According to WHOβs latest global situation report on chikungunya (Disease Outbreak News, 3 October 2025), 445,271 suspected and confirmed cases and 155 deaths were recorded worldwide across 40 countries between 1 January and 30 September 2025.
While the South-East Asia Region (which includes India) recorded fewer cases than in 2024, other regions, particularly the Americas and parts of Africa saw sharp increases.. The report warns that infected travellers and expanding mosquito habitats could introduce the virus into new regions with susceptible populations.
Key drivers include climate change, urbanisation, low population immunity, and weak vector-control and diagnostic systems.
The report underscores that vector-borne diseases are re-emerging as climate-linked global threats. For India and similar tropical countries, it reinforces the need for predictive vector mapping, integrated surveillance for chikungunya-dengue-Zika, and community-based prevention within national health-security frameworks.
What is Chikungunya? β A mosquito-borne viral disease spread by Aedes mosquitoes (the same that transmit dengue). It causes sudden fever and severe joint pain, sometimes lasting months. While rarely fatal, it can cause long-term disability and burden health systems during outbreaks.
