anyone who isn't immune to yellow fever or hasn't received a vaccination is susceptible to yellow fever if bitten by a mosquito that has bitten a monkey or person carrying the virus. there was a massive yellow fever epidemic in 1793 in Philadelphia where over 5,000 people died and were thrown into ditches so that it wouldn't be spread around. Then another one in Memphis in 1878 though not limited to those two cities. it is found all over the world and is responsible for 30,000 deaths annually in unvaccinated regions.
