Epidemiological alert Chikungunya – 10 February 2026|10 Feb 2026 |Pan American Health Organization

Although the observed dynamics may correspond to expected epidemiological patterns in contexts where the vector is present, the reappearance of cases in certain territories reinforces the need for sensitive surveillance and a timely response. In this context, the Pan American Health Organization/World Health Organization (PAHO/WHO) urges Member States to intensify epidemiological and laboratory surveillance, ensure early detection and appropriate clinical management of cases, and consolidate integrated vector control actions in order to limit transmission and reduce associated morbidity and mortality.
