Who is at elevated risk of exposure to Chikungunya virus?

Internal Medicine

Chikungunya virus primarily spreads through infected mosquito bites, so people at higher risk include travelers visiting tropical and subtropical regions where the virus is common, such as parts of Africa, Asia, the Caribbean, Central and South America, and Pacific islands. Outdoor workers, long-term travelers, and those staying in areas with poor mosquito control face increased exposure risk. Pregnant women, older adults, and people with underlying health conditions may experience more severe illness if infected.

If you've recently traveled or been bitten by mosquitoes and are experiencing symptoms like sudden fever, joint pain, rash, or fatigue, don't wait to find answers. A fast, free, and confidential symptom check can help you understand what may be causing your symptoms and guide you on the best next steps—whether that's monitoring at home or seeking medical care. Take a few minutes now to gain clarity and peace of mind.

Explanation

Chikungunya virus is mainly spread by mosquitoes in tropical and subtropical areas. People who travel to these places are at a higher risk of getting the virus.

Who is at Risk?

Travelers: If you visit places where Chikungunya is common, like parts of Africa, Asia, and the Americas, you are more likely to be exposed.
Residents: People living in areas where the virus is already present are also at risk, especially if mosquitoes are common.

Why is Travel a Risk?

Travelers can unknowingly bring the virus to new places. When they return from a trip, they might have the virus in their blood. If a mosquito bites them, it can spread the virus to other people. If you develop symptoms after traveling, use a free symptom checker to help understand what might be causing them.

How to Protect Yourself

Use mosquito repellent.
Wear long sleeves and pants to cover your skin.
Stay in places with air conditioning or screens on windows.

By taking these steps, you can help reduce the risk of getting Chikungunya when traveling.
