Effect of aerial insecticide spraying on West Nile virus disease--north-central Texas, 2012.

During 2012, four north-central Texas counties experienced high West Nile virus (WNV) disease incidence. Aerial insecticide spraying was conducted in two counties. To evaluate the effect of spraying on WNV disease, we calculated incidence rate ratios (IRRs) in treated and untreated areas by comparing incidence before and after spraying; for unsprayed areas, before and after periods were defined by using dates from a corresponding sprayed area.

How we didn't clean up until we washed our hands: shigellosis in an elementary and middle school in North Texas.

Background: Shigella outbreaks often continue for months and are linked frequently to poor hygiene and hand washing. Such outbreaks are found often in day care facilities, but rarely are reported in schools. We present the investigation of an outbreak in autumn 2007 at a building that housed an elementary school and a middle school in separate wings in a small Texas city north of Dallas-Fort Worth.

Physician assistants and bioterrorism preparedness.

Despite the resources dedicated since 2001 to training health providers in emergency and bioterrorism preparedness and response, the literature on the participation of physician assistants (PAs) is very limited. The purpose of this pilot study was to explore the training level and experiences of PAs in the diagnosis and treatment of chemical, biological, radiological, nuclear, and explosive agents that could be used in a bioterrorism attack. The study population consisted of licensed PAs in 37 northern Texas counties.

Assessing the readiness and training needs of non-urban physicians in public health emergency and response.

Emergency readiness has become a public health priority for United States communities after the 9/11 attacks. Communities that have a less developed public health infrastructure are challenged to organize preparedness and response efforts and to ensure that health care providers are capable of caring for victims of terrorist acts. A survey was used to assess non-urban physicians' prior experience with and self-confidence in treating, and preferred training needs for responding to chemical, biologic, radiologic, nuclear, and explosive (CBRNE) cases.
