Health Workers Test And Spray For Mosquitos As Texas Prepares For Zika Virus

MCALLEN, TX - APRIL 14: Environmental health specialist Aaron Salazar prepares to check a mosquito trap on April 14, 2016 in McAllen, Texas. City workers are catching mosquitos and sending them to labs to test for Zika and other mosquito-borne diseases. Health departments, especially in areas along the Texas-Mexico border, are preparing for the expected arrival of the Zika Virus, carried by the aegypti mosquito, which is endemic to the region. The U.S. Centers for Disease Control (CDC), announced this week that Zika is the definitive cause of birth defects seen in Brazil and other countries affected by the outbreak.
