A cluster of injuries at a water slide in Washington State.

Interviews were conducted with 46 people injured on a newly opened water slide in Washington State during the summer of 1983, and 46 age-matched controls. The injuries included nine concussions and eight spinal fractures. The odds ratio associated with being 10 per cent over ideal body weight, adjusted for age and sex, was 1.6 (95% C.I. 1.1-2.5). Three of eight people with spinal fractures were riding with another person between their legs, compared with two of 38 other injured riders (OR = 10.8, 95% C.I. 1.8-63.5).

Simple bead injection-flow injection system for the determination of copper.

We demonstrate the extended application of a simple bead injection-flow injection system with a modified simple colorimetric detection unit for the determination of low amount of Cu2+ in samples of different matrices (water and supplement tablet samples) with minimal sample pretreatment by employing ammonium pyrrolidinedithiocarbamate (APDC) reagent.

Outbreak of travel-related pontiac fever among hotel guests illustrating the need for better diagnostic tests.

BACKGROUND: Pontiac fever (PF), a legionellosis with influenza-like symptoms and high attack rates, is rarely reported. Travel-related outbreaks can elude detection because infected persons are often widely removed geographically from the transmission source before illness onset. Thirty-one persons staying at an Illinois hotel during August 9 to 11, 2002, reported influenza-like symptoms to local health departments within 24 to 48 hours of checkout. We investigated to identify the cause and source of illness to guide control measures. METHODS: Hotel water samples were collected for culture. A telephone questionnaire detailing illness symptoms and exposures was administered to all who were guests at the hotel from August 9 to 15 (n = 380). A case was defined as onset of fever, headache, and myalgia in a guest in the 14 days following the hotel stay. Patient sera were tested by hemagglutination assay for antibodies to Legionella species. RESULTS: Among 204 questionnaire respondents from 15 states and Canada, 50 met the case definition. Among persons exposed to the swimming pool/whirlpool spa area, 63% (47 of 75) became ill versus 3% (3 of 110) of unexposed persons (relative risk 23.0, 95% CI 7.4-71.1). Illness risk increased with increasing time exposed to the pool/spa. Approximately 95 to 115 bathers per day, two to three times above the usual number, used the spa during August 9 to 11. Three Legionella species, L. dumoffii, L. maceachernii, and L. micdadei, were isolated from spa filter backwash cultures. Two of 15 ill persons with acute- and convalescent-phase sera had a greater than fourfold rise in antibody titer to L. micdadei. CONCLUSIONS: PF was associated with exposure to a hotel pool/spa area. Heavy bather usage likely contributed to a decreased effectiveness of the disinfectant in the whirlpool spa, possibly promoting bacterial aerosolization. Linking case information from many states is essential in identifying and eliminating the source of disease transmission in travel-related outbreaks of PF. Clinicians should be aware of PF in the differential diagnosis of patients with influenza-like symptoms following recent travel, particularly with exposure to a communal-use whirlpool spa.

Nested polymerase chain reaction for amplification of the Cryptosporidium oocyst wall protein gene.

We developed a sensitive nested polymerase chain reaction procedure for the Cryptosporidium oocyst wall protein (COWP) gene. Amplification and genotyping were successful in 95.2% of 1,680 fecal samples, 77.6% by the unnested and 17.6% by the nested COWP procedure. The COWP gene was amplified from 2,128 fecal samples: 71 from livestock animals and 2,057 from humans. This series included 706 cases from seven drinking water-associated outbreaks and 51 cases from five swimming pool-associated outbreaks, as well as 1,300 sporadic cases.

An outbreak of cryptosporidiosis associated with an animal nursery at a regional fair.

Cryptosporidiosis is a common gastrointestinal illness that is transmitted from infected persons, animals, or contaminated water or food. This article reports on an outbreak of cryptosporidiosis associated with an animal nursery at an agricultural show held in northern Tasmania during October 2001. Eighty-one per cent of cases (38/47) notified to the Tasmanian Department of Health and Human Services over a 35 day period were interviewed to determine potential sources of infection. Eighty-one per cent of interviewed cases (29/36) reported that they had attended the agricultural show, and 75 per cent (27/36) reported contact with animals in the animal nursery. Cases occurring more than one incubation period after the agricultural show were significantly more likely to have had contact with someone else with diarrhoea (p<0.01). This is the first reported outbreak of cryptosporidiosis associated with an animal nursery in Australia. The outbreak demonstrates the importance of infection control policies and hygiene measures in the animal nursery setting.

Drowning: community aspects.

One hundred and ninety-six fatal immersion accidents occurred in Geelong and district during the 20-year period, 1959 to 1978. Of 54 drownings in children aged 16 years and younger, 43 (80%) occurred in males and 33 (61%) in fresh water. All 14 drownings in children under four years of age occurred in fresh-water sites, 12 of which were about the home. Immediate and optimal resuscitative measures in such children are extremely important.

Swimming ability of children: a survey of 4000 Queensland children in a high drowning region.

The swimming ability of 4128 Queensland school children was studied. The median age for swimming 10 metres is 6.5 years. Ninety-five percent of children are able to swim by 11 years of age. Cumulative frequency curves, by age, are presented for the ability to swim 10 and 50 metres: the latter distance is of relevance in boating accidents. Twenty percent fewer children from lower socioeconomic levels are able to swim. Water safety training is as important as swimming lessons.
