Abstract

Novel indices were developed representing estimated stages in the mosquito life cycle and its ecology, and informed with meteorological data. We used descriptive statistics to identify relationships between meteorological/ecological trends and peak infection rates (IRs), and mixed model linear regression to identify meteorological/ecological trends that were significantly associated with increases in mosquito IRs.

 

Results showed increased mean weekly temperature as a significant driver of increased IRs between 2002 and 2006 during oviposition (the trapping week); the gonotrophic cycle; the egg, larvae, and pupae stage; the development of oviposition sites; and during the over-winter months preceding trapping. Decreases in weekly cumulative precipitation during the last half of the development of oviposition sites, and the egg, larvae, and pupae stage, were significantly associated with increases in IRs. Increased cumulative precipitation during the first half of the development of oviposition sites was significantly associated with increases in IRs. Decreases in the weekly Palmer Drought Index during the development of oviposition sites were significantly associated with increases in IRs.

Abstract

Cosmetologists face a variety of occupational health and safety challenges. To gather information on respiratory issues related to work as a cosmetologist, licensed cosmetologists were invited by e-mail to participate in a short online survey. The survey collected demographic data, work history, respiratory symptoms, product usage, and health and safety training. Results revealed that while 57% of cosmetologists reported having received training on customer or consumer safety, only 10.5% had received training on worker health such as work-related asthma and/or breathing issues. Respiratory symptoms were reported by 46% of respondents. Length of employment and the use of glues or adhesives were associated with a diagnosis of asthma.

For centuries, people have recognized that rats and mice are not only a nuisance but are a public health problem. NACCHO conducted a comprehensive assessment to solicit information about the nation's local health departments' vector and rodent control program capacities. From this session, attendees will be able to identify the capacities, needs, and existing and future challenges of rodent control programs in public health departments.

Elevated nitrogen concentrations in groundwater and surface waters are a health and environmental concern. The presenters monitored concentrations of nitrogen in groundwater at sites that use onsite wastewater systems (OWS), in surface waters, and in deeper groundwater near the systems to determine the OWS nitrogen contributions. They’ll describe the monitoring techniques and results to provide attendees with a holistic understanding of the role of the OWS in the nitrogen cycle and possible approaches to watershed nutrient management plans.

Abstract

Outbreaks of foodborne illness caused by Clostridium perfringens are not usually the result of intoxication and testing of suspected menu items for colony count can often identify the causative item. We describe a large outbreak at a county correctional facility in which the data suggest that illness by intoxication contributed substantially to the outbreak: 29 out of 108 surveyed cases (26.9%) developed symptoms within 2.5 hr of when meal service began. Inmate testimony further suggests advanced food decay. Bacterial analyses of food samples indicated a smaller population of C. perfringens in the chicken taco meat mixture (<10 CFU/g, enterotoxin positive) compared with other items. Statistical analyses of food history data provided substantially more support for the chicken taco meat mixture as causative (odds ratio = 55.79, 95% confidence interval [19.72, 157.83], p < .001) than other menu items. Environmental investigation and testimony from inmates provided additional support implicating the chicken taco meat mixture.

Article Abstract

During the summer of 2005 an outbreak of norovirus acute gastroenteritis occurred in a residential college summer camp and was reported to the local health department. The outbreak spread rapidly to several other groups concurrently sharing the same facilities. During the investigation, fomites were sampled at different times in dorm rooms and tested for norovirus. The number of norovirus-positive rooms increased after the first room cleaning, from 40% to 73%. After the initial cleaning, the staff was instructed on proper cleaning and disinfection procedures and provided with disposable disinfecting wipes to reduce cross contamination, and the number of norovirus-positive rooms decreased to 30%. These findings reinforce the need for appropriate cleaning and disinfection procedures during a norovirus outbreak.
