Health authorities have expressed concern about a noticeable increase in the spread of the Chikungunya virus in the Colombo and Kotte areas, following several years of low transmission.

Medical experts emphasize that eliminating mosquito breeding sites is the most effective way to control the spread of the virus.

Chikungunya, transmitted to humans through the bite of an infected mosquito, has been identified in regions across Africa, the Americas, Europe, Asia, and islands in the Pacific and Indian Oceans. Authorities also highlight the risk of the disease spreading to unaffected areas via infected travelers.

Sri Lanka is currently experiencing a re-emergence of Chikungunya, particularly in urban zones. With school holidays underway, children are more exposed to outdoor environments, and recent rainfall may contribute to an increase in mosquito density. As a result, the public is urged to stay vigilant, eliminate mosquito breeding sites, and keep their surroundings clean to prevent further spread.

According to the World Health Organization, common symptoms of Chikungunya include sudden fever onset, joint pain (often severe, affecting the hands and feet), muscle pain, headache, nausea, fatigue, and rash. Symptoms typically appear four to eight days after a mosquito bite, though they can range from two to 12 days. Most patients recover fully, though joint pain may persist for weeks or months in some cases. While Chikungunya is rarely fatal, it can be more severe in older adults, newborns, and individuals with underlying health conditions.
