DALLAS (AP) — Communities across North Texas are boosting efforts to educate people about the West Nile virus. This comes as health officials await results of aerial spraying on a mosquito population that has put Texas at the center of a nationwide outbreak.

Workers in Dallas are passing through neighborhoods to hand out educational materials, drain standing water and apply larvicide to puddles. Other communities are providing tablets to kill mosquito larvae, and using automated phone messages and social media to spread the word.

The strategies were implemented this summer as the virus has infected hundreds of people and killed more than 20 others across Texas. The Dallas County area has been the hardest hit, with about 300 falling ill.

Officials have not ruled out doing more aerial spraying.
