Because of concerns about the Zika risk in an area of Texas where dengue outbreaks have occurred before, Texas state health officials urged medical providers to test pregnant women in six counties for the virus if they have symptoms, regardless of travel history.
In other developments, Brazilian researchers who profiled 11 babies with Zika-linked microcephaly found a wide scope of problems, tests on macaques shed more light on how the virus might behave in humans, and Florida reported 6 more locally acquired Zika cases.
The Texas Department of State Health Services (TDSHS) said no local cases have been reported from Texas, but there’s a chance Zika could follow in the footsteps of past dengue outbreaks, since both are spread by the same Aedes aegypti mosquitoes. Its alert to providers involves Cameron, Hildago, Starr, Webb, Willacy, and Zapata counties. All are on Texas’ southern tip on the border with Mexico, where Zika is already circulating.
