Content warning: useful article on measles transmission
From Helen Branswell back in 2019:
"Let’s take a look at the tricks measles has up its sleeve: ...
"The so-called infectious dose for measles is small. And people who are infected emit a lot of viruses as they cough or even exhale. ...
"After someone breathes or coughs out the viruses, they can remain in the air for significant periods of time. In fact, it’s estimated that a susceptible child who entered a room — say a doctor’s waiting room — two hours after an infected child was there can become infected. ...
"... people who contract the virus are contagious for about eight days. Most importantly from a transmission point of view, half of that time is before they have developed the rash that typically lets people know: This child has measles. ...
"The introduction of measles vaccine drove down the number of cases to the point that now some doctors don’t recognize measles when confronted with it. ...
"The good news is the measles vaccine is one of the best around. Two doses of vaccine in childhood protect about 97 percent of the children who receive it."
