Why do mosquitoes don't get the malaria disease when they carry it?


Answer:
Female mosquitos do get infected with the malaria parasites. The parasites embed themselves in her stomach and prevent her from being able to take in enough blood to survive. That is what drives her to bite again and again, because ordinarily once she is full she stops. Instead, the parasites basically are starving her to death. She spreads the disease with each bit, injecting them into her victim- and all the while the parasites are reproducing in her stomach and gut. In the end, she is either killed by a preditor, insecticide, a swat, or she actually dies of starvation. So malaria does infect them and kill them. If you could infect the female mosquitos and prevent them from biting anyone or anything, they would die of it.
THATS A HELLA GOOD QUESTION. LOL.I WOULD HAVE TO BEKUZ THEY HAVE SOME SORT OF IMMUNITY TO IT
malaria is caused by a parasite. mosquitos carry the parasite and transfer it when they stick an individual with their proboscis. it's like a needle and they both draw and push fluids from them to you. the parasite is inside them and is transferred through the proboscis but it does not attack the host (mosquito) since it is in a symbyotic relationship. it feeds on the same blood the mosquito ingests.
Because malaria is a disease affecting human being only. They dont affecct any other animal or insects. Mosquitoes dont carry malaria. They carry bacterias causing malaria. They are just carriers.
It depends on whether the mosquito can carry malaria or not. In Africa they can, and scientists are planning to release mosquitoes who are immune to it so they can spread and suck blood without giving malaria.
The sexual cycle of the parasite is completed in the mosquito. For the asexual cycle, the human host is required. The disease is manifest in this form.
