follow public health guidelines
It's important to follow public health guidelines and isolate until you test negative to prevent spreading the virus to others.
Severity of Illness
The severity of your COVID-19 illness can affect how long it takes you to test negative.
- Mild illness:
People with mild cases of COVID-19, such as those who have cold-like symptoms or no symptoms at all, may start testing negative within a few days after their symptoms resolve.
- Moderate illness:
People with moderate cases of COVID-19, such as those who have pneumonia or other respiratory problems, may take up to 10 days to test negative after their symptoms resolve.
- Severe illness:
People with severe cases of COVID-19, such as those who are hospitalized or require oxygen therapy, may take up to 20 days or longer to test negative after their symptoms resolve.
- Critical illness:
People who are critically ill with COVID-19 may continue to test positive for the virus for several weeks or even months after their symptoms resolve.
It's important to note that these are just general guidelines. The amount of time it takes for you to test negative may vary depending on your individual circumstances.
Immune System Strength
The strength of your immune system can also affect how long it takes you to test negative for COVID-19.
- Strong immune system:
People with strong immune systems may be able to clear the virus from their bodies more quickly and may test negative sooner than people with weaker immune systems.
- Weak immune system:
People with weak immune systems, such as those who are elderly, have chronic health conditions, or are taking immunosuppressive medications, may take longer to clear the virus from their bodies and may test positive for longer periods of time.
- Immunocompromised individuals:
People who are immunocompromised may continue to test positive for COVID-19 for several months or even years after their initial infection.
- Vaccinated individuals:
People who are vaccinated against COVID-19 are more likely to have strong immune responses and may test negative sooner than people who are unvaccinated.
If you have a weakened immune system, it's important to take extra precautions to avoid getting COVID-19, such as wearing a mask, social distancing, and getting vaccinated.
Antiviral Medication
Antiviral medications can help to reduce the severity of COVID-19 and may also help to shorten the amount of time that you test positive for the virus.
The antiviral medication Paxlovid has been shown to be effective in reducing the risk of hospitalization and death from COVID-19. Paxlovid is a combination of two antiviral drugs, nirmatrelvir and ritonavir. It is taken orally twice a day for five days.
Another antiviral medication, remdesivir, has also been shown to be effective in treating COVID-19. Remdesivir is given intravenously (IV) once a day for three to five days. It is typically used in hospitalized patients with severe COVID-19.
Antiviral medications are most effective when they are taken early in the course of the illness. If you have COVID-19 and are at high risk of developing severe illness, talk to your doctor about whether antiviral medication is right for you.
It's important to note that antiviral medications are not a cure for COVID-19. They can help to reduce the severity of the illness and may help to shorten the amount of time that you test positive for the virus, but they do not eliminate the virus from your body completely.
Mild Cases: Few Days
People with mild cases of COVID-19, such as those who have cold-like symptoms or no symptoms at all, may start testing negative within a few days after their symptoms resolve.
This is because people with mild cases of COVID-19 typically have lower levels of the virus in their bodies. As their immune systems clear the virus, the amount of virus in their bodies decreases, and they become less likely to test positive.
In most cases, people with mild COVID-19 will test negative within 7 to 10 days after their symptoms start.
However, it's important to note that some people with mild COVID-19 may continue to test positive for the virus for up to 14 days or longer. This is more likely to happen in people who have weakened immune systems.
If you have a mild case of COVID-19, it's important to isolate yourself from others until you test negative. This will help to prevent the spread of the virus to others.
Severe Cases: Up to 20 Days
People with severe cases of COVID-19, such as those who are hospitalized or require oxygen therapy, may take up to 20 days or longer to test negative after their symptoms resolve.
This is because people with severe cases of COVID-19 typically have higher levels of the virus in their bodies. It takes their immune systems longer to clear the virus, and they are more likely to continue testing positive for the virus for a longer period of time.
In some cases, people with severe COVID-19 may continue to test positive for the virus for several weeks or even months after their symptoms resolve. This is more likely to happen in people who have weakened immune systems.
Even if you have a severe case of COVID-19 and continue to test positive for the virus for a long period of time, it's important to remember that you are not necessarily contagious. Studies have shown that people with COVID-19 are most contagious in the early stages of the illness, when they have high levels of the virus in their bodies. As the virus levels decrease, so does the risk of transmission.
If you have a severe case of COVID-19, it's important to follow your doctor's instructions and isolate yourself from others until you are cleared to leave isolation.
Contagious Up to 10 Days
People with COVID-19 are most contagious in the early stages of the illness, when they have high levels of the virus in their bodies. The virus can be spread to others through respiratory droplets that are produced when an infected person coughs, sneezes, or talks.
- Most contagious:
People with COVID-19 are most contagious in the 1-2 days before they develop symptoms and for the first 10 days after their symptoms start.
- Still contagious:
Some people may continue to be contagious for a few days after their symptoms resolve. This is more likely to happen in people who have weakened immune systems.
- Not contagious:
People who have had COVID-19 and have recovered are generally not contagious after 10 days, even if they continue to test positive for the virus.
- Isolation:
If you have COVID-19, it's important to isolate yourself from others for at least 10 days to prevent spreading the virus.
To protect yourself and others from COVID-19, it's important to get vaccinated, wear a mask in indoor public spaces, and practice social distancing.
Isolate Until Negative Test
If you have COVID-19, it's important to isolate yourself from others until you test negative. This will help to prevent the spread of the virus to others.
The CDC recommends that people with COVID-19 isolate for at least 5 days. After 5 days, if you have no symptoms or your symptoms are improving, you can end isolation if you test negative on a rapid antigen test. If you continue to have symptoms after 5 days, you should continue to isolate and retest until you have a negative test result.
If you have a severe case of COVID-19, you may need to isolate for longer than 10 days. Talk to your doctor about when it is safe for you to end isolation.
While you are isolating, it's important to stay in a separate room from other people in your household. You should also use a separate bathroom, if possible. Wear a mask when you are around other people, and wash your hands frequently.
Getting tested for COVID-19 is the only way to know for sure if you are still contagious. If you have any symptoms of COVID-19, or if you have been exposed to someone with COVID-19, get tested right away.
Follow Public Health Guidelines
In addition to isolating until you test negative, it's important to follow public health guidelines to help prevent the spread of COVID-19.
These guidelines include:
- Wear a mask: Wear a mask that covers your nose and mouth when you are in indoor public spaces.
- Practice social distancing: Stay at least 6 feet away from other people when you are in public.
- Get vaccinated: Getting vaccinated against COVID-19 is the best way to protect yourself and others from the virus.
- Wash your hands frequently: Wash your hands with soap and water for at least 20 seconds, especially after coughing, sneezing, or touching surfaces in public places.
- Stay home if you are sick: If you are sick, stay home from work or school and avoid contact with others.
By following these guidelines, you can help to slow the spread of COVID-19 and protect yourself and others from the virus.
