Explanation:
What Causes Rocky Mountain Spotted Fever?
Rocky Mountain spotted fever (RMSF) is a potentially fatal tickborne disease caused by the bacterium Rickettsia rickettsii. This bacterium is transmitted to humans primarily through the bite of infected hard-bodied ticks, such as the American dog tick (Dermacentor variabilis), the Rocky Mountain wood tick (D. andersoni), or the brown dog tick (Rhipicephalus sanguineus). When a person is bitten by an infected tick, they can develop symptoms such as fever, body aches, and a characteristic rash that often starts on the hands and wrists and then spreads to the trunk.
It is important to recognize the symptoms early, as RMSF can be life-threatening if not treated promptly with antibiotics.
