The majority of reinfections occur at least 90 days after the initial COVID-19 infection.
Is it possible to get Omicron twice? The Omicron variant spreads easier than other variants of coronavirus, and people can get it twice. Reinfection is possible even if a person has already had this virus or is fully vaccinated.
Some people can test positive for COVID-19 for weeks or even months on PCR tests, but there is good news: people are not likely to be contagious for that long from a single infection, even if they test positive, and therefore are unlikely to transmit the virus to others.
You can pass on the infection to others, even if you have no symptoms. 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.
After a positive test result, you may continue to test positive for some time. Some tests, especially PCR tests, may continue to show a positive result for up to 90 days.
We are finding that some of our patients are testing positive for coronavirus over a period of weeks and months after they have recovered from COVID-19 and are asymptomatic. Sometimes results are changing from positive to negative and then back to positive again. This is well described in other hospitals.
Unfortunately, yes—it is possible.
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).
Even if mild symptoms remain, you are likely not contagious after 10 days.
Studies suggest that reinfection with SARS-CoV-2 with the same virus variant as the initial infection or reinfection with a different variant are both possible; early reinfection within 90 days of the initial infection can occur.
Common questions about COVID reinfection
Immunity is highest in the following weeks after infection. After a few months, those antibodies will go down. With the emergence of new variants, it is possible to be infected again, so it's best to take precautions to protect yourself from reinfection.
Can you get Covid-19 twice? Yes, it is possible to get Covid-19 two, three or even more times. Covid reinfections have become more common because of the Omicron variant, and because immunity from previous infection and immunisation has reduced over time.
You are most infectious (or contagious) in the first 5 days after your symptoms start. 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.
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. You may also be exposed to the virus afteryou are tested and then get infected.
Still, 19% of those who were asymptomatic continued to test positive on day 10, the study found. Keep in mind that it's possible to get COVID-19 more than once — even three or four times. So if there's a gap of weeks or months in between your positive tests, you might actually have a new infection.
COVID-19 rebound is when people with COVID-19 get better, then begin to get symptoms 2-8 days after they have recovered. They may also test positive again. COVID-19 rebound is seen in people who received treatment for COVID-19 as well as in people who did not receive treatment.
It's also possible to get a positive test result followed by a negative result. If you use two different pregnancy tests, this could be the result of varying test sensitivity. Wait a few days and test again. You also may no longer be pregnant.
The most common long-haul COVID symptoms include lung problems like shortness of breath and a cough that doesn't go away.
Some infections can leave you with a dry cough because your lungs have been irritated. This should slowly disappear during the course of your recovery. It's not clear how long after coronavirus (COVID-19) you may have a cough and it can be frustrating at times.
Common symptoms of COVID-19 respiratory infections in the airways and lungs may include severe cough that produces mucous, shortness of breath, chest tightness and wheezing when you exhale.
Green and cloudy: viral or bacterial infection
A lot of the symptoms of viral infections – fever, cough, headache, loss of smell – overlap for COVID-19 and other viral infections like the flu, respiratory syncytial virus and the common cold.
Does coughing up mucus mean you're getting better? In most cases, coughing up mucus means your body is working to fight off an infection, and it is in the healing stages. Drink plenty of fluids to help thin the mucus.
If your cough is ongoing after 4 weeks, it is important to contact your GP or primary care team in case there is another cause for your cough.
People with Long COVID can have a wide range of symptoms that can last weeks, months, or even years after infection. Sometimes the symptoms can even go away and come back again.
