You can also spread COVID-19 in the 48 hours before your symptoms start. If you never have symptoms, consider yourself most infectious in the 5 days after you test positive.
People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
You can end isolation early, after Day 5, if: You have no fever for 24 hours without taking fever-reducing medication, AND. Your other symptoms are gone or improving.
You may be infectious for up to 10 days. You are most infectious in the 2 days before your symptoms start and while you have acute symptoms (such as a runny nose, sore throat, fever, cough). Some people with COVID-19 do not develop symptoms at all but are still able to infect others.
If you are significantly immunosuppressed, you are more likely to be infectious for longer than 7 days and may still be able to spread the virus. Follow these measures until day 14 following your positive test result to further reduce any remaining risk of spreading the virus.
You are contagious for the entire period of time symptoms are present, all the way until they disappear.
If you continue to test positive on repeat testing through 10 days, you should continue to wear a mask and avoid people who are immunocompromised or at high risk for severe disease until you receive two sequential negative antigen test results.
You may need to get tested even if you do not have symptoms. You can have COVID-19 and spread it to others even if you do not have symptoms. Your COVID-19 test can be negative even if you are infected. Most people do not test positive for the virus until days after exposure.
Your infectiousness is highest 1 day before the start of your symptoms and begins to wane about a week later for most people. The Omicron variant has a shorter incubation period, compared to other variants. For the Omicron variant, the incubation period is 1 to 4 days.
Although many people will no longer be infectious to others after 5 days, some people may be infectious to other people for up to 10 days from the start of their infection. If you have a high temperature or still feel unwell after the 5 days, continue to try to stay at home.
You can spread the common cold from a few days before your symptoms appear until all of the symptoms are gone. Most people will be contagious for up to 2 weeks. Symptoms are usually worse during the first 2 to 3 days, and this is when you're most likely to spread the virus.
People with no symptoms can also spread the coronavirus to others. By the 10th day after COVID symptoms begin, most people will no longer be contagious, as long as their symptoms have continued to improve and their fever has resolved.
Try to stay at home and avoid contact with other people
Most people with COVID-19 will no longer be infectious to others after 5 days. If you have a positive COVID-19 test result, try to stay at home and avoid contact with other people for 5 days after the day you took your test.
4. HOWEVER, if you have tested negative for COVID, you shouldget retested if: If you test positive for COVID-19and follow isolation instructions, you will notneed retesting. (this includes multiple shorter periods in the same day that add up to 15 minutes.)
Ask for an urgent GP appointment or get help from NHS 111 if: you're worried about your or a child's COVID-19 symptoms or are not sure what to do. the symptoms are getting worse or are not getting better.
You cannot end your self-isolation early, even if you later test negative during the 7 days. You do not need to wait for an official message to leave self-isolation.
Ending isolation: You can end isolation after 5 days if you test negative (use an antigen test) on Day 5 or later – as long as you do not have a fever and your symptoms are getting better. If you still test positive on or after Day 5 or if you don't test, isolate for 10 full days, and until you don't have a fever.
The study also found that the false-negative rate is at a low point about 8 days after exposure. If you've been exposed to COVID-19 or test positive, it's important to take precautions so you don't infect your loved ones.
Sometimes, people can get a positive COVID-19 test result even though they no longer have COVID-19. This is because people with COVID-19 have infected cells in their body that release the virus into the environment through breathing, sneezing or coughing, or through their faeces and urine.
If you see any line on your COVID test, err on the side of caution and take precautions to avoid spreading the virus to others. While a dark line that shows up quickly is a sign that there's more virus in your body, even a faint line can be positive (and may turn darker if you test again in the coming days).
If you believe you are severely immunocompromised and you are still LFD positive on Day 14 then you should discuss your return to work with Occupational Health (Team Prevent).
If you still have cough and fever after 20 days, continue to stay home until 24 hours after: o the fever has gone away (without using a fever-reducing medication like Tylenol or ibuprofen) AND o your symptoms, such as cough, body aches, sore throat, have improved.
You can only leave self-isolation after 7 days if you do not have a sore throat, runny nose, cough or shortness of breath.
