If you have tested positive for COVID-19, you may be wondering how long you are contagious and when it is safe to be around others again. The answer depends on several factors, including the severity of your illness, whether you are vaccinated, and whether you are taking any medications.
In general, people with COVID-19 are most contagious in the days leading up to and including the day of symptom onset. This is because the virus is shedding from the respiratory tract in high amounts during this time. After symptoms develop, the amount of virus shedding gradually decreases, and most people are no longer contagious after 10 days. However, some people, especially those who are immunocompromised, may continue to shed the virus for longer periods of time.
how long are you contagious with covid
Here are 8 important points about how long you are contagious with COVID-19:
- Most contagious: days before and including symptom onset
- Contagiousness decreases: after symptoms develop
- No longer contagious: after 10 days for most people
- Immunocompromised: may shed virus longer
- Isolation: recommended for 5 days after symptom onset
- Wear mask: for 5 additional days after isolation
- Avoid contact: with high-risk individuals for 10 days
- Get tested: if symptoms persist or worsen
It is important to note that these are general guidelines. The best way to determine how long you are contagious is to talk to your doctor.
Most contagious: days before and including symptom onset
People with COVID-19 are most contagious in the days leading up to and including the day of symptom onset. This is because the virus is shedding from the respiratory tract in high amounts during this time.
- Virus shedding:
The virus that causes COVID-19 is shed from the respiratory tract of infected people. This can happen even if they do not have any symptoms.
- Most contagious:
People with COVID-19 are most contagious in the 1-2 days before symptoms develop and for the first 2-3 days after symptoms start.
- Symptoms:
The most common symptoms of COVID-19 are fever, cough, and shortness of breath. However, some people may experience other symptoms, such as fatigue, muscle aches, and loss of taste or smell.
- Spread:
COVID-19 is spread through close contact with an infected person. This means being within 6 feet of someone who is coughing, sneezing, or talking. The virus can also be spread by touching surfaces that have been contaminated with the virus and then touching your mouth, nose, or eyes.
It is important to note that even if you do not have symptoms, you can still be contagious and spread the virus to others. This is why it is important to wear a mask and practice social distancing, even if you feel fine.
Contagiousness decreases: after symptoms develop
After symptoms of COVID-19 develop, the amount of virus shedding from the respiratory tract gradually decreases. This means that people are less contagious as their symptoms improve.
- Viral load:
The amount of virus in a person's respiratory tract is called the viral load. Viral load is highest in the days leading up to and including the day of symptom onset. After symptoms develop, viral load gradually decreases.
- Contagiousness:
People with COVID-19 are most contagious when their viral load is highest. This means that they are most contagious in the days before and including the day of symptom onset. After symptoms develop, people are less contagious as their viral load decreases.
- Duration of contagiousness:
Most people with COVID-19 are no longer contagious after 10 days from the date their symptoms started. However, some people, especially those who are immunocompromised, may continue to shed the virus for longer periods of time.
- Isolation and precautions:
People with COVID-19 should isolate themselves from others for at least 5 days after their symptoms start. They should also wear a mask for an additional 5 days after isolation ends.
It is important to note that even if you are feeling better, you may still be contagious. This is why it is important to follow the isolation and mask-wearing guidelines.
No longer contagious: after 10 days for most people
Most people with COVID-19 are no longer contagious after 10 days from the date their symptoms started. This is based on studies that have shown that the amount of virus shedding from the respiratory tract decreases significantly after 10 days.
- Viral load:
As mentioned previously, viral load is the amount of virus in a person's respiratory tract. Viral load is highest in the days leading up to and including the day of symptom onset. After symptoms develop, viral load gradually decreases.
- Contagiousness:
People with COVID-19 are most contagious when their viral load is highest. This means that they are most contagious in the days before and including the day of symptom onset. After symptoms develop, people are less contagious as their viral load decreases.
- Isolation guidelines:
The Centers for Disease Control and Prevention (CDC) recommends that people with COVID-19 isolate themselves from others for at least 5 days after their symptoms start. This is because most people are no longer contagious after 10 days from the date their symptoms started.
- Mask-wearing:
Even after isolation ends, people with COVID-19 should continue to wear a mask for an additional 5 days. This is to help prevent the spread of the virus to others, especially if they are still shedding the virus.
It is important to note that these guidelines are for people who have mild to moderate cases of COVID-19. People who are severely ill may need to isolate for longer periods of time.
Immunocompromised: may shed virus longer
People who are immunocompromised may shed the virus that causes COVID-19 for longer periods of time than people who are not immunocompromised. This is because their immune systems are weaker and less able to fight off the virus.
- Immunocompromised:
People who are immunocompromised have weakened immune systems. This can be due to a variety of factors, such as certain medical conditions (e.g., cancer, HIV/AIDS), medications (e.g., chemotherapy, immunosuppressive drugs), or organ transplants.
