Solution
The correct option is C Typhoid
Brain fever is caused by virus and transmitted through Culex tritaeniorhynchus, female mosquitoes. Mosquitoes acquire virus, while taking blood meal and pass it to next healthy person.
When Anopheles female mosquito bites a malaria patient then malarial parasite also enters in mosquito, while blood suction. Malarial parasite can grow in mosquito body and pass to another person, when mosquito bites. Dengue virus is transmitted due to mosquitoes, Aedes aegypti.
Typhoid is caused by bacteria called as Salmonella typhi. It is water borne disease. Typhoid patient's feces show presence of Salmonella typhi. When such feces comes in contact with drinking water bodies then water gets polluted. Such, water if used for consumption then person gets infected with typhoid. Hence, typhoid is not transmitted by mosquito.
