Rocky Mountain spotted fever is a bacterial infection that can be serious if left untreated. However, there are several synonyms for the condition, including tick-borne typhus, boutonneuse fever, and Mediterranean spotted fever. These names all refer to similar conditions caused by different bacteria, though the symptoms may differ slightly. It is important to seek medical attention if you suspect that you have any type of spotted fever, as prompt treatment can greatly reduce the risk of complications. Early symptoms may include fever, headache, and rash, so be sure to seek medical attention if these symptoms occur, especially if you have recently been in an area where ticks are common.
