Mosquito biting a human in Louisiana, potentially introducing risk of mosquito borne diseases including West Nile virus

As the humid Louisiana air thickens with the onset of spring and summer, so too does the presence of mosquitoes — and they bring more than just itchy bites. In many parts of the world, mosquitoes are feared as carriers of deadly diseases such as malaria, Zika, and Dengue. Fortunately, here in Louisiana at the time of this writing in 2024, the risk of those mosquito-borne diseases is low, but West Nile virus remains a threat.

Bottom line: if you live in Louisiana in 2024, you shouldn’t worry about the threat of mosquito-borne diseases but you should take it seriously. Let this blog serve as your guide to understanding these risks and learning how to protect yourself and your loved ones.

Do Mosquitoes Transmit West Nile Virus in Louisiana?

Yes, the West Nile virus is indeed a danger in Louisiana, carried by local mosquitoes. While the instances of transmission are sporadic, they are significant enough to warrant precaution. Recently, the Louisiana Department of Health has heightened alerts, advising the public to remain vigilant, especially during peak mosquito seasons. 

Annual reports vary, but in recent years, total cases in Louisiana have ranged from a handful to two hundred, with some cases leading to severe neuroinvasive illnesses. 

Here are some symptoms of West Nile virus to watch for:

  • Fever and headache
  • Body aches and joint pains
  • Rash
  • Fatigue
  • Severe symptoms include neurological effects like encephalitis or meningitis

What’s the Risk of Catching Mosquito-Borne Diseases in Louisiana in 2024?

In Louisiana, the landscape of mosquito-borne threats extends beyond just the West Nile virus. Here’s a closer look at the risks associated with each:

  • Malaria: No malaria cases reported in Louisiana in recent years, though health officials remain concerned after locally transmitted cases were found in Florida and Texas last year.
  • Dengue: Travel-related cases have been reported in Louisiana; no locally transmitted cases.
  • Chagas Disease: Primarily transmitted through triatomine bugs (aka “kissing bugs”), not mosquitoes. Kissing bugs have been found in parts of the United States in recent years, but fortunately no locally transmitted Chagas disease cases.
  • Yellow Fever: Once a historical epidemic, now no longer a threat in the state.
  • Zika Virus: Although there haven’t been locally transmitted cases of Zika in Louisiana, there have been in neighboring states as recently as 2018.
  • Other Mosquito-Borne Diseases: Currently, there aren’t any other mosquito-borne disease threats in Louisiana.

Why Is It Important to Monitor Mosquitoes Even If They Don’t Carry Disease?

Even if an area is free from the risk of mosquito-borne diseases today, it doesn’t mean it will remain that way tomorrow. Ecological conditions change, and animal and disease ranges change with them. 

Louisiana’s warm, humid environment is a perfect breeding ground for mosquitoes, making it a potential candidate for future outbreaks of other tropical diseases. Given the fluctuating number of West Nile cases each year, it is clear that mosquito populations and the diseases they carry can dramatically shift. Therefore, keeping a vigilant eye on local mosquito populations and staying informed through reliable sources like the Louisiana Department of Health is crucial.
