What you need to know about West Nile Virus and Chikungunya

Mosquitoes are more than just an annoyance—they’re capable of transmitting serious diseases, especially in tropical and subtropical regions. Two viruses travelers should be aware of are West Nile Virus (WNV) and Chikungunya. While there are no vaccines or cures for either, the good news is: both are preventable.

West Nile Virus (WNV)

West Nile Virus is primarily transmitted through the bite of an infected mosquito. It’s the leading mosquito-borne disease in the U.S., and though most people don’t develop symptoms, it can occasionally cause severe illness.

Key Facts:

  • Most people show no symptoms

  • 1 in 5 infected individuals may develop fever, fatigue, and body aches

  • Less than 1% develop serious neurological illness, such as meningitis or encephalitis

  • There is no vaccine or antiviral treatment for WNV

Protection is your best defense: Use insect repellent, wear protective clothing, and avoid mosquito-prone areas during peak biting hours (dawn and dusk).

Chikungunya Virus

Chikungunya (pronounced chik-en-gun-ye) is also spread by mosquitoes and causes fever and painful joint swelling. While not usually fatal, it can lead to debilitating symptoms that last for weeks—or longer in some cases.

Symptoms may include:

  • Fever

  • Joint pain

  • Headache

  • Muscle pain

  • Rash

  • Joint swelling

Where It’s Found:

Outbreaks have occurred across Africa, Asia, Europe, and the Americas, including the Caribbean and parts of Central and South America. The virus spreads quickly through infected travelers.

How to Protect Yourself

There is no vaccine or treatment for Chikungunya, so prevention is key. When visiting at-risk regions, the CDC recommends:

  • Using EPA-registered insect repellents

  • Wearing long-sleeved shirts and pants

  • Staying in air-conditioned rooms or screened accommodations

  • Sleeping under mosquito nets if necessary
