Boston officials urged residents to protect themselves from the virus by using insect repellant, wearing long sleeves, and emptying standing water.

"We're trying to look at all types of mosquitoes out there", said Texas Department of State Health Services (DSHS) regional medical director for South Texas Dr. Emilie Prot. Since 2002, there have been 64 confirmed cases in humans in the county - two of which were fatal.
