Zika virus – Incidence and trends
To date, 40 countries and territories have confirmed local, vector-borne transmission of Zika virus disease in the Region of the Americas since 2015. In addition, five countries in the Americas have reported sexually transmitted Zika cases (Argentina, Canada, Chile, Peru, and the United States of America). Since the last Pan American Health Organization/ World Health Organization (PAHO/WHO) Zika Epidemiological Update on 7 July 2016, no additional countries or territories have confirmed vector-borne autochthonous transmission of Zika virus (Figure 1).
In the past week, Canada reported 143 travel-related Zika cases detected in 2015 and 2016 (as of 6 July) to PAHO/WHO. Of these, 142 cases acquired the infection in countries/territories of the Americas.
In the United States, a confirmed–imported–case of Zika died in the state of Utah becoming the first confirmed Zika related death in the continental United States.
In the last four weeks of reported data, an increasing trend in cases has been observed in Costa Rica, Ecuador, Guadeloupe, Guatemala, Jamaica, Mexico, Nicaragua, Puerto Rico, Saint Barthelemy, Saint Martin, and Venezuela.
