When it started from Wuhan we did not hear too much about reinfection. Then we found few reports from South Korea, Japan, USA and many other states too. What might be the factors related to reinfections of COVID-19 cases?
The reinfection is proven to be correct. As it appears, not all cases will be fully immuned once infected.
It is hard to say yes or no. We need more time, more studies, and evidence.
There is a chance but not in every one according to published researches
well closing the borders so no new infected would reduce infection rate the virus would run through and it would be over. Also, each case of coronavirus is genetically unique so you would need a biological method not a chemical on to end the virus life cycle
Yes, because immunity after COVID-19 infection is short-lived (like coronaviruses causing common cold) second and repeat infections are a real possibility.
