The World Health Organization (WHO) has issued an urgent call for global action to prevent a repeat of the chikungunya virus epidemic that occurred two decades ago. The mosquito-borne virus, known for causing intense and prolonged joint pain, is currently spreading with new outbreaks linked to the Indian Ocean region and extending to Europe, other continents, and southern China. China, including Macau, has reported over 3,000 cases, contributing to tens of thousands of cases worldwide. WHO warns that the virus poses a global risk of epidemic resurgence and urges immediate preventive measures. The organization highlights the need for coordinated efforts to contain the spread and mitigate the impact of this disease.
