The way i look at it if contact sports are currently happening such as bfkc, mma ,boxing, football, rugby then catfights can happen. Just precautionary measures need to be taken you know your fighting in 2weeks you isolate within reason you where your mask everywhere. Day of fight you have a temperature check temp gun shower use hand sanitizer after fight shower again. Room well ventilated should be no problem. obviously you have a temp you can't fight.
