Zika Virus Infection in Texas (USA) (Update)

13 Dec 2016

As of 9 December 2016 the Texas Department of State Health Services has identified four additional cases of suspected locally acquired Zika virus (ZIKV) infection in Cameron County. These cases where identified during the follow up to the states first locally acquired ZIKV case reported on 28 November 2016.

All four additional cases live in close proximity to the first case, none are pregnant women and all reported ZIKV symptoms between 29 November to 1 December 2016.  These ZIKV infections were therefore likely to have been acquired in local area before mosquito control efforts intensified in that part of Brownsville.

Please refer to the Health Protection Scotland ZIKV transmission table to determine the current risk category of any given country/territory/area:
