Even if they find a cure right now, it will still take time to mass-produce and distribute it. It will really take time before the world will be back to normal.
But at least this will add confidence to people to go out because they are certain they'll not get infected again.
Even for let's say there's a cure that made right now, it won't give confidence to people to go out. The vaccine might kill the virus but it will not give an assurance that it also has a sort of immunity boost against it. It needs lots of time for a cure + immunity to be made. Therefore, being re-infected is always possible even they find a cure right now. Like I said in another thread, the term
"Pandemic" is the highest level of spread meaning being infected has a high chance to happen even just for a few seconds of being close to the infected ones.
NBA is done this season. The number of virus-related concerns is still growing. Even all NBA players, staff or should I say, the whole USA will be a virus-free country this month or two, I think no one will have the guts to play alongside those reportedly infected players. The worries are always there. Not a disrespect but they just want to be safe.
