4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.
