2015–16 Zika virus epidemic

Brazil warned pregnant women on Feb. 1 to stay away from the Summer Olympics after the World Health Organization (WHO) declared an international emergency over the Zika virus, blamed for causing a surge in brain-damaged babies.

The World Health Organization (WHO) Director-General Margaret Chan declared on Monday that the Zika virus constitutes a Public Health Emergency of International Concern.

Chan had convened an Emergency Committee to collect advice on the severity of the health threat associated with the continuing spread of Zika virus disease in Latin America and the Caribbean.

The Dominican Republic said on Jan. 23 that it has 10 confirmed cases of the mosquito-borne Zika virus, the ailment suspected of causing serious birth defects in newborns.

Altagracia Guzman, the Caribbean country's health minister, said lab testing of samples sent to the United States had confirmed Zika in 10 out of 27 suspected cases.
