ABSTRACT
Background: Climate extremes will increase the frequency and severity of natural disasters worldwide. Climate-related natural disasters were anticipated to affect 375 million people in 2015, more than 50% greater than the yearly average in the previous decade. To inform surgical assistance preparedness, we estimated the number of surgical procedures needed.

As of 3 August 2016, 68 countries and territories (Fig. 1, Table 1) have reported evidence of mosquito-borne Zika virus transmission since 2007 (65 of these countries and territories have reported evidence of mosquito-borne Zika virus transmission since 2015):

 51 countries and territories with a first reported outbreak from 2015 onwards (Table 1).

 Four countries are classified as having possible endemic transmission or have reported evidence of local mosquito-borne Zika infections in 2016.

28 Jul 2016 description

 As of 27 July 2016, 67 countries and territories have reported evidence of mosquito-borne Zika virus transmission since 2007 (64 of these countries and territories have reported evidence of mosquito-borne Zika virus transmission since 2015):

 50 countries and territories with a first reported outbreak from 2015 onwards.

22 Jul 2016 description
  • 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.

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.
