The World Health Organization (WHO) has warned of a major chikungunya virus epidemic that could sweep across the globe, calling for urgent action to prevent it. The organization is picking up similar early warning signs as in a major outbreak two decades ago and wants to avoid repeating history.
Chikungunya is a mosquito-borne viral disease that causes fever, severe joint pain, and can be deadly. It has been detected in 119 countries globally, putting over 5.6 billion people at risk. The WHO says the virus is spreading rapidly, with major outbreaks reported in Reunion, Mayotte, and Mauritius since the beginning of 2025.
The symptoms of chikungunya are similar to those of dengue fever and Zika virus disease, making it difficult to diagnose. The virus has also spread to regions such as Madagascar, Somalia, Kenya, and south Asia. In Europe, imported cases have been reported in France and Italy, with local transmission detected in these countries.
The WHO is urging people to protect themselves against mosquito bites by using repellent and not leaving water to stagnate in containers. The tiger mosquito, known for its role in transmitting the virus, is venturing further north due to climate change.
With a low case fatality rate of less than one percent, thousands could be lost to the epidemic if it spreads globally. The WHO is raising the alarm early to prompt countries to prepare and strengthen their capacities to prevent large outbreaks.
