Outline  Brief introduction to mosquitoes  Diseases mosquitoes can transmit  Why mosquito can’t transmit HIV (AIDS)? Can people get infection from mosquitoes which just access the AIDS patients? Can AIDS virus on mosquitoes’ mouthparts infect people?  Conclusion

Brief introduction to mosquitoes  Larva is wiggler or wriggler. ◦ They live below the surface. ◦ Frequently clear the ponds can stop them reproduce!  Adults are mosquitoes ◦ Male and female mosquitoes feed on nectar/plant juices. ◦ Females mosquitoes are also blood-eating.

Diseases mosquitoes can transmit  Some specific kinds of mosquitoes can transmit disease. ◦ They are called as vector mosquito.  Mosquitoes can transmit dengue fever, malaria, yellow fever and filariasis.  Viruses will be destroyed in mosquitoes’ digestive system if they aren’t in vector mosquitoes.

Why mosquito can not transmit HIV (AIDS)?  Virus needs particular environment to reproduce. (In living body) ◦ HIV virus can’t live in mosquitoes’ digestive system (not vector mosquito).  So the HIV viruses can live in human body, but can’t live in mosquitoes.

Can people get infection from mosquitoes which just access the AIDS patients?  Mouthpart is more complicated than a tube! ◦ Mouthpart have tow tubes.  One will spit saliva. (anticoagulant and anesthesia) ◦ Human can’t feel they are bit.  One will suck blood. ◦ These bloods won’t spit from another tube.  So after biting AIDS patients, mosquitoes won’t spit HIV virus to their next victims.

Can AIDS virus on mosquitoes’ mouthparts infect people?  The blood-sucking mouthparts only take few bloods.  Even though mosquitoes bit AIDS patient, the volume of HIV virus aren’t enough to infect people.  Maybe a person accept one HIV virus after being bitten by 1 million mosquitoes, which they had accessed the AIDS patients.

Conclusion  Mosquito can’t transmit HIV virus/ AIDS!  Vector mosquitoes are still take many diseases to infect human!  Although we don’t need to worry about this possibility, people still need to clear the ponds to kill wigglers.
