Which disease is transmitted through a tick bite?

• A. Murine typhus
• B. Scabies
• C. Q fever
• D. All of the above

Answer: (C)

The disease that is transmitted through a tick bite is Q fever. Q fever is caused by the bacterium Coxiella burnetii and is primarily associated with exposure to infected animals, particularly livestock, but the significant transmission route involves tick vectors. Ticks can harbor the pathogen and transmit it during feeding, which highlights their role in the epidemiology of this disease. In contrast, murine typhus is typically transmitted by fleas that are infested with the Rickettsia typhi bacteria, whereas scabies is caused by an infestation of the skin by the Sarcoptes scabiei mite and is not transmitted through ticks at all. Therefore, the notion that all of the diseases listed could be tick-borne is incorrect, thus solidifying Q fever as the correct answer.
