What is Chikungunya Virus?

The Chikungunya Virus is a mosquito-borne infection caused by the Aedes aegypti and Aedes albopictus mosquitoes.

It spreads quickly in tropical and subtropical regions and causes severe joint pain, fever, and fatigue.

In recent years, travel-related cases have appeared in the United States, especially in southern states during summer.

Origin and History of Chikungunya Virus

Discovery and First Outbreaks

The virus was first discovered in 1952 in Tanzania, Africa.

How Does Chikungunya Spread?

Chikungunya spreads when an infected Aedes mosquito bites a healthy person.

These mosquitoes usually bite during the day, unlike malaria-carrying mosquitoes that bite at night.
The virus does not spread directly from person to person, only through mosquito bites.

High-Risk Situations

• Living near stagnant water

• Traveling to tropical countries

• Not using mosquito repellents

Global Impact and USA Connection

Though most cases occur in Africa and Asia, the USA has seen rising imported cases from travelers.
Warmer climates and increased global travel have made mosquito-borne viruses a growing concern in 2025.

According to CDC, over 400 travel-related Chikungunya cases were reported in the USA in the last year.
