What is the Health Impact of Day Care Attendance on Infants and Preschoolers?

The impact of various child care arrangements on the health of infants and preschool children is not known in any systematic way, yet by 1990 more than 10 million of these children may be receiving their care in day care facilities (1). Concerns over the health of these children and health practices within day care facilities have already led some States to place regulation of day care facilities under the jurisdiction of the department of health (2,3), and others are presently considering such legislation. In addition, the American Academy of Pediatrics has recently published Health in Day Care, a manual for health professionals who are being increasingly called upon for advice concerning health issues related to children in day care facilities (4)

Business and public health collaboration for emergency preparedness in Georgia: a case study

BACKGROUND: Governments may be overwhelmed by a large-scale public health emergency, such as a massive bioterrorist attack or natural disaster, requiring collaboration with businesses and other community partners to respond effectively. In Georgia, public health officials and members of the Business Executives for National Security have successfully collaborated to develop and test procedures for dispensing medications from the Strategic National Stockpile. Lessons learned from this collaboration should be useful to other public health and business leaders interested in developing similar partnerships. METHODS: The authors conducted a case study based on interviews with 26 government, business, and academic participants in this collaboration. RESULTS: The partnership is based on shared objectives to protect public health and assure community cohesion in the wake of a large-scale disaster, on the recognition that acting alone neither public health agencies nor businesses are likely to manage such a response successfully, and on the realization that business and community continuity are intertwined. The partnership has required participants to acknowledge and address multiple challenges, including differences in business and government cultures and operational constraints, such as concerns about the confidentiality of shared information, liability, and the limits of volunteerism. The partnership has been facilitated by a business model based on defining shared objectives, identifying mutual needs and vulnerabilities, developing carefully-defined projects, and evaluating proposed project methods through exercise testing. Through collaborative engagement in progressively more complex projects, increasing trust and understanding have enabled the partners to make significant progress in addressing these challenges. CONCLUSION: As a result of this partnership, essential relationships have been established, substantial private resources and capabilities have been engaged in government preparedness programs, and a model for collaborative, emergency mass dispensing of pharmaceuticals has been developed, tested, and slated for expansion. The lessons learned from this collaboration in Georgia should be considered by other government and business leaders seeking to develop similar partnerships

Syndromic Surveillance and Bioterrorism-related Epidemics

To facilitate rapid detection of a future bioterrorist attack, an increasing number of public health departments are investing in new surveillance systems that target the early manifestations of bioterrorism-related disease. Whether this approach is likely to detect an epidemic sooner than reporting by alert clinicians remains unknown. The detection of a bioterrorism-related epidemic will depend on population characteristics, availability and use of health services, the nature of an attack, epidemiologic features of individual diseases, surveillance methods, and the capacity of health departments to respond to alerts. Predicting how these factors will combine in a bioterrorism attack may be impossible. Nevertheless, understanding their likely effect on epidemic detection should help define the usefulness of syndromic surveillance and identify approaches to increasing the likelihood that clinicians recognize and report an epidemic

Preexisting Japanese Encephalitis Virus Neutralizing Antibodies and Increased Symptomatic Dengue Illness in a School-Based Cohort in Thailand

Dengue viruses (DENVs) and Japanese encephalitis virus (JEV) have significant cross-reactivity in serological assays, but the possible clinical implications of this remain poorly understood. Interactions between these flaviviruses are potentially important for public health because wild-type JEV continues to co-circulate with DENV in Southeast Asia, the area with the highest burden of DENV illness, and JEV vaccination coverage in this region is high. In this study, we examined how preexisting JEV neutralizing antibodies (NAbs) influenced the clinical severity of subsequent DENV infection using data from a prospective school-based cohort study in Thailand that captured a wide range of clinical severities, including asymptomatic, non-hospitalized, and hospitalized DENV infections. We found that the prior existence of JEV NAbs was associated with an increased occurrence of symptomatic versus asymptomatic DENV infection. This association was most notable in DENV-naives, in whom the presence of JEV NAbs was also associated with an illness of longer duration. These findings suggest that the issue of heterologous flavivirus immunity and DENV infection merits renewed attention and interest and that DENV vaccine developers might incorporate detailed assessments of preexisting immunity to non-DENV flaviviruses and histories of vaccination against non-DENV flaviviruses in evaluating DENV vaccine safety and efficacy
