   • 2020 May 20, Richard Clinnick, “Network News: More trains... but advice is not to use public transport”, in Rail, page 6:

     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 $U$) A collection of sets $\{U_{i}\}$ such that their union contains $U$; such a collection with the additional property that every $U_{i}$ is open; such a collection with the additional property that every $U_{i}$ is contained in $U$.
5. (topology) A special kind of map that establishes a relationship between two topological spaces in the sense that, under the action of the map, the one looks locally like several copies of the second: Formally, a continuous map $\pi :E\rightarrow X$ between topological spaces such that there exists, for every point $x$ in $X$, a discrete space $D_{x}$ and an open neighborhood $U$ of $x$ such that $\pi ^{-1}(U)=\displaystyle \bigsqcup _{d\in D_{x}}V_{d}$ and $\pi |_{V_{d}}:V_{d}\rightarrow U$ is a homeomorphism for every $d\in D_{x}$. See Covering space on Wikipedia.Wikipedia

Usage notes

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