  • The World Health Organization (WHO) and partners established a definition of what constitutes an outbreak, endemic transmission, and the interruption of mosquito-borne transmission in order to better characterize the level of transmission of Zika virus infection (Table 1, Fig. 2). This classification system was put into use as of the situation report of 7 July 2016.

Summary

WHO and partners established a definition of what constitutes an outbreak, endemic transmission, and the interruption of mosquito-borne transmission in order to better characterize the level of transmission of Zika virus infection (Table 1, Fig. 2). This classification system was put into use as of the situation report of 7 July 2016.

08 Jul 2016 description

To date, 40 countries and territories have confirmed local, vectorial transmission of Zika virus disease in the Region of the Americas since 2015 (Figure 1). In addition, five countries in the Americas have reported Zika cases by sexual transmission (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 30 June 2016, no additional countries or territories confirmed vector-borne autochthonous transmission of Zika virus.

Summary

  • WHO and partners have established a definition of what constitutes an outbreak, endemic transmission, and the interruption of vector-borne transmission in order to better characterize the level of transmission of Zika virus infection (Table 1, Fig. 2). In addition, this will facilitate public health recommendations for residents and travellers. Based on these definitions, countries and territories reporting mosquito-borne Zika virus transmission were reclassified.
