      Face covering is also mentioned: "There are some circumstances when wearing a face covering may be marginally beneficial as a precautionary measure. The evidence suggests that wearing a face covering does not protect you, but it may protect others if you are infected but have not yet developed symptoms. [...] If you can, wear a face covering if you need to use public transport."
  2. (uncountable) Action of the verb to cover.
  3. (topology, of a given open set  ) A collection of sets   such that their union contains  ; such a collection with the additional property that every   is open; such a collection with the additional property that every   is contained in  .

Usage notes
edit

In sense sense 4, properly, the map   is the covering, and   is called the covering space, but by abuse of terminology, "covering" may refer to  , "covering space" may refer to  , and either may refer to the tuple  .
