Officials along with local municipalities are continuing to monitor and conduct mosquito surveillance. As of right now mosquito samples that have been sent to the Texas DSHS laboratory in Austin have been tested and returned negative, according to a county news release.

County health officials want residents to take precautions like wearing long-sleeved clothing and using EPA-approved mosquito repellent. Officials are encouraging residents to apply these precautions at all times whether traveling locally, statewide or abroad.

In order to help limit mosquito breeding, officials are asking residents to remove standing water from buckets, unused pools and tires after recent rains. They recommend placing mosquito dunks to prevent mosquito larvae from maturing in water sources that cannot be drained.

County officials are also encouraging healthcare providers to order an arboviral panel for patients who are exhibiting symptoms associated with arboviral illness. They recommend an arboviral panel include screening for West Nile virus, Saint Louis encephalitis and Dengue virus.
