Rickettsialpox

Rickettsialpox is a mite-borne infectious illness caused by bacteria of the genus Rickettsia (Rickettsia akari). Physician Robert Huebner and self-trained entomologist Charles Pomerantz played major roles in identifying the cause of the disease after an outbreak in 1946 in a New York City apartment complex, documented in "The Alerting of Mr. Pomerantz," an article by medical writer Berton Roueché.

Although it is not transmitted by a tick (a characteristic of spotted fever), the bacterium is a part of the spotted fever group of Rickettsia, and so this condition is often classified with that group.
