Features of illnesses caused by five species of Campylobacter, Foodborne Diseases Active Surveillance Network (FoodNet) - 2010-2015.

The Foodborne Diseases Active Surveillance Network (FoodNet) conducts population-based surveillance for Campylobacter infection. For 2010 through 2015, we compared patients with Campylobacter jejuni with patients with infections caused by other Campylobacter species. Campylobacter coli patients were more often >40 years of age (OR = 1·4), Asian (OR = 2·3), or Black (OR = 1·7), and more likely to live in an urban area (OR = 1·2), report international travel (OR = 1·5), and have infection in autumn or winter (OR = 1·2). Campylobacter upsaliensis patients were more likely female (OR = 1·6), Hispanic (OR = 1·6), have a blood isolate (OR = 2·8), and have an infection in autumn or winter (OR = 1·7). Campylobacter lari patients were more likely to be >40 years of age (OR = 2·9) and have an infection in autumn or winter (OR = 1·7). Campylobacter fetus patients were more likely male (OR = 3·1), hospitalized (OR = 3·5), and have a blood isolate (OR = 44·1). International travel was associated with antimicrobial-resistant C. jejuni (OR = 12·5) and C. coli (OR = 12) infections. Species-level data are useful in understanding epidemiology, sources, and resistance of infections.

Typhoid fever acquired in the United States, 1999-2010: epidemiology, microbiology, and use of a space-time scan statistic for outbreak detection.

Although rare, typhoid fever cases acquired in the United States continue to be reported. Detection and investigation of outbreaks in these domestically acquired cases offer opportunities to identify chronic carriers. We searched surveillance and laboratory databases for domestically acquired typhoid fever cases, used a space-time scan statistic to identify clusters, and classified clusters as outbreaks or non-outbreaks. From 1999 to 2010, domestically acquired cases accounted for 18% of 3373 reported typhoid fever cases; their isolates were less often multidrug-resistant (2% vs. 15%) compared to isolates from travel-associated cases. We identified 28 outbreaks and two possible outbreaks within 45 space-time clusters of ⩾2 domestically acquired cases, including three outbreaks involving ⩾2 molecular subtypes. The approach detected seven of the ten outbreaks published in the literature or reported to CDC. Although this approach did not definitively identify any previously unrecognized outbreaks, it showed the potential to detect outbreaks of typhoid fever that may escape detection by routine analysis of surveillance data. Sixteen outbreaks had been linked to a carrier. Every case of typhoid fever acquired in a non-endemic country warrants thorough investigation. Space-time scan statistics, together with shoe-leather epidemiology and molecular subtyping, may improve outbreak detection.

Addressing women concerns. Philippines. The Hague Forum.

PIP: Since the 1994 International Conference on Population and Development (ICPD), the Philippine government has worked closely with nongovernmental and peoples' organizations to push reforms which promote development which is broad-based, sustainable, and focused upon human resources. These initiatives recognized the important role of population and human development, and try to achieve rapid economic growth while protecting the environment. The government worked closely with civil society to draft a medium-term development plan for 1993-98 to improve the quality of life for all Filipinos. Reproductive health will be an important component of the Medium-Term Philippine Development Plan for 1999-2004. However, the necessary resources must be mobilized to carry out all elements of the program of action. Since the ICPD, total funding for reproductive health and family planning reached Philippine P 1 billion, of which 58% was provided by the foreign donor community. So far, the Philippine government has been blocked by the Catholic Church from allocating more public funds for contraception. Local government units need to take a more direct and active role in implementing rural health programs in general and reproductive health programs in particular.^ieng

Malnutrition and acute respiratory tract infections in Filipino children.

The impact of malnutrition on morbidity and mortality associated with acute respiratory tract infection (ARI) was studied in Filipino children less than 5 years old. Malnutrition measured by weight-for-age Z-scores of less than -3 SD and less than -2 SD from the National Center for Health Statistics median reference population was associated with the following significant relative risks of morbidity: 1.24 (95% confidence interval [CI] = 1.14, 1.34) and 1.14 (95% CI = 1.08, 1.19), respectively, for ARI; and 1.9 (95% CI = 1.46, 2.39) and 1.2 (95% CI = 1.03, 1.47), respectively, for acute lower respiratory tract infection (ALRI). These risk ratios remained significant when adjusted for age, crowding, and parental smoking. Malnourished children with severe ALRI also had a mortality risk two to three times higher than that of healthy children. This risk remained significant even when adjusted for significant predictors of mortality, including clinical complications, concurrent measles, severe infections, and female gender; and for clinical factors, including extent of pneumonic infiltrates, dehydration, and hepatic enlargement. These findings underscore the importance of nutritional intervention in the control of morbidity and mortality among patients with ARI.

Patterns of acute respiratory tract infection in children: a longitudinal study in a depressed community in Metro Manila.

The incidences of acute respiratory tract infection (ARI) and acute lower respiratory infection (ALRI) were 6.1 and 0.5 per child-year, respectively, in children less than 5 years old in a depressed urban community in Manila. The peak age-specific incidence occurred in those children 6-23 months old for ARI and 6-11 months old for ALRI. Age less than 2 years, malnutrition, household crowding, and parental smoking were associated with a statistically significant, though modest, increase in ARI morbidity. The crude mortality rate was 14.3 per 1,000 children 0-4 years old, with a corresponding ARI-specific mortality rate of 8.9 per 1,000. The prevalence of viral infection was 32.8 and that of bacteremic ALRI was 6.7 per 1,000 children with moderate ALRI. Respiratory syncytial virus was the predominant viral pathogen, while Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus were the most frequently isolated bacterial pathogens. Transmission of respiratory pathogens in depressed communities, facilitated by inadequate housing, inaccessible health services, and prevalent malnutrition, will continue unless meaningful socioeconomic improvement is realized.

Child care practices of mothers: implications for intervention in acute respiratory infections.

An epidemiological study of acute respiratory infection (ARI) in an urban community showed poor utilization of available health services. This prompted us to undertake this study to identify determinants of child care practices of mothers through a focus group discussion and survey of the knowledge, attitudes and practices of mothers. The results will form the basis of appropriate health education strategy geared towards control of ARI. They showed that, generally, the mothers were unable to recognize a severe infection. Poor diagnostic ability compounded by a limited knowledge of the appropriate management of varying types or degrees of ARI resulted in inappropriate action. Consequently, there was a high rate of self-medication and a low rate of health service utilization. In addition, there was low compliance with childhood immunizations. With these limitations in the mother's knowledge and practices, an education programme utilizing an informative print material was devised to upgrade the mother's ability to recognize signs of ARI and to improve her management of the condition.
