Rickettsialpox is a rickettsial infection, specifically a type of bacterial infection, caused by Rickettsia akari. It is typically transmitted to humans through the bite of an infected mite.

Symptoms[edit | edit source]

The symptoms of rickettsialpox typically appear within one to two weeks after the bite of an infected mite. The initial symptom is often a small, painless bump (eschar) at the site of the mite bite. This is followed by the sudden onset of flu-like symptoms, including fever, chills, headache, and muscle aches. A widespread rash typically appears within a few days of the onset of fever.

Diagnosis[edit | edit source]

The diagnosis of rickettsialpox is typically made based on the characteristic symptoms and history of exposure to mites. Laboratory tests can confirm the diagnosis, but these are not always necessary.

Treatment[edit | edit source]

Rickettsialpox is typically treated with antibiotics, such as doxycycline or tetracycline. Most people recover fully with appropriate treatment.

Prevention[edit | edit source]

Prevention of rickettsialpox involves avoiding exposure to mites. This can be achieved by keeping homes clean and free of mites and by using insect repellents.
