The English-speaking Caribbean is in transition toward communicable disease health patterns seen in the more developed world. Structural adjustment policies in recent years have weakened control measures, such as water supply and sanitation, as illustrated by recent outbreaks of typhoid fever in Jamaica (1990-1991), increased malaria incidence in Suriname and Guyana (with temporary importation into southern Trinidad in 1991), an upswing in tuberculosis in some countries, and the occurrence of cholera outbreaks in Belize, Suriname, and Guyana. The emergence of epidemic cholera throughout most of Latin America in 1991, and Caribbean mainland countries in 1992, aroused concern. Deteriorating socioeconomic conditions and the consequent communicable disease risk underscored the absence of communicable disease control in the Caribbean Cooperation in Health (CCH) strategy which was adopted in 1986 by the countries of the Caribbean Community. The Caribbean Epidemiology Center (CAREC) offered the following analysis: At least four out of seven CCH priorities already directly address critical aspects of communicable disease control, and therefore the question arises whether communicable disease control should be recognized as an explicit CCH priority. Beyond cholera and the diseases already represented in the CCH strategy, there are only a few other communicable diseases that warrant specific attention at this time: tuberculosis; leprosy, which CAREC member countries may want to eradicate; and leptospirosis, a zoonosis (communicable disease of animals transmissible to humans) thought to be the most frequent disease of this type in the Caribbean. These three conditions are insufficient to justify a distinct communicable disease grouping within CCH. However, if all communicable diseases of public health importance were to be grouped together (AIDS/STD, vaccine-preventable diseases, food- and waterborne diseases, vector-borne diseases), such a group would be important enough to justify a distinct priority category, with several major subcategories.

In the unique environment of Australia's tropical north there are endemic diseases inherited from Gondwana, others introduced from the north and from Europe, and a wide range of particularly venomous animals. There is continuing disparity in morbidity and mortality between Aboriginal people and other Australians in tropical areas and elsewhere. This is being addressed by the National Aboriginal Health Strategy, which emphasises social, environmental and economic issues, as well as control and coordination of services by Aboriginal and Torres Strait Islander communities. While the re-introduction of malaria remains a potential threat, together with other infections, current diseases in tropical Australia are being better elucidated; melioidosis is now recognised as the commonest cause of fatal [corrected] community-acquired pneumonia in the Top End of the Northern Territory, and a new focus of scrub typhus has been found. Sexually transmitted diseases are an urgent issue, especially for Aboriginal communities, given the potential impact of the human immunodeficiency virus.

Without a medical miracle, it seems inevitable that the Acquired Immune Deficiency Syndrome (AIDS) pandemic will become not only the most serious public health problem of this generation but a dominating issue in 3rd world development. As a present-day killer, AIDS in developing countries is insignificant compared to malaria, tuberculosis, or infant diarrhea, but this number is misleading in 3 ways. First, it fails to reflect the per capita rate of AIDS cases. On this basis, Bermuda, French Guyana, and the Bahamas have much higher rates than the US. Second, there is extensive underreporting of AIDS cases in most developing nations. Finally, the number of AIDS cases indicates where the epidemic was 5-7 years ago, when these people became infected. Any such projections of the growth of 3rd world AIDS epidemics are at this time based on epidemiologic data from the industrialized rations of the north and on the assumption that the virus acts similarly in the south as it does in the US and Europe. Yet, 3rd world conditions differ. Sexually transmitted diseases usually are more prevalent, and people have a different burden of other diseases and of other stresses to the immune system. In Africa, AIDS already is heavily affecting the mainstream population in some nations. Some regions will approach net population declines over the next decade. How far their populations eventually could decline because of AIDS is unclear and will depend crucially on countermeasures taken or not taken over the next 1-2 years. In purely economic terms, AIDS will affect the direct costs of health care, expenses which are unrealistic for most 3rd world countries. Further, the vast majority of deaths from AIDS in developing countries will occur among those in the sexually active age groups -- the wage earners and food producers. Deaths in this age group also will reduce the labor available for farming and industry. AIDS epidemics also may have significant effects on foreign investment in the 3rd world as well as negative effects on tourism. The global underclass will be disproportionately affected by AIDS as the blacks and Hispanics already are in New York and Miami. Thus far, the reaction of donor countries to the World Health Organization's (WHO) appeal for funds to fight the battle against AIDS has been excellent. The global strategy of WHO places priority on national campaigns, but none of the national campaigns will be effective unless linked to similar actions in other nations to form a vigorous international program. The US has a special responsibility to provide international leadership on AIDS. The US is the world leader in AIDS research and has the bulk of the virus research capacity. Further, no country can come close to matching US experience in dealing with AIDS through "safe sex" education campaigns.

