Swaziland is a kingdom with 800,000 inhabitants bordering on Mozambique and South Africa with about 50% of the population under 15 years of age. The experience of a nurse in a small clinic in the course of several years is recounted. Swaziland ranks 3rd in the world in alcohol abuse which often leads to wounds requiring suturing. Penicillin is given prophylactically with a paracetamol preparation for analgesia. As a rule, every injured person will get a .5 ml tetanus injection for prophylaxis. The most serious conditions of polyclinic patients are hepatitis, bilharzia, diarrhea, pellagra, pneumonia, and malnutrition. A great number of patients have sexually transmitted diseases, and the rate of AIDS infection is not known. According to 1 study 60-80% of the population in reproductive age will die of AIDS in the course of a 5-year period. The majority of people are impervious to counseling about their sexual behavior in spite of educational programs on the radio, in schools, and in work places. Condoms are not popular, since they are not considered manly. Pregnant women receive iron and multivitamin tablets in the course of pregnancy. Many pregnant women are anemic, and 70% give birth at home, the rest in a hospital or clinic. During delivery they get no analgesia, and there are few complications. The average weight of the newborn is 3.5 kg, although none of the women are under 150 cm. A little after birth all children are vaccinated with bacillus Calmette-Guerin (BCG) and polio, later with diphtheria-pertussis-tetanus (DPT) and measles.

A National Serum Bank was established to store sera obtained during the National Seroepidemiological Survey performed in Mexico in 1987. More than 70,000 serum samples were obtained from subjects of either sex 1-99 years of age in each of the 32 states of the country. The current collection of sera includes 28,704 male samples and 40,629 female samples. This paper describes the procedures for handling serum samples, including reception registry, storage and distribution to several laboratories for detection of measles, rubella, poliomyelitis, AIDS, diphtheria, pertussis, tetanus, brucella, salmonella, amoeba, toxoplasma, American trypanosomiasis and cysticercus. Determinations of total cholesterol were also made in order to describe its distribution and to identify the prevalence of hypercholesterolemia.

We evaluated the participation of Louisiana physicians in the reporting of communicable diseases. In the spring of 1990 we surveyed a stratified random sample of Louisiana physicians from specialties likely to see patients with reportable diseases. Between 30% and 67% of physicians indicated that they reported all the cases of the queried diseases they had seen during the past year. The proportion reporting all cases differed by disease. AIDS and pertussis were always reported by more than half of the respondents. Mumps was least reported. Perceived barriers and suggestions to improve reporting are discussed.

Communicable diseases represent a considerable burden in terms of suffering and costs. The decision to develop a new vaccine varies with perspectives. The public health perspective is influenced largely by cost-benefit ratios; the community perspective by a strong desire to alleviate suffering and disability from disease and from vaccine side-effects; and that of vaccine producers by demand, technological feasibility of development, and anticipated return on investment. Each of these perspectives is important. However, they often are mutually exclusive. From a humanitarian and epidemiological perspective, the most urgent needs related to communicable diseases are those of the poorest countries; in the industrialised world, with the exception of the vaccine for the acquired immunodeficiency syndrome (AIDS), public health priorities, evaluated in terms of the cost-benefit ratio, often differ from those of the market, which usually selects its priorities according to return on investment. The six vaccines used in the Expanded Programme of Immunisation (EPI) are offered cheaply through a highly efficient bidding system. It would have to be extended, under the same form or differently, to other vaccines, such as those for rabies, hepatitis B, or japanese encephalitis. For vaccines that are being developed, such as conjugated polysaccharide or acellular pertussis vaccines, it is difficult to foresee how these expensive vaccines can be distributed. The situation is even worse for vaccines to be developed specifically for the third world. To make these vaccines available to everyone there must be technology that enables producers to sharply reduce production costs, and a subsidy for research and development and production.

We isolated Bordetella pertussis from three patients with acquired immunodeficiency syndrome who underwent diagnostic bronchoscopy for evaluation of respiratory symptoms. The B. pertussis isolates were recovered from medium (charcoal-yeast extract agar) formulated to enhance recovery of Legionella spp., and one of the isolates stained positively with antisera directed against Legionella spp.

