Measles and chicken pox are the two most highly contagious respiratory route viruses I know of, and measles in adults is VERY bad news.
I caught measles from a patient when I was 28 and I was out of work for 3 months.
Not being immunized (for measles) is absurd.
Nothing wrong with getting immunized and I’m hopeful that as a society we’ll get back to getting conventional vaccinations and I hope schools maintain standards about requiring kids to be vaccinated in order to be able to attend.
