Which of the following diseases is NOT carried by rodents?

• A. Leptospirosis
• B. Salmonellosis
• C. Malaria
• D. Hanta virus

Answer: (C)

Malaria is not carried by rodents, making it the correct answer. This disease is primarily transmitted to humans through the bites of infected female Anopheles mosquitoes. In contrast, the other diseases listed—Leptospirosis, Salmonellosis, and Hantavirus—are associated with rodents. Leptospirosis is a bacterial disease that humans can contract from water contaminated with the urine of infected animals, including rodents. Salmonellosis, caused by Salmonella bacteria, can result from handling rodent feces or contaminated food. Hantavirus is a serious viral infection primarily carried and transmitted through the droppings, urine, and saliva of infected rodents, particularly in certain environments where their populations are large. Understanding these transmission methods highlights why malaria is not related to rodent activity, as it relies on a completely different vector.
