The bat influenza; originated in the Andes Mountain. It comes from bats and it resembles the common human flu in early stages but if gone untreated can be deadly. Sadly, there is not yet a cure. It is rumored to turn you into a vampire, instead of death, if gone untreated.
OMG, Linda was just in Mongola! I heard she got the bat flu.
