Multistate surveillance for laboratory-confirmed, influenza-associated hospitalizations in children: 2003-2004.

BACKGROUND: Increasing use of rapid influenza diagnostics facilitates laboratory confirmation of influenza infections. We describe laboratory-confirmed, influenza-associated hospitalizations in a population representing almost 6% of children in the United States. METHODS: We conducted population-based surveillance for influenza-associated hospitalizations between October 1, 2003, and March 31, 2004, in 54 counties in 9 states (4.2 million children) participating in the Emerging Infections Program Network. Clinical characteristics, predictors of intensive care unit admission and geographic and age-specific incidence were evaluated. RESULTS: Surveillance identified 1,308 case-patients; 80% were <5 years and 27% were <6 months of age. Half of the patients and 4 of 5 pediatric deaths did not have a medical indication for influenza vaccination and were outside the 6- to 23-month age group. Twenty-eight percent of case-patients had radiographic evidence of a pulmonary infiltrate, 11% were admitted to intensive care and 3% received mechanical ventilation. The median length of hospital stay was 2 days. Community-acquired invasive bacterial coinfections (1% of patients) were associated with intensive care admission (adjusted odds ratio, 16.9; 95% confidence interval, 5.0-56.8). Thirty-five percent of patients >or=6 months old had received at least one influenza vaccine dose that season. The overall incidence of influenza-associated hospitalizations was 36 per 100,000 children (range per state, 10 per 100,000 to 86 per 100,000). CONCLUSIONS: Influenza was an important cause of hospitalizations in children during 2003-2004. Hospitalizations were particularly common among children <6 months of age, a group for whom influenza vaccine is not licensed. Continued surveillance for laboratory-confirmed influenza could inform prevention strategies.

Knowledge, attitude, and practice of the use of irradiated meat among respondents to the FoodNet Population Survey in Connecticut and New York.

Irradiation of fresh meat to control microbial pathogens received approval from the federal government in February 2000. Food irradiation is a useful, albeit underutilized, process that can help protect the public from foodborne illnesses. The objective of this study was to determine consumer knowledge, attitudes, and practices toward irradiated meat products. Data were obtained from a single-stage random-digit dialing telephone survey of residents of the Foodborne Diseases Active Surveillance Network (FoodNet) sites conducted in 2002 to 2003, which included supplemental questions about food safety and irradiated meat for residents of the Connecticut and New York sites. Thirty-seven percent of 3,104 respondents knew that irradiated fresh meat was available for purchase; however, only 2% found the product where they shopped. Knowledge of product availability was significantly influenced by whether a respondent lived in a county with one or more grocery stores operated by chain A, which had actively promoted the sale of irradiated fresh ground beef during the survey period. In a logistic regression model, after adjusting for other factors, respondents living in a county with chain A were more likely to know that irradiated products could be purchased than respondents living in other counties (odds ratio 2.0; 95% confidence interval 1.5 to 2.5). This finding suggests that public education efforts by an individual grocery store chain can have an important effect on knowledge of irradiated food.

Four laboratory-associated cases of infection with Escherichia coli O157:H7.

An investigation of four cases of infection with Escherichia coli O157:H7 among laboratorians from different clinical laboratories revealed that the DNA fingerprint pattern of each case isolate was indistinguishable from that of an isolate handled in the laboratory prior to illness. These data suggest that the infections were laboratory acquired, and they demonstrate the importance of laboratorians strictly adhering to biosafety practices recommended for the handling of infectious materials.

Dramatic decrease in the incidence of Salmonella serotype Enteritidis infections in 5 FoodNet sites: 1996-1999.

Salmonella serotype Enteritidis (SE) emerged as the most common Salmonella serotype among infected persons in the United States during the 1980s and 1990s, with infections reaching a peak in 1995. During the past decade, farm-to-table control measures have been instituted in the United States, particularly in regions with the highest incidence of SE infection. We report trends in the incidence of SE in the 5 original surveillance areas of the Foodborne Diseases Active Surveillance Network during 1996-1999: Minnesota, Oregon, and selected counties in California, Connecticut, and Georgia. Overall, the incidence of SE decreased 46% from 1996 to 1999. The greatest decrease was in Connecticut (71%), followed by northern California (50%), Minnesota (46%), and Oregon (13%). Although SE infection remains an important public health concern, there has been a remarkable decrease in its incidence. This decrease may be a result of targeted interventions, including on-farm control measures, refrigeration, and education efforts.
