Can Mosquitoes Transmit Hiv

  1. 1. Dr. Sujnanendra Mishra, MD
  2. 2. Dr.Sujnanendra Mishra
  3. 3. <ul><li>During a bite, the mosquito injects saliva into your blood. This keeps your blood liquid, and easy for the mosquito to take. </li></ul><ul><li>The mosquito sucks, and leaves. Any mosquito saliva left is all that could contain a possible HIV particle. It looks like a mosquito does not transfer much from “meal to meal”. </li></ul>Dr.Sujnanendra Mishra HIV particles would have to somehow get into the saliva of the mosquito, and then be transferred to a new person.
  4. 4. <ul><li>There are THREE hypothetical situations which would allow mosquitoes to transmit HIV. 1.First , a mosquito would initiate the cycle by feeding on an HIV positive carrier and bite a non-infected person , 2. Second , a mosquito after partial feed on an HIV carrier and completes blood meal on a different individual. 3. Third, Squishing a mosquito on a open wound carrying HIV particle . </li></ul>Dr.Sujnanendra Mishra
  5. 5. Dr.Sujnanendra Mishra Since the virus never survive to reproduce and to invade the salivary glands, the mechanism that most mosquito-borne parasites use to get from one host to the next is not possible with HIV. <ul><li>INFECTING AGENTS </li></ul><ul><li>SURVIVAL PERIOD inside mosquito </li></ul><ul><li>Malaria parasites </li></ul><ul><li>9-12 days and actually go through a series of necessary life stages during that period. </li></ul><ul><li>Encephalitis virus </li></ul><ul><li>10-25 days inside a mosquito and replicate enormously during the incubation period. </li></ul><ul><li>HIV- </li></ul><ul><li>1-2 days and completely destroy any virus particles that could potentially produce a new infection. </li></ul>
  6. 6. <ul><li>The food canal and salivary canal are separate ways in the mosquito. The mosquito's feeding apparatus is an extremely complicated structure that is totally unlike the crude single-bore syringe. Unlike a syringe, the mosquito delivers salivary fluid through one passage and draws blood up another. </li></ul>Dr.Sujnanendra Mishra Food canal and salivary canal are not the same..
  7. 7. <ul><li>The mechanics involved in mosquito feeding are totally unlike the mechanisms employed by the drug user's needles. In short, mosquitoes are not flying hypodermic needles and a mosquito that disgorges saliva into your body is not flushing out the remnants of its last blood meal. </li></ul>Dr.Sujnanendra Mishra
  8. 8. <ul><li>HIV circulates at very low levels in the blood--. Infected individuals rarely circulate more that 10 units of HIV, and 70 to 80% of HIV-infected persons have undetectable levels of virus particles in their blood. Crushing a fully engorged mosquito containing AIDS positive blood would still not begin to approach the levels needed to initiate infection. </li></ul>Dr.Sujnanendra Mishra Ingested blood contains suboptimal level of HIV particle. Many of them might have been digested at the time of crushing.
  9. 9. When you account for each step, the odds are extremely minimal of getting AIDS from a mosquito. So, you really don't have to worry about getting AIDS from a mosquito bite. If you're still worried, remember that not one case has ever been documented. Dr.Sujnanendra Mishra
