Do you think mosquitos cause the (HIV) disease?

Mosquito is not able to transmit the HIV

Never...as the mosquitos do not have the Helper t-cell lymphocyte which is essential for the HIV virus to survive. The HIV virus is very fragile and heat labile and unable to survive for more than 4 minutes when exposed to the atmosphere.

Thanks for your question! 

There are several documented reasons as to why Mosquitoes cannot transmit HIV/AIDS:

1. The blood that mosquitoes ingest does not remain in mosquitoes' mouth is digested. The blood that might remain in its mouth is far too less to contain enough HIV viruses to pose a threat to someone.

2. Mosquito is  not a fit enough host in which a virus persist. Any HIV virus in the blood sucked by the mosquito will wither and die.

3. Mosquitoes need time to digest the blood they have sucked. The HIV dies 4 to 5 hours without a host, during which the mosquitoes might not bite someone.

4. The gradient( titer concentration) of HIV virus ingested by the mosquito is too less for the virus to be potent given that the highly unlikely event of mosquito transmitting the virus happens.

So the possibility of HIV/AIDS being spread through a mosquito is nil to none. Moreover, the above points have been verified by hundreds of independent researches. [1]
