Professor Gut said: “Infectiveness and the course of the disease are two different things.
“We use a method that is unable to distinguish between an active and inactive virus.
“Therefore, someone finding the virus after three, four, five weeks is news they have found the virus’ genome – an active virus is most likely not there.
“What causes an active virus? Specifically, clinical symptoms – as clinical symptoms subside, parts of the virus remain. Some viruses remain for life.”
Researchers are, however, focused on developing a cure in the shortest time possible.
