Bexar County residents are once again being urged to take preventative measures to avoid mosquitoes, including using repellent and pouring out standing water (which attracts them), after mosquitoes carrying the West Nile virus were recently detected in unincorporated Bexar County.

Bexar County Public Works announced on Wednesday they would be increasing mosquito abatement and continue to treat the county with larvicide and adulticide in response to the detection of mosquitoes carrying the West Nile virus, according to a press release. 

Around this time last year, mosquitoes with West Nile were also found in Bexar County, prompting first responders to alert residents by going door-to-door.

According to the Texas Department of State Health Services, there have been 71 confirmed human cases of illness and three deaths caused by the West Nile Virus across the state so far in 2017, though none of them were in Bexar County. In 2016, 370 people became ill and 18 people died from the West Nile Virus across the state.

Rising temperatures and continuous rain create the ideal environment for mosquitoes to inhabit and breed in, and Hurricane Harvey may have played a role in the uptick of mosquitoes. According to the Centers for Disease Control and Prevention, "the types of mosquitoes that can spread viruses may increase 2 weeks to 2 months after a hurricane, especially in areas that did not flood but received more rainfall than usual."
