What other diseases besides malaria, dengue fever etc. do mosquitoes transmit?

Question: When the female mosquito bites a person, she draws blood.people who have swatted mosquitoes discover they are loaded with blood.Now if a female mosquito bites Jamie and he has TB,AIDS, Herpes etc then it bites Susie and releases some blood into her blood stream, what are the chances of her being ill?The disease is in a person's blood stream otherwise a blood test would not be able to determine a disease or infection.In addition, when a mosquito bites, they all look alike so it is difficult to tell if it is a female anopholes or female dengue fever or west nile virus carrier..Also,doctors say AIDS is sexually transmitted but patients have died from the diease after a blood transfusion of tainted blood.

Answers:
There are other diseases that mosquitos transmit, but TB, AIDS, and Herpes are not among them.

When the mosquito "bites" she injects a certain saliva under the skin to prevent clotting the blood. If the blood clotted, it would clog her feeding tube. After taking her blood meal, her feeding tube is wiped clean of blood and she rests for a few hours to digest it, thereby allowing germs on the tube to die.

Malaria, dengue fever, and west nile are carried because they actually develop inside the mosquito. The parasite Plasmodium (for malaria) has a host inside the human, and another host inside the mosquito. (I can send you the whole biology chapter if you want it.) The parasite develops inside the mosquito and is then sent to the salivary glands, where it is passed on to the next human in that saliva -- about 8 hours after biting the first malaria-infected human.

At this time, AIDS has not developed into a disease that can use mosquitos as hosts. It can be sexually transmitted, because there are virus cells in the reproductive fluids and there are always small abrasions made during a sexual act which allows these virus cells to pass into the blood stream. It can be transmitted by blood transfusion, or by using an injection needle more than one as is common among stoned drug users.

However, AIDS does not (yet) have the ability in its life cycle to develop inside a mosquito and migrate to the salivary glands so as to infect the next person. It is unlikely that it will, because it is a virus and not a living parasite; also it is a mammalian disease and would have no effect on insect cells. If AIDS were passed by mosquitos, using the number of malaria infections every year and the impossiblity of buy medication for either disease, everyone in Africa would have been dead for almost a century as the disease passed.

I hope that this answers some of your questions, and the implied worry, about the possible diseases passed by the mosquitos. If you want more information just contact me!

They transmit plague. But it doesnt come from them. It comes from rats to mosquitoes to humans.
