Am J Trop Med Hyg 2014 91 (2) 240-5 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. In treated areas, WNV neuroinvasive disease incidence before and after spraying was 7.31/100,000 persons and 0.28/100,000 persons, respectively; the IRR was 26.42 (95% confidence interval [CI]: 12.42-56.20). In untreated areas, the before and after incidence was 4.80/100,000 persons and 0.45/100,000 persons, respectively; the IRR was 10.57 (95% CI: 6.11-18.28). The ratio of IRRs was 2.50 (95% CI: 0.98-6.35). Disease incidence decreased in both areas, but the relative change was greater in aerial-sprayed areas. |
How we didn't clean up until we washed our hands: shigellosis in an elementary and middle school in north Texas

South Med J 2012 105 (1) 1-4 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. METHODS: We canvassed local hospitals, school attendance records, and physician offices for cases. Ill individuals were interviewed using a standard questionnaire for symptoms, disease onset, and the presence of the illness in an ill person's household. RESULTS: A music teacher was the index case for this outbreak of gastrointestinal illness caused by S. sonnei. Ten percent of the students in the school building were ill, and 15 households had secondary cases. Installing liquid soap in dispensers in student restrooms was the initial control measure, followed by sustained instruction in hand washing, scheduled hand washing times, and monitored cleaning and disinfection procedures for surfaces and inanimate objects. Enhanced surveillance detected no new cases in the school district. CONCLUSIONS: Appropriate soap supplies and repeated instruction in hand washing and its monitoring were needed to control the outbreak. |
