Coronavirus could be most contagious before symptoms occur, study suggests

Research from the scientists at the Bundeswehr Institute of Microbiology found that transmissions are likely being driven by the coronavirus’ high rate of viral shedding.

This refers to the process of the virus replicating itself and then spreading into other parts of the host’s body or the environment where they could continue the process, early on in infection.

The highest levels of virus were found in the throats of patients in the earliest stages of infection and before they feel unwell, which is when they are most likely to be walking about and coughing, spreading the virus.
