Rickettsia prowazekii Typhus Fever

By: Anthony Fitzgerald

How it spreads? What causes it?

Typhus fevers are caused by the rickettsiae bacteria and transmitted by arthropod (e.g. flea, mite, tick) bites. When arthropods bite a victim, they leave the rickettsaie bacteria behind. Scratching the bite opens the skin to the bacteria, allowing them to enter the bloodstream. Within the blood stream, the bacteria grow and replicate.