Ethiopia is a country of 45 million people in northeast Africa. With a stagnant, agriculture-based economy and a per capita gross national product of $110 in 1984, it is one of the world's poorest nations. 70% of the children are mildly to severely malnourished, and 25.7% of children born alive die before the age of 5. Life expectancy is 41 years. The population is growing at the rate of 2.9%/year, but only 2% of the people use birth control. After the 1974 revolution, the socialist government nationalized land and created 20,000 peasant associations and kebeles (urban dwellers' associations), which are the units of local government. The government has set ambitious goals for development in all sectors, including health, but famine, near famine, forced resettlement programs, and civil war have prevented any real progress from being made. The government's approach to health care is based on an emphasis on primary health care and expansion of rural health services, but the Ministry of Health is allocated only 3.5% of the national budget. Ethiopia has 3 medical schools -- at Addis Ababa, Gondar, and the Jimma Institute of Health Sciences. Physicians are government employees but also engage in private practice. A major problem is that a large proportion of medical graduates emigrate. Ethiopia has 87 hospitals with 11,296 beds, which comes to 1 bed per 3734 people. There are 1949 health stations and 141 health centers, but many have no physician, and attrition among health workers is high due to lack of ministerial support. Health care is often dispensed legally or illegally by pharmacists. Overall, there is 1 physician for 57,876 people, but in the southwest and west central Ethiopia 1 physician serves between 200,000 and 300,000 people. In rural areas, where 90% of the population lives, 85% live at least 3 days by foot from a rural health unit. Immunization of 1-year olds against tuberculosis, diphtheria-pertussis-tetanus, poliomyelitis, and measles is 11, 6, 6, and 12% respectively. Infectious diseases dominate the medical scene in Ethiopia. In 1984, tuberculosis accounted for 11.2% of hospital admissions and 12.2% of deaths. The leading cause of childhood mortality in 1984 was diarrhea (45%). Malaria, trypanosomiasis, schistosomiasis, leishmaniasis, and meningococcal meningitis are endemic. Intestinal parasitism is rampant, and the nationwide prevalence of leprosy is 3/1000. Venereal diseases were the 9th most common cause of hospital outpatient visits in 1984, but AIDS is rare. The leading noninfectious diseases are rheumatic and syphilitic heart disease, hypertension, diabetes mellitus, hepatoma, and elephantiasis. Ethiopia has the highest number of cases of nonfilarial elephantiasis -- an estimated 350,000 cases -- in the world. Aside from a large influx of money, the most necessary changes to improve the health system are lowering the salaries of doctors and nurses, reorienting physician training toward primary health care, increasing the quality of existing health services, more efficient management, and better coordination between the Ministry of Health and the voluntary organizations.

This paper opens by briefly tracing the development of vaccines from Edward Jenner's work in 1796 to the present. The proportion of deaths from communicable diseases in developed and developing countries is discussed, and it is noted that, in 1990, communicable diseases killed 575,000 people in industrialized countries and 16 million people in developing countries. In developed countries, there were no deaths from measles, malaria, tetanus, or pertussis, and only seven from diarrheal disease as compared to 1,006,000, 926,000, 505,000, 321,000, and 2,866,000, respectively, in developing countries. By the end of the century, AIDS will overshadow the communicable disease profile. Annual mortality figures from bites by rabid animals, snakes, insects, etc. are also grossly underreported. A look at the common biologicals used in developing countries shows that at least eight bacterial and eight viral vaccines are in common use globally. The origin and indications for each vaccine are tabulated. Data on anti-serum vaccines, plasma-derived preparations, and biological response modifiers (available in industrialized countries) are similarly tabulated. Consideration of the industrial production of immunogens in developing countries reveals that most production relies on outdated technology. Vaccines exhibit suboptimal performance in these settings either due to factors relating to individual vaccines or to community circumstances. Individual vaccines which exhibit inadequate potency in adverse circumstances include liquid vaccines and lyophilized vaccines and prophylactics. This situation is exacerbated by unsatisfactory vaccine administration practices, malnutrition, and cases of immunosuppression. Suboptimal performance at the community level is due to procurement procedure, the cost of vaccines, poverty, population growth, failures in the cold chain, lack of trained personnel, religion and gender bias, and political factors, such as war. A suitable remedial action plan requires integrated action at the international, national, and community levels. Such an effort would be aided by improved mortality data collection techniques and by multidisciplinary research to update indigenous manufacturing technology.

