I think coronavirus is going to end by June

This is my prediction, don't take it for granted. Unfortunately it's not possible to include pics in posts here, but the chart of Sars-1 shows that it peaked end of April/beginning of May and disappeared in June.

Compare that to the current pandemic of Sars 2/Coronavirus. The daily increase started to stagnate by the end of March and will likely collapse soon, once it gets hotter. Combined with most people using face masks and countries getting better at tracking cases, the virus won't be around for long.
