Spreads from infected-animal saliva to people via a bite or broken skin. It kills around two people each year in the U.S., and has a high fatality rate, LiveScience notes: Just three people in this country are known to have survived without receiving the rabies vaccine after exposure to the virus.
Spreads mainly through sex or sharing needles with someone with HIV. Infects about 50,000 people a year, and has killed approximately 640,000 people in the U.S. since 1981.
