Murine typhus
Murine typhus (also called endemic typhus) is a form of typhus transmitted by fleas (Xenopsylla cheopis), usually on rats. (This is in contrast to epidemic typhus, which is usually transmitted by lice.) Murine typhus is an under-recognized entity, as it is often confused with viral illnesses. Most people who are infected do not realize that they have been bitten by fleas.
