Google is temporarily banning ads for medical face masks, which have proliferated online as the coronavirus spreads.

Google said it is "continuing to evaluate" whether the ban should apply to other products, and said will take a "few days" to take down existing mask ads, meaning users are likely to still see them in the coming days.
