توضیح
A disease vector is an organism that transmits disease-causing pathogens from one host to another. Female Anopheles mosquitoes can carry and transmit the Plasmodium parasite, which causes malaria. When an infected mosquito bites a person, it injects the parasite into the bloodstream, leading to the transmission of the disease.
