Is yellow fever in the US?
From CDC.gov website:Why is yellow fever not found in the United States presently? Has it not occurred in the past?The last yellow fever epidemic in the United States occurred in New Orleans in 1905.Yellow fever is primarily transmitted by Aedes aegyptimosquitoes. This particular type of mosquito is currently only found in the southern United States. For yellow fever to be introduced into the country, someone who is very recently infected with yellow fever has to visit or live in a location inhabited by Aedes aegypti mosquitoes. Then, that person has to be bitten by an Aedes aegypti mosquito that then bites and infects another person. This would have to happen many times for an outbreak of yellow fever to occur.Low occurrence of yellow fever world wide makes the introduction of yellow fever into the U.S. less likely. Additionally, many Americans are able to use preventative measures and secure their homes with tight fitting screens and air conditioning to prevent their exposure to mosquitoes.
