If you live in Jacksonville, you know mosquitoes bite, and you probably know that mosquitoes can spread dangerous diseases. But you might be wondering how many diseases they can carry, how often you need to be bitten to get sick, or how worried you should be.

t isn’t enough to know that an insect can be dangerous. You need details. Today, we’re going to take a look at a few facts every Jacksonville resident should know about mosquito disease transmission and take a quick look at diseases caused by mosquitoes.

How Do Mosquitoes Get Malaria & Other Diseases?

You know that not every mosquito that bites you is infected with a disease. It is possible to get bitten numerous times and not get sick. What makes one mosquito more dangerous than another? And how worried should you be about mosquito-borne diseases?

Here are a few important factors to consider:

  • Not all mosquitoes carry all diseases. The mosquitoes that spread malaria are Anopheles mosquitoes. Culex mosquitoes spread West Nile virus. Aedes mosquitoes spread Zika virus, dengue fever, chikungunya, and yellow fever. There are actually apps available for your smartphone that can help you identify dangerous mosquito species by the sounds they make.
  • Mosquitoes aren’t born with diseases. They catch them. How do mosquitoes get malaria, West Nile virus, Zika virus, and other diseases? They bite an infected person or animal. The mosquitoes that are the most threat to human health are mosquitoes that pick diseases up from animals in our local population. This is why West Nile virus is so common in Jacksonville. Consequently, it is also why West Nile virus is such a threat.
  • It is possible to get bitten by an infected mosquito and not get sick. Your body may fight the virus and you may only experience minor symptoms. It is also possible to be asymptomatic, which means you carry a disease without showing any symptoms at all.
  • The risk of dangerous mosquito-borne viruses, such as malaria, Zika, and yellow fever, increases when travelers bring these viruses into the state and we have an outbreak. Watch for news of outbreaks to know when to take greater precautions against mosquitoes.
  • People who have an undeveloped or compromised immune system are at greater risk of serious illness.

List Of Diseases Caused By Mosquitoes

Now that you know a little bit about how mosquitoes in Jacksonville can make you sick and how likely it is that you’ll be exposed to viruses, let’s take a specific look at the diseases caused by mosquitoes.

West Nile Virus

This is considered to be the most common mosquito disease in the United States. It is associated with brain swelling, which has the potential to be fatal. Recent figures put the number of cases at 664, with 52 deaths occurring. Out of a population of more than 329 million people, your odds of dying from this are very low.

EEE Virus

Eastern equine encephalitis is a virus that attacks the nervous system and can also cause brain swelling. While extremely rare, some cases do appear in Eastern and Gulf Coast states each year.


This disease is a worldwide epidemic that impacts half of the world’s population. While significant measures have been taken to reduce the number of deaths related to this disease, 409,000 deaths were reported in 2019. That is down from over 1 million. But it is still a scary figure to consider.

Zika Virus

We recently had a big scare with this disease. The Zika virus can be a threat to adults, but it is its threat to unborn children that makes it a serious medical concern. This disease can result in microcephaly, a condition in which a baby’s head is much smaller than it should be. A birth defect like this can have a lifelong impact on a family.

Dengue Fever & Yellow Fever

Dengue fever and yellow fever are serious diseases that can spread during outbreaks. They come with flu-like symptoms that can elevate to a serious, life-threatening level. Dengue fever is often called “breakbone fever” because of the pain associated with it. Yellow fever can also be painful as there is muscle pain involved, but it is the fact that this is a hemorrhagic disease that is of most concern. Victims of yellow fever can experience bruising and internal bleeding.
