Cross-infections with coronavirus, Covid-19 Ping-Pong ?


Allegedly, a cured Japanese woman has become infected with the virus again. Also in China some patients avoid the hospitals because they fear cross-infection.


Up to now I knew this only with certain venereal diseases. This is feared in Ping-Pong where the partners infect each other over and over again.
But that this also exists with viral diseases is new to me.
