Rickettsia felis is a pathogen that causes flea-borne spotted fever. The infection caused by rickettsia felis spreads via bites from infected cat fleas and impacts people throughout Africa, as well as most other areas of the world.
The first instance of a human rickettsia felis infection was documented in 1991, so not much is known about the pathogen. As research continues, more information will become available that can help people avoid infections and secure the proper treatment should they acquire flea-borne spotted fever.
People infected by rickettsia felis often exhibit the following symptoms:
Most reported cases involving flea-borne spotted fever caused by rickettsia felis exhibit a combination of these symptoms. In Africa, rickettsia felis is associated with many fevers of an unknown origin, which can make diagnosis challenging. However, a definitive diagnosis can be reached via blood testing for the pathogen.
Because rickettsia felis is a type of bacteria, treatment with antibiotics can prove effective. In the past, doxycycline been successfully used to treat bouts of flea-borne spotted fever resulting from rickettsia felis. Possible side effects of doxycycline include:
Other side effects can also occur. Your doctor will explain your risk of side effects and help you determine whether this medication is right for you. Doxycycline may not be suitable for people with allergies to the medication, as well as those who are currently pregnant.
It may not always be possible to avoid rickettsia felis infections. If you live in an area where infections occur, using insect repellent can be beneficial. Similarly, wearing long-sleeved shirts and pants when concerned about flea bites can also help.
