Brazil on 11 May, 2017 declared an end to public health emergency for the Zika Virus after about 18 months of fight against this mosquito borne virus. The Zika Virus emergency fell up on Brazil when the country was preparing to host the 2016 Olympics, fueling the concerns that Rio Olympics could spread the Virus. In November 2016, the World Health Organization (WHO) lifted its own international health emergency status for Zika.
