roles of mosquitoes in diseases

• • Only female mosquitoes suck blood, and the reason they do this is to obtain the iron they need to grow eggs and reproduce. Pathogens can rely on mosquitoes to transport them to a new host
• • A mosquito takes up the blood of an infected individual, and also takes up pathogens floating in the blood. The pathogen replicates within the mosquito and is later injected into a non-infected individual when the mosquito bites them
• • Each point, pathogens flow easily from one host to another because when mosquitoes feed, they inject anticoagulants→ that prevent the blood from clotting
• • In this way, mosquitoes act as a vector: organisms that transmit disease from one host to another
