SUMMARY

 From 1 January 2007 to 23 March 2016, Zika virus transmission was documented in a total of 61 countries and territories. Four of these countries and territories reported a Zika virus outbreak that is now over. Argentina and New Zealand are the latest countries to report sexual transmission of Zika virus. Thus, five countries have now reported locally acquired infection in the absence of any known mosquito vectors, probably through sexual transmission (Argentina, France, Italy, New Zealand and the United States of America).
