It is generally believed that people with COVID-19, the disease caused by the coronavirus SARS-CoV-2, are most contagious during the early stages of infection, when the virus is being actively shed in the respiratory secretions of an infected person. The length of time that a person is contagious can vary depending on a number of factors, such as the severity of their illness and the presence of underlying health conditions.
It is generally believed that people with COVID-19 are no longer contagious once they have recovered from the infection and are no longer experiencing symptoms. However, the exact length of time that a person is contagious is not fully understood, and more research is needed to determine the duration of infectiousness.
If you have been infected with COVID-19 and are no longer experiencing symptoms, it is generally safe to assume that you are no longer contagious. However, it is always a good idea to follow the guidance of public health authorities and your healthcare provider to ensure that you are taking the necessary precautions to protect yourself and others from infection. This may include wearing a mask and practicing physical distancing, even after you have recovered from the infection.
