What causes Rocky Mountain spotted fever?

Rocky Mountain spotted fever is caused by the bacterium Rickettsia rickettsii, which is primarily transmitted to humans through the bites of infected ticks, particularly the Dermacentor variabilis (American dog tick) and the Dermacentor andersoni (wood tick). Ticks are arachnids that latch onto animals or humans to feed on blood, and it is during this feeding process that they can transmit Rickettsia rickettsii.

Understanding the vector involved in the transmission of diseases is crucial in nursing practice, as it informs prevention strategies and patient education. For instance, identifying areas where ticks are prevalent, advising on protective measures during outdoor activities, and recognizing the symptoms of tick-borne illnesses all stem from knowledge of tick transmission.

The other options, such as mosquitoes, general insects, or fleas, do not play a role in the transmission of Rocky Mountain spotted fever. This specificity in vectors is essential for accurate diagnosis and management of the disease.
