WHO Warns of Potential Chikungunya Resurgence Like 2005 Epidemic

 WHO Issues Urgent Warning: Chikungunya Outbreak Risks Repeating 2005 Epidemic

GENEVA — The World Health Organization (WHO) has sounded the alarm, cautioning that the world could face a chikungunya resurgence akin to the devastating 2005 epidemic unless immediate steps are taken to curb its spread. Chikungunya, a lesser-known mosquito-borne virus, is already present in 119 countries, putting 5.6 billion people at risk, according to Diana Rojas Alvarez, WHO’s arbovirus team lead, during a recent UN briefing.

Symptoms and Spread of Chikungunya

This virus triggers fever, rash, and intense joint pain that can persist for weeks or result in chronic disabilities for up to 40% of those affected. Since early 2025, significant outbreaks have struck Indian Ocean islands such as La Reunion, Mayotte, and Mauritius, with an estimated one-third of La Reunion’s population impacted, Rojas noted. The virus is now extending its reach into Madagascar, Somalia, and Kenya, while South Asia continues to grapple with outbreaks following India’s 2024 epidemic.

Rising Cases and Global Concern

Sri Lanka and Bangladesh are experiencing a surge in infections, and Europe has seen imported cases, including local transmission in France and potential cases in Italy. Rojas highlighted that this pattern echoes the 2004–2005 outbreak, urging swift action to prevent history from repeating itself.

Prevention and Control Measures 

Rojas stressed the need for enhanced surveillance and mosquito control in regions where Aedes mosquitoes thrive. Although case numbers are dipping with winter setting in across the Indian Ocean, she underscored the importance of early detection and quick response to minimize infections and reduce long-term health and economic impacts.

WHO’s Support Efforts

The WHO is stepping up by sending experts, training healthcare professionals, and backing vector control initiatives to help affected nations combat the virus effectively.

Why This Matters

As chikungunya spreads globally, understanding its impact and the WHO’s response is crucial for public health preparedness.
