The use of vaccines has been instrumental in reducing the incidence and severity of many different diseases. The Healthy People 2000 program lists improving immunization rates as one of its top goals. However, the national immunization rate falls far below the national goal. As health care providers, it is important to understand the age-specific immunization recommendations and contraindications.

OBJECTIVE: To assess the costs and health effects of a range of interventions for preventing the spread of HIV and for treating people with HIV/AIDS in the context of the millennium development goal for combating HIV/AIDS. DESIGN: Cost effectiveness analysis based on an epidemiological model. SETTING: Analyses undertaken for two regions classified using the WHO epidemiological grouping-Afr-E, countries in sub-Saharan Africa with very high adult and high child mortality, and Sear-D, countries in South East Asia with high adult and high child mortality. DATA SOURCES: Biological and behavioural parameters from clinical and observational studies and population based surveys. Intervention effects and resource inputs based on published reports, expert opinion, and the WHO-CHOICE database. MAIN OUTCOME MEASURES: Costs per disability adjusted life year (DALY) averted in 2000 international dollars (Int dollars). RESULTS: In both regions interventions focused on mass media, education and treatment of sexually transmitted infections for female sex workers, and treatment of sexually transmitted infections in the general population cost < Int150 dollars per DALY averted. Voluntary counselling and testing costs < Int350 dollars per DALY averted in both regions, while prevention of mother to child transmission costs < Int50 dollars per DALY averted in Afr-E but around Int850 dollars per DALY in Sear-D. School based education strategies and various antiretroviral treatment strategies cost between Int500 dollars and Int5000 dollars per DALY averted. CONCLUSIONS: Reducing HIV transmission could be done most efficiently through mass media campaigns, interventions for sex workers and treatment of sexually transmitted infections where resources are most scarce. However, prevention of mother to child transmission, voluntary counselling and testing, and school based education would yield further health gains at higher budget levels and would be regarded as cost effective or highly cost effective based on standard international benchmarks. Antiretroviral therapy is at least as cost effective in improving population health as some of these interventions.
OBJECTIVE: To determine the costs and effectiveness of selected child health interventions-namely, case management of pneumonia, oral rehydration therapy, supplementation or fortification of staple foods with vitamin A or zinc, provision of supplementary food with counselling on nutrition, and immunisation against measles. DESIGN: Cost effectiveness analysis. DATA SOURCES: Efficacy data came from published systematic reviews and before and after evaluations of programmes. For resource inputs, quantities came from literature and expert opinion, and prices from the World Health Organization Choosing Interventions that are Cost Effective (WHO-CHOICE) database, RESULTS: Cost effectiveness ratios clustered in three groups, with fortification with zinc or vitamin A as the most cost effective intervention, and provision of supplementary food and counselling on nutrition as the least cost effective. Between these were oral rehydration therapy, case management of pneumonia, vitamin A or zinc supplementation, and measles immunisation. CONCLUSIONS: On the grounds of cost effectiveness, micronutrients and measles immunisation should be provided routinely to all children, in addition to oral rehydration therapy and case management of pneumonia for those who are sick. The challenge of malnutrition is not well addressed by existing interventions.

Both health and education are linked to economic performance. The success of education depends on good health, and vice versa. Modern education should help young people to determine values, and accept responsibility for their health and social behaviour. The success of health promotion in schools requires the joint efforts of both the health and education sectors. A comprehensive programme is needed to include teachers' training, curriculum development, community participation, changing policies and practices, and research. All these components are needed to build up a successful model of a health promoting school. The "Healthy Schools Programme" in Hong Kong gives a good example of close partnership between the health and education sectors, and moves towards a multidisciplinary approach and active learning towards health promotion.
The stated mission of current public health activities is to prevent mortality, morbidity, and disability. Though this mission is a noble challenge, attention is now being drawn to that group of the public who are not prevented from living with a disability. This chapter seeks to redefine the functions of public health in the field of disability. It describes the changing demographics of disability and provides a framework for addressing the complex issues associated with defining disability. Finally, we outline a strategy for stronger and clearer public health presence to improve the health and well-being of people with disabilities.

The decade of the '90s witnessed the emergence of health promotion as a national priority for all age groups. Despite the fact that Healthy People 2010 identified objectives for the nursing home population, little is known about factors that promote the practice of health-promoting behaviors by nursing home residents. This study examined the separate and combined contributions of personal and contextual influences on the practice of health-promoting behaviors by nursing home residents. One hundred eighty-four residents and 90 staff members from six nursing homes participated in this study. Using a modified version of contextual regression analysis, 57.8% of the variance in health-promoting lifestyle (HPL) behaviors was explained when all variables were entered into the equation. Personal influences explained a significant amount of variation (53.5%) in current HPL behaviors. These findings underscore the importance of looking at ways to support the efforts of nursing home residents to engage in the practice of health-promoting behaviors.
