It seems that a college student “infected with the contagious disease” (measles) rode on the Bay Area Rapid Transit system last week. This semi-legitimately has the public health folk concerned and they’ve made the usual announcements warning people (10,000? 100,000?) who rode the trains, etc., etc. The BART/gov’t publicity is directly related to two separate issues. The first, of course, is the lack of vaccination due to the [unfavorable descriptive terms deleted] folk like that science and education deficient Hollywood actress who has become a self proclaimed expert on that completely discredited vaccine <-> autism link. Oh, and her cohort in science illiteracy, RFK Jr., who mouths similar claims.
The other issue is the intense fear and possible overreaction that these incidents lead to. While there are measles outbreaks when an infected kid is at a summer camp or a school, I’ve never heard of a similar issue (that’s not to say there haven’t been any) from the more casual and fleeting contact on a subway train.
