Can You Get HIV From a Mosquito? What You Should Know

If you love spending time outside in the summer and are vigilant about your health, maybe you’ve wondered, “Can you get HIV from a mosquito?”

As a trusted source of mosquito control in NJ, Nada Mosquito offers the following knowledge about the dangers of mosquitos, including what diseases you can catch from mosquito bites.

How HIV Spreads

While mosquitoes are notorious for transmitting diseases, they cannot transmit HIV. You catch HIV by blood-to-blood exchange, such as transfusion or from a tainted needle.

While it might seem like that happens when a mosquito bites you, it’s not true. The mosquito’s bite actually has two tubes, one for injecting an anti-coagulant that allows for more efficient feeding and another that sucks up your blood. Even if the mosquito recently fed on a person positive for HIV, that blood would never come in contact with yours.

Furthermore, contrary to popular belief, you can’t catch HIV from exchanging saliva, such as from kissing or an insect bite. Mosquitos also don’t have the immune cell receptors required to catch HIV.

What Diseases Can a Mosquito Transmit?

So, can you get HIV from a mosquito? No, but other mosquito-borne diseases can pose a legitimate threat to your health.


This illness doesn’t result in death, but it can cause chronic pain. It’s most common in Africa and Asia, and cases in the United States usually only occur in people returning from overseas travel.

Dengue Fever

More severe cases of dengue fever can cause severe bleeding and even death. Scientists are on the cusp of curing the disease and think the mosquito gut’s microbiome may hold the answers.


A mosquito bite can transmit several different forms of encephalitis, depending on the area of the world and the type of mosquito. The most common forms of encephalitis from mosquitos include:

  • Eastern equine encephalitis
  • Japanese encephalitis
  • La Crosse encephalitis
  • St. Louis encephalitis
  • Venezuela encephalitis

Lymphatic Filariasis

Also known as elephantiasis, many cases of this illness don’t have any symptoms. When symptoms present, it results in disfigurement and disability from extremely swollen limbs.


Malaria is one of the most notorious diseases spread by mosquitos, and the more than half a million people who die from the disease every year make the mosquito the most deadly creature on earth. Because of the medical care and medications available in the United States, the CDC has considered malaria eradicated in the country since 1951.

Other Diseases

Other common mosquito-borne diseases include:

  • West Nile fever
  • Zika fever
  • Yellow fever
