i literally just got told that its not a big deal and we arent under-reacting because mumps and the measles also has a transmissible period where patients are asymptomatic.
at which point i just quietly realized that some people are contrarian. you can point out a train coming while they are standing on the tracks and half way through their explanation of how they dont need to worry about it because they can get off the tracks at any time they get hit.
