Seems IPL matches is also going to get affected due to corona outbreak since it has been announce pandemic disease where there is lot of money involves in betting every year.So yes it is affecting the whole world even we might see no one entering casinos in near future until this outbreak will be under control.
I do not think the matches will be postponed, I think they will happen without any spectators in the stadium. A huge amount of money has already been invested and BCCI President has already declined that IPL will be cancelled or postponed due to the virus outbreak.
