Correct Answer: Malaria

Solution : The correct option is Malaria .

Female Anopheles mosquitos are the primary vectors of malaria. When these mosquitoes feed on the blood of an infected person, they become infected with the malaria parasite (Plasmodium). Through its bites, the infected mosquito can spread the parasite to other humans. Recurrent fever, chills and flu-like symptoms characterise it. Malaria, if left untreated, can be severe and even lethal.
