On 26 November 2015, national health authorities in Mexico notified PAHO/WHO of 3 cases of Zika virus infection, including two autochthonous cases (residents of Nuevo León and Chiapas) and one imported case (with history of travel to Colombia). The diagnoses were made by the national reference laboratory using reverse transcription polymerase chain reaction (RT-PCR). Mexican health authorities are implementing the corresponding prevention and control measures. Investigations are ongoing.

WHO advice

Given the increased transmission of Zika virus in the Region of the Americas, PAHO/WHO recommends that its Member States establish and maintain the capacity to detect and confirm cases of Zika virus infection, prepare their health services for a potential additional burden at all levels of health care, and implement an effective public communications strategy to reduce the mosquitoes that transmit this disease, particularly in areas where this vector is present. The complete set of recommendations is available in the latest Epidemiological Update (see related links).
