Raises travel advisory for Brazil and Reunion Islands due to chikungunya outbreak
Large chikungunya outbreaks are currently ongoing in Brazil, Réunion Island, and several other countries, as reported by health authorities. The disease, primarily spread through the bite of infected Aedes mosquitoes, has caused significant concern worldwide, with over 250,000 cases reported globally so far in 2025.
In the Americas, Brazil is experiencing the largest outbreak, reporting 176,391 cases as of mid-2025. The country is followed by Bolivia with 3,863 cases and Argentina with 2,817 cases. These numbers represent part of over 183,000 cases reported across 11 countries in the Americas.
The Indian Ocean region, particularly Réunion Island, has seen a large outbreak where an estimated one-third of the population has been infected. Other islands affected include Mayotte and Mauritius. In Asia, notable numbers of cases have been reported in India, Sri Lanka, Pakistan, and Southeast Asian countries such as Indonesia and the Philippines.
Regions previously free of local chikungunya transmission, including southern Europe, have started reporting occasional local cases, attributed to climate change facilitating mosquito breeding.
The Centers for Disease Control (CDC) has raised its travel alert for Brazil and Réunion Island to Level 2, advising travelers to exercise increased caution. Level 1 alerts apply to other affected countries in Asia and the Americas.
Mosquito control efforts, health system strengthening, public education, and travel advisories are critical strategies to mitigate the spread and impact of the disease. Health authorities emphasize the importance of mosquito control, including surveillance, elimination of breeding sites, and use of insecticides. Rapid detection, diagnosis, and clinical management of chikungunya cases are also crucial. Public education campaigns promote personal protection such as use of mosquito repellents, wearing long sleeves, sleeping under mosquito nets, and avoiding outdoor exposure during mosquito activity times.
In light of the ongoing outbreaks, support for vaccine development and research is encouraged to better control outbreaks in the future. The World Health Organization (WHO) has issued urgent calls to action to control the spread and prevent further infections.
A summary table of key affected areas and alerts is provided below:
