What Diseases Do Mosquitoes Spread?
Mosquitoes have been called the most dangerous insect due to the diseases they are able to spread. Every year worldwide, there are more than 700,000 deaths from vector-borne diseases. These diseases have disproportionately affected populations in tropical and subtropical regions, but are a global threat. The diseases mosquitoes are responsible for spreading include:
- Chagas disease
- Yellow fever
- Zika virus
- Rift Valley fever
- West Nile virus
Do All Mosquitoes Transmit Disease?
There are thousands of mosquito species, but not all transmit disease. The three species of mosquitoes that are responsible for spreading diseases are Aedes, Culex, and Anopheles mosquitoes. There are multiple species within these families. Thankfully, there are many types of mosquitoes that are not responsible for transmitting disease and are primarily a nuisance pest. Here in Eastern Tennessee, we have had reported cases of the Aedes and Culex mosquitoes.
