Dear Researchers, What if Covid-19 ends and returns in a new way with a new challenge ? Are we prepared enough to face that? I think it largely depends on our (human) reactions and activities. Our awareness, preparedness and a potential vaccine can save us this time by the grace of the almighty. Scientific invention and natural conservation may resist the return of this kinda virus as per as global warming is a rising concern. On the other hand, if it is a part of global politics (Bio-war) among super powers, only God knows what is waiting for us, the common people/countries. Because , I am afraid if it so, there might be counter attack. Lets see what is waiting for us. What do you think in this regard? -Shamsuddoha
