Mosquitoes are notorious for spreading serious diseases around the world. Each year, vector-borne illnesses cause over 700,000 deaths globally. While tropical and subtropical regions bear the brunt of these impacts, mosquito-borne diseases remain a worldwide concern. The most common ones include:
Out of more than 200 mosquito species in the U.S., only about a dozen are known to spread disease. These disease-carrying mosquitoes are mostly active in places like Florida, Texas, Puerto Rico, Hawaii, and the U.S. Virgin Islands. Most malaria cases here are linked to travel abroad. The majority of mosquitoes Americans encounter are simply a nuisance and don’t pose a health threat.
The primary culprits behind mosquito-borne diseases are three major groups: Aedes, Culex, and Anopheles mosquitoes. Each of these groups contains several species, many of which are capable of transmitting serious illnesses like dengue, West Nile virus, and malaria. Understanding which species are active in your area can help guide effective prevention and control efforts.
Bites from common mosquito species usually cause only mild irritation, but certain symptoms can signal a more serious health issue. Watch for these signs, which are commonly associated with vector-borne diseases:
Should you notice any of these symptoms from a mosquito bite, it’s crucial to head to the hospital immediately.

Mosquitoes are widely known for spreading serious diseases, yet they cannot pass on HIV or AIDS. They transmit illnesses acquired through bites from infected humans or animals. Here’s why mosquitoes cannot transmit HIV:
While mosquitoes feed on blood, they don’t transfer it back into their hosts due to their unique proboscis design. Their proboscis consists of two tubes: one for delivering saliva and the other for drawing blood. This mechanism is why mosquitoes can’t transmit HIV, as the virus is carried in the blood, and they don’t transfer it to other hosts.
When a mosquito feeds on an HIV-positive individual, the virus is gone within one to two days, the time it takes the mosquito to digest the blood. Unlike in humans, where HIV binds to T cells, the mosquito’s digestive system cannot support the replication of HIV. As a result, any HIV in the blood is fully destroyed during digestion.
In short, there’s no reason to fear HIV transmission from mosquitoes. Studies confirm that for even a small amount of HIV to be transmitted, an individual would have to be bitten by 10 million mosquitoes that had all fed on an infected person. The key concern should be the vector-borne diseases that mosquitoes are capable of spreading.
