SCIENTIFIC AMERICAN. 1976 Oct; 235(4):25-33.The key events in the eradication of smallpox worldwide are related. Smallpox virus was spread by droplets, only from the appearance of the rash until scabs form, 4 weeks later. It only infected humans, making it a potential disease for eradication. It had been endemic in populous areas, largely China and India in ancient times, appearing in Europe in the 6th century and in America in 1520. Smallpox vaccination was known as variolation before the modern practice of vaccination with cowpox (Vaccinia) was demonstrated in 1796. Success of the 10 year long world eradication campaign depended on production of heat-stable vaccines and a reusable pronged needle that used little material. The U.S.S.R. suggested the campaign in 1959, but the current campaign began in 1976. The 1st strategy was intensive vaccination, with moderate success. Subsequent strategies involved surveillance and containment, along with improved reporting methods. The concept of an infected village was introduced, and house to house searches were instituted. Victims were put under guard and all villagers were vaccinated. The last case of virulent smallpox occurred in Bangladesh in October 1975, and of mild smallpox in Ethiopia in August 1976. The cost of the entire 10-year global eradication was $83 million for foreign assistance, and about $160 million spent by the individual countries. This is small compared to an estimated $2 billion yearly spent to control smallpox. It is ironic that smallpox became an epidemic pestilence upon the growth of populations, yet it played a major role in preventing population growth until variolation and vaccination became common.
Washington, D.C., U.S. Office of International Health, Division of Planning and Evaluation, 1976. 144 p. (Syncrisis: the dynamics of health, XIX)This report uses available statistics to examine health conditions in Senegal and their interaction with socioeconomic development. Background data are presented, after which population, health status, nutrition, environmental health, health infrastructure, facilities, services and manpower, national health policy and planning, international organizations, and the Sahel are discussed. Diseases such as malaria, measles, tuberculosis, trachoma and venereal diseases are endemic in Senegal, and high levels of infant and childhood mortality exist throughout the country but especially in rural areas. Diarrhea, respiratory infections, and neonatal tetanus contribute to this mortality and are evidence of the poor health environment, and lack of basic services including nutrition assistance, health education, and potable water. Nutrition in Senegal appears to be good in general, but seasonal and local variations sometimes produce malnutrition. Lowered fertility rates would reduce infant and maternal mortality and morbidity and might slow the present decline in per capita food intake. At present the government of Senegal has no population policy and almost no provisions for family planning services. Health services are inadequate and inefficient, with shortages of all levels of health manpower, poor planning, and overemphasis on curative services.
Washington, D.C., U.S. Office of International Health, Division of Planning and Evaluation, 1976. 92 p. (Syncrisis: the dynamics of health, XVII)This article uses available statistics to analyze health conditions in Bangladesh and their impact on the country's socioeconomic development. Background information on the country is first given, after which population characteristics, health status, nutrition, national health policy and adminstration, health services and programs, population programs, environmental sanitation, health sector resources, financing of health care and donor assistance are examined. Bangladesh's 3% annual population increase is expected to increase already great population pressure and to have a negative impact on the health status of the population. Although reliable health statistics are lacking, infant mortality is estimated at 140 per 1000, 40% of all deaths occur in the 0-4 age group, and maternal mortality is high. Infectious diseases exacerbated by malnutrition are the main causes of death. 4 key factors are responsible for the general malnutrition: 1) rapidly growing population, 2) low per capita income, 3) high incidence of diarrheal diseases, and 4) dietary practices that restrict nutrient intake. Most of the population has access only to traditional health services, and medical education is hospital oriental and curative, with minimal emphasis on public health. The level of environmental sanitation is extremely low.

Initiatives in Population 2(1): 28-35. March 1976.The Philippines Department of Labor, in conjunction with the U.N. Fund for Population Activities, is sponsoring a pilot family planning program. The industrial program, supervised by the Labor Management Coordinating Council, aims at integrating family planning services into the health services or clinics of 1000 corporations with at least 200 employees within the 2-year period ending June 1977. Family planning seminars are conducted at 3 levels within the corporations and include training sessions for medical personnel. Companies have found that provision of family planning services is more economical in the long run than provision of family welfare services for employees and families.
