Surveillance is the foundation of public health practice. This review examines the experience of surveillance in the Expanded Programme on Immunization (EPI). Surveillance systems include routine reporting, sentinel surveillance, and community-based reporting. ⋯ The surveillance of vaccine-preventable diseases has evolved as programmes mature, to monitor progress towards disease control targets. The establishment of goals to reduce measles cases by 90%, eliminate neonatal tetanus, and eradicate poliomyelitis has put increased emphasis on the need for effective disease surveillance. This opportunity should be taken to promote strengthening of national routine systems for disease surveillance, to make them effective instruments for prevention and control of diseases of public health importance.

ReviewDrug injecting and HIV infection among the population of drug abusers in Asia.
Opium has been produced and consumed since the nineteenth century in the areas of Asia currently referred to as the Golden Crescent and the Golden Triangle. In the 1970s and 1980s, most countries from Afghanistan to Japan experienced a heroin epidemic of varying degrees of severity. Opium and heroin abuse appeared to be more severe in countries and areas where those drugs were produced, an exception being Hong Kong, which has had a large population of heroin abusers for more than two decades. ⋯ Great caution should be exercised in interpreting prevalence because of vast differences in methods of assessment. Given the vulnerability of intravenous drug abusers to rapid transmission of HIV infection, the prevention of drug injecting is of paramount importance in arresting the spread of the epidemic. Efforts to contain drug abuse, though difficult, are a principal means of achieving that end.

As measles continues to exact a high toll on infant mortality, particularly in developing countries, optimal strategies for the control of the disease are under discussion. As part of this debate, the place of 2-dose measles immunization schedules is reviewed regarding their potential as a strategy to improve measles control. To date, WHO has not recommended the use of a 2-dose schedule. ⋯ Long-term safety should be determined through studies of adequate size. Programmes already using 2-dose schedules are encouraged to evaluate their impact on disease incidence, cost, vaccine usage, and effect on coverage. Until further evaluation is complete, a high and timely coverage with one dose of measles vaccine in all areas remains the first priority for all immunization programmes.

Two hundred and fourteen young women received acquired immunodeficiency syndrome (AIDS) prevention interventions at an inner-city family health center serving minority patients predominantly. The community in which the health center is located has a high incidence of intravenous (IV) drug abuse. Either a peer or a health care provider delivered the intervention. ⋯ In addition, subjects in both groups who were sexually active stated immediately after the intervention that asking a sexual partner about past sexual experience would now be less difficult, and at one-month follow-up they reported a significant decrease in the frequency of vaginal sex. Our findings suggest that counseling by physicians can achieve more changes in knowledge of sexual risks, whereas peer education can achieve greater changes in knowledge about IV drug use. Results show that both approaches to AIDS prevention used in this study can significantly affect knowledge, attitudes, and sexual behavior.
