when a disease get transported by a transporter like mosquito , why don't the transporter get the disease?
Mosquito is a carrier of the disease.Once infected by a mosquito bite, the reservoir species are usually not seriously affected. They will, at least for a time, produce enough virus in their bodies to infect mosquitoes. In this manner, mosquitoes pick up the virus and may become vectors, or organisms that transmit the disease to other animals, such as birds, horses or humans.Mosquitoes do not actually "bite" humans; they "feed" on them. Female mosquitoes require protein to produce their eggs and obtain this protein from the blood of humans and other animals.The diseases are often viruses that are picked up by the mosquito when it feeds on an infected host. When the mosquito then feeds on another host, it can then spread the virus.
