They have to make sure to catch and test that squirrel or those poor elderly people are going to go through hell.
Squirrels hardly ever carry diseases that are transmissible to humans, so that’s not something to worry a whole lot about. As long as they disinfect the bite to get rid of bacteria, they should be just fine.
Squirrel bites can hurt a lot, but their teeth are so tiny, it’s like getting poked with a sharp needle, or a deep paper cut. Hardly any tissue damage at all.
