Question

How do mosquitoes carry disease -causing micro-organisms and spread diseases.

Answer 1

Mosquitos feed on blood. When they bite they inject some fluids into the site to keep the blood from clotting (and which later cause the itchy hive). Some infections, such as malaria, can get into the mosquito when it drinks the blood of an infected person; the germ migrates to the glands that produce the anticoagulant, and then is injected into the blood of the next person bitten. The mosquito is a vector for many diseases. Malaria, dengue and yellow fever are spread like this by mosquitoes.

Answer 2

Answer:

This means they can transmit diseases from one human or animal to another. Typically, the diseases are caused by viruses or tiny parasites. For example, a mosquito that bites an infected human or animal can pick up a virus along with the blood meal.
