This disease is caused by the bacterium Rickettsia conorii and is characterized by fever, headache, and a rash that resembles a group of small bumps or pimples. Some common synonyms for boutonneuse fever include Mediterranean spotted fever, Kenya tick typhus, Israeli spotted fever, and African tick bite fever. This disease is endemic to certain regions of the world, including the Mediterranean basin, Africa, and Asia. To avoid boutonneuse fever, it is important to take measures to avoid tick bites, such as wearing protective clothing and using insect repellents.
