Which Mosquitoes Can Transmit Disease?

Three main species of mosquitoes—Aedes, Culex, and Anopheles—are responsible for transmitting diseases, with numerous subtypes within each group. Fortunately, many mosquito species are mere annoyances and do not transmit diseases.

What Diseases Do Mosquitoes Carry in the U.S.?

The United States hosts over 200 mosquito species, among which approximately 12 are capable of transmitting diseases. Instances of Dengue fever, chikungunya, Zika virus, and malaria have been reported in regions including Florida, Texas, Puerto Rico, Hawaii, and the US Virgin Islands. However, most malaria cases stem from travelers returning from tropical areas. The majority of mosquitoes encountered locally are nuisance species that do not transmit diseases.

Symptoms of Mosquito-Borne Disease

While bites from nuisance mosquitoes typically yield mild symptoms, certain signs may indicate a more serious condition. Symptoms associated with vector-borne diseases include:

  • Sudden high fever
  • Stiff neck
  • Confusion
  • Nausea or vomiting
  • Muscle tremors or seizures
  • Severe headaches
  • Rash

If you notice any of these symptoms following a suspected mosquito bite promptly get medical attention at your nearest hospital.
