how long are you contagious with covid ?
The incubation period, often known as the duration between exposure and symptom onset, is thought to be 2–14 days, according to experts. Symptoms, on the other hand, usually develop 4–5 days after exposure.
One study from the year 2021 129 individuals hospitalized with COVID-19 were enrolled in the Trusted Source study.
Participants continued to shed the virus for an average of 8 days after initially experiencing symptoms. The chances of continuing to shed the virus were fewer than 5% at 15.2 days.
These findings imply that shedding may last longer than two weeks in some COVID-19 patients. The study, however, only included participants who were being treated in a hospital for COVID-19 that was moderate to severe. It's unclear whether the outcome would be the same for those with mild or asymptomatic illness at this time.
When do people become the most contagious?
A person with COVID-19 is most contagious in the first week of sickness, according to a 2021 reviewTrusted Source. As a result, they may be the most contagious just before and after symptoms begin.
As a result, people should isolate themselves immediately if they suspect they have come into touch with the virus.
What if there aren't any signs or symptoms?
Determining contagiousness in persons who do not have symptoms is problematic, as many people who do not have symptoms may never be aware that they have COVID-19.
A person is asymptomatic if they have no symptoms. If a person does not exhibit symptoms at first but later develops them, they are said to be pre-symptomatic.
According to a study published in 2020, both asymptomatic and presymptomatic people can and do spread the virus.
The study looked at 31 persons who were hospitalized for various reasons but tested positive for COVID-19 but had no symptoms. Twenty-two of the patients acquired symptoms over time, while nine never did.
