The World Health Organization (WHO) has raised a global alert over the resurgence of the Chikungunya virus, a mosquito-borne illness that is rapidly spreading in various parts of the world, including Europe. Once largely contained to tropical and subtropical regions, the virus is now making inroads into new territories due to rising global temperatures and increased urbanization, which have expanded mosquito habitats.
Chikungunya is transmitted primarily by Aedes aegypti and Aedes albopictus mosquitoes—the same vectors responsible for dengue and Zika. It causes a sudden onset of high fever, severe joint pain, fatigue, headache, and rash. While the infection is rarely fatal, the joint pain can be long-lasting and debilitating, especially in older adults or those with underlying conditions.
WHO has urged countries to intensify mosquito-control efforts and educate the public about preventive measures. These include using insect repellent, wearing long-sleeved clothing, and eliminating stagnant water sources around homes and public spaces. The agency is also calling for more investment in vaccine development, as there is currently no specific treatment or approved vaccine for Chikungunya.
The renewed outbreak has put health authorities on high alert, especially as the Northern Hemisphere enters peak mosquito season. With global travel returning to pre-pandemic levels, the risk of cross-border transmission is higher than ever. Governments and individuals alike are being encouraged to remain vigilant.
The WHO’s warning serves as a stark reminder that climate-sensitive diseases like Chikungunya are not just regional concerns—they are a global public health challenge demanding urgent action.