A 60-year-old heterosexual man with AIDS was admitted to hospital with dyspnea, a severe paroxysmal non-productive cough of two months' duration, low-grade fever and exhaustion. Bordetella pertussis was cultured from a bronchoalveolar lavage specimen. After erythromycin therapy (500 mg q.i.d. for two weeks) all respiratory symptoms resolved progressively over a four-week period. Bordetella pertussis should be added to the long list of pathogens that may cause respiratory disease in persons with HIV infection.

Despite improvements in infant mortality, 500,000 infants die every year in the Americas. In Costa Rica, child mortality dropped from 68/1000 live births in 1970 to 20/1000 in 1980 as a result of improved hygiene and nutrition, immunization, and treatment. In most other countries of the Americas, infant mortality rates have declined substantially mainly because of public health programs. Educational levels of mothers and per capita national product also exert a notable influence on infant mortality. Poverty inflicts health problems: 177 million children are malnourished, and 40% of children in developing countries are undernourished, a state of affairs responsible for almost 60% of infant deaths. Breast-feeding plays a vital role in the first year of life by providing high quality nutrition and immunological protection, and emotional bonding between the mother and the child. Unfortunately, breast-feeding prevalence and duration is on the decline in developing countries. Safe drinking water and good sanitation are crucial in preventing and reducing child mortality. Women who become pregnant at either extreme of the reproductive age are exposed to higher maternal and pediatric risks; so are multiparous women, and women with short birth intervals. Most child deaths between the ages of 1-4 are preventable by health intervention: the main causes are diarrheal and respiratory diseases, malnutrition, and vaccine-preventable infectious diseases. Intestinal infections cause almost 5 million child deaths a year, and oral rehydration therapy is the most effective preventive measure. Vaccination is the most effective means of preventing measles, polio, tetanus, diphtheria, tuberculosis, and pertussis. In many countries, malaria has resurfaced with some 250-300 million new cases every year. Children and pregnant women are especially vulnerable to suffer serious complications. There were a quarter million cases of cholera in the Americas between early 1991 and August, 1992. AIDS is also a threat to child health because of the rising numbers of infected mothers and pregnant women.

The ability of CD8 T cells derived from human immunodeficiency virus (HIV)-infected patients to produce soluble HIV-suppressive factor(s) (HIV-SF) has been suggested as an important mechanism of control of HIV infection in vivo. The C-C chemokines RANTES, MIP-1 alpha and MIP-1 beta were recently identified as the major components of the HIV-SF produced by both immortalized and primary patient CD8 T cells. Whereas they potently inhibit infection by primary and macrophage-tropic HIV-1 isolates, T-cell line-adapted viral strains tend to be insensitive to their suppressive effects. Consistent with this discrepancy, two distinct chemokine receptors, namely, CXCR4 (ref. 7) and CCR5 (ref. 8), were recently identified as potential co-receptors for T-cell line-adapted and macrophage-tropic HIV-1 isolates, respectively. Here, we demonstrate that the third hypervariable domain of the gp 120 envelope glycoprotein is a critical determinant of the susceptibility of HIV-1 to chemokines. Moreover, we show that RANTES, MIP-1 alpha and MIP-1 beta block the entry of HIV-1 into cells and that their antiviral activity is independent of pertussis toxin-sensitive signal transduction pathways mediated by chemokine receptors. The ability of the chemokines to block the early steps of HIV infection could be exploited to develop novel therapeutic approaches for AIDS.
