Mosquitoes are known for spreading diseases, but which diseases do mosquitoes spread in Tennessee?

What Mosquitoes Transmit Disease in Bristol and Johnson City?

Out of the many types of mosquitoes, three mosquitoes are known to spread disease: 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 Bristol and Johnson City, we have had reported cases of Aedes, Culex, and Anopheles mosquitoes. While the diseases they spread are rare here, it’s still a threat.

What Diseases Do Mosquitoes Carry?

More than 200 types of mosquitoes are found in our nation. Of those, only about 12 types are capable of transmitting disease. The diseases that have been found in the United States include Dengue, chikungunya, Zika virus, and Malaria; these outbreaks occurred in Florida, Texas, Puerto Rico, Hawaii, and the US Virgin Islands. Most cases of malaria reported occur in returned travelers from tropical regions. Most types of mosquitoes we encounter are nuisance mosquitoes that are incapable of transmitting the diseases that make people sick.

Mosquito-Borne Disease Symptoms

If you are bitten by a mosquito, your mild symptoms will typically subside in just a day or two. So what symptoms alert you that you may be suffering from something more serious? Common symptoms of vector-borne diseases include:

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

Do Mosquitoes Spread Malaria in Tennessee?

With recent news of mosquitoes transmitting malaria in Florida, many people want to know if the same thing is possible here in Tennessee. The short answer is that, yes, it is possible. As of right now, it’s highly unlikely, but the Asian tiger mosquito, the dominant species of mosquito here, is a known carrier of malaria.

Malaria has been afflicting humans for centuries. Hundreds of years ago, it was quite common in North America, but malaria-carrying mosquitoes were eliminated here. Outbreaks can always pop up with little warning, however, which is why the best policy is to keep your property as free of mosquitoes as possible, and to keep up with the latest news.
