A statewide survey of immunization rates in Minnesota school age children: implications for targeted assessment and prevention strategies.

Background: A retrospective statewide immunization survey of the 69115 Minnesota children who entered kindergarten in 1992 was conducted.

Methods: Information was collected from school immunization records on date of birth, dates of vaccination for each dose of vaccine, address of residence and race/ethnicity (when available). Immunization rates were assessed retrospectively for each month of a child's life from 2 to 48 months of age.

A multistate outbreak of Salmonella javiana and Salmonella oranienburg infections due to consumption of contaminated cheese.

Objective: To determine the source of an outbreak of Salmonella javiana and Salmonella oranienburg infections.

Design: Laboratory-based statewide surveillance for Salmonella infections and two separate case-control studies.

Setting: Community- and industry-based studies conducted from May through October 1989.

An outbreak of Salmonella enteritidis infection at a fast-food restaurant: implications for foodhandler-associated transmission.

An outbreak of Salmonella enteritidis infection occurred in patrons and employees of a fast-food restaurant. Transmission took place over a 9-day period. A single employee (employee A) was identified who had onset of gastrointestinal illness 1 day before the first reported patron exposures and had S.

An outbreak of Escherichia coli O157:H7 colitis associated with consumption of precooked meat patties.

An outbreak of Escherichia coli O157:H7 hemorrhagic colitis at a Minnesota junior high school in October 1988 comprised 32 cases among 1562 students (attack rate, 2.0%). Four children were hospitalized; none developed hemolytic-uremic syndrome.

An outbreak of psittacosis in Minnesota turkey industry workers: implications for modes of transmission and control.

From June through November 1986, an outbreak of psittacosis occurred in turkey industry workers in central Minnesota. A total of 186 suspect cases were identified, and 122 cases (66%) were serologically confirmed. Cases occurred in three turkey processing plants, two rendering plants, one farm, and one "further processing" plant (where meat is removed from previously eviscerated carcasses and consumer products, such as roasts, are made).

A foodborne outbreak of Norwalk virus gastroenteritis. Evidence for post-recovery transmission.

From November 10-16, 1982, 220 (57%) of 383 attendees at eight banquets for which food had been prepared at a single hotel restaurant and the employees of the hotel had onset of Norwalk virus gastroenteritis. Epidemiologic investigation of the three largest banquets confirmed consumption of potato and fruit salads (banquet A), coleslaw (banquet B), and tossed salad (banquet C) to be significantly associated with illness. Between November 8-19, similar illness occurred in seven (54%) of 13 hotel kitchen employees.

A point-source outbreak of campylobacteriosis associated with consumption of raw milk.

After a one-day field trip to a Minnesota farm, 22 (45%) of 49 third-grade students and three (14%) of 21 adult chaperones developed campylobacteriosis. Campylobacter jejuni was isolated from specimens of 13 children and one asymptomatic adult. Illness was associated with the consumption of raw milk during a picnic lunch (odds ratio = 41.

Norwalk gastroenteritis: a community outbreak associated with bakery product consumption.

From 23 to 26 August 1982, a gastrointestinal illness occurred among 129 of 248 (52%) persons interviewed who had attended four social events in the Minneapolis-St. Paul area. The median incubation period was 36 hours, and symptoms included diarrhea, nausea, headache, and vomiting.