- Shed virus longer:
People who are immunocompromised may continue to shed the virus that causes COVID-19 for longer periods of time than people who are not immunocompromised. This is because their immune systems are less able to fight off the virus.
- Increased risk of severe illness:
People who are immunocompromised are also at increased risk of developing severe illness from COVID-19. This is because their immune systems are less able to fight off the virus.
- Precautions:
People who are immunocompromised should take extra precautions to protect themselves from COVID-19, such as getting vaccinated, wearing a mask, and avoiding large gatherings.
It is important to note that even if you are immunocompromised, you can still recover from COVID-19. However, it is important to talk to your doctor about your specific situation and what precautions you should take.
Isolation: recommended for 5 days after symptom onset
The Centers for Disease Control and Prevention (CDC) recommends that people with COVID-19 isolate themselves from others for at least 5 days after their symptoms start. This is because most people are no longer contagious after 10 days from the date their symptoms started, and isolating for 5 days helps to reduce the risk of spreading the virus to others.
- Isolation:
Isolation means staying home and away from other people, including people in your household. You should not go to work, school, or any public places.
- 5 days:
The CDC recommends that people with COVID-19 isolate for at least 5 days after their symptoms start. This is because most people are no longer contagious after 10 days from the date their symptoms started, and isolating for 5 days helps to reduce the risk of spreading the virus to others.
- Monitor symptoms:
While you are in isolation, you should monitor your symptoms closely. If your symptoms worsen or you develop new symptoms, you should contact your doctor.
- End isolation:
You can end isolation after 5 days if your symptoms have improved and you have not had a fever for at least 24 hours without taking fever-reducing medication.
It is important to note that even if you are feeling better, you may still be contagious. This is why it is important to follow the isolation guidelines and wear a mask for an additional 5 days after isolation ends.
Wear mask: for 5 additional days after isolation
Even after you end isolation, you should continue to wear a mask for an additional 5 days when you are around other people. This is because you may still be contagious and able to spread the virus to others, even if you are feeling better.
- Mask-wearing:
Wearing a mask helps to reduce the risk of spreading the virus to others. Masks should be worn over the nose and mouth and fit snugly against the face.
- 5 additional days:
The CDC recommends that people with COVID-19 wear a mask for an additional 5 days after isolation ends. This is to help prevent the spread of the virus to others, especially if you are still shedding the virus.
- Around other people:
You should wear a mask when you are around other people, even if they are members of your household. This is especially important in indoor settings.
- End mask-wearing:
You can stop wearing a mask after 5 additional days if you have not had any new symptoms and your symptoms have improved.
It is important to note that these are general guidelines. The best way to determine how long you should wear a mask is to talk to your doctor.
Avoid contact: with high-risk individuals for 10 days
People with COVID-19 should avoid contact with high-risk individuals for 10 days after their symptoms start. This is because people with COVID-19 are most contagious in the days leading up to and including the day of symptom onset, and they may continue to be contagious for up to 10 days after symptoms start.
High-risk individuals are people who are more likely to get severely ill from COVID-19. This includes people who are:
- 65 years of age or older
- Have certain medical conditions, such as cancer, heart disease, or diabetes
- Are immunocompromised
- Are pregnant
If you have COVID-19, you should avoid contact with high-risk individuals for 10 days after your symptoms start. This means:
- Staying home from work, school, and other public places
- Not having visitors in your home
- Wearing a mask when you are around other people, even if they are members of your household
- Avoiding close contact with people, including handshakes and hugs
- Cleaning and disinfecting surfaces that you touch frequently
- Monitoring your symptoms and contacting your doctor if they worsen
By following these precautions, you can help to protect high-risk individuals from getting COVID-19.
After 10 days, if your symptoms have improved and you have not had a fever for at least 24 hours without taking fever-reducing medication, you can end isolation and resume normal activities. However, you should continue to wear a mask when you are around other people for an additional 5 days.
Get tested: if symptoms persist or worsen
If you have COVID-19 and your symptoms persist or worsen, you should get tested again. This is because you may still be contagious and able to spread the virus to others.
- Symptoms persist:
If your COVID-19 symptoms do not improve after 10 days, or if they get worse, you should get tested again.
- Symptoms worsen:
If your COVID-19 symptoms worsen at any time, you should get tested again. This is especially important if you develop new symptoms, such as shortness of breath, chest pain, or confusion.
- Get tested:
If you need to get tested again, you can contact your doctor or local health department. They will be able to tell you where to get a test and how to get your results.
- Isolate:
While you are waiting for your test results, you should isolate yourself from others. This means staying home from work, school, and other public places.
It is important to note that even if you have a negative test result, you may still be contagious. This is because tests are not always 100% accurate. If you are still experiencing symptoms, you should continue to isolate yourself from others and follow the CDC's guidelines for preventing the spread of COVID-19.
