I would take this very seriously if contacted. Rabies can have a very long incubation time before symptoms develop. Post exposure prophylaxis administered in a timely manner is very effective.

Measles virus diverged phylogenetically from rinderpest bovine virus. I did not know that.
Measles likely came from cows (via rinderpest) around the 6th century BCE.
For 2,500 years, we didn’t evolve superhuman resistance—children just died. Real protection only came in the 1960s, with vaccines.
Our superpower isn’t evolving into superhumans. It’s outthinking pathogens.