Nomadic and seminomadic pastoralists make optimal use of scarce water and pasture in the arid regions south of the Sahara desert, spreading from Mauretania in the west to Somalia in East Africa. We attempted to summarize the fragmentary evidence from the literature on the health status of these populations and to assess the best ways to provide them with modern health care. Infant mortality is higher among nomadic than among neighbouring settled populations, but childhood malnutrition is less frequent. Nomads often avoid exposure to infectious agents by moving away from epidemics such as measles. Trachoma is highly prevalent due to flies attracted by cattle. The high prevalence of tuberculosis is ascribed to the presence of cattle, crowded sleeping quarters and lack of health care; treatment compliance is generally poor. Guinea worm disease is common due to unsafe water sources. Helminth infections are relatively rare as people leave their waste behind when they move. Malaria is usually epidemic, leading to high mortality. Sexually transmitted diseases spread easily due to lack of treatment. Leishmaniasis and onchocerciasis are encountered; brucellosis occurs but most often goes undetected. Drought forces nomads to concentrate near water sources or even into relief camps, with often disastrous consequences for their health. Existing health care systems are in the hands of settled populations and rarely have access to nomads due to cultural, political and economic obstacles. A primary health care system based on nomadic community health workers is outlined and an example of a successful tuberculosis control project is described. Nomadic populations are open to modern health care on the condition that this is not an instrument to control them but something they can control themselves.

In this study, a questionnaire was used to study the individual behavior of a sample of fifty health workers, doctors and nurses from Tamatave (Madagascar) with respect to a number of current health issues. We used the results to assess the impact and efficacy of previous training and to obtain information about the extent to which health staff actually follow the recommendations and standards that they are given and expected to teach, as far as their own health is concerned. It was clear that the standard management procedures and instructions concerning basic health-preserving behavior were far from being universally accepted and followed by health workers themselves. This was the case even for common diseases and health issues for which specific training had been given, such as malaria, diarrhea, AIDS and STDs, tobacco use, HBP management and the use of antibiotics. More attention should be paid to involving health workers in their training programs so that they are really convinced by the recommendations given. So long as most health workers are not themselves committed to the recommendations and have inadequate behavior regarding their own health, they are unlikely to be effective at promoting good health practice.

The authors studied a population of 5634 students from various continents to determine possible correlations between risk factors and seroprevalence of HIV infection. In the African sample the seroprevalence rate was 3.5%; the age range from 19 to 30 years was most affected; prevalence differences between the sexes were slight (3.5% for the males vs 3% for the females); the evaluation of the medical history (STDs, malaria, TB and hospital stays) showed no statistically significant association with HIV-1 infection; the central-eastern Africa significantly appeared the most affected.

This study evaluated the HIV prevalence and identified the risk factors for HIV infection among women attending the antenatal clinic at a public hospital in Kisumu, western Kenya. Also, the effect of placental malaria on vertical HIV transmission were determined using structured interviews and HIV-1 antibody testing and hemoglobin malaria smears were offered to the respondents. Overall, HIV seroprevalence was 26.1% (743/2844) (95% confidence interval [CI]: 24.5-27.7) and in bivariate evaluation was significantly associated with anemia (risk ratio [RR] 1.8), malarial parasitemia (RR 1.6), fever (RR 1.6), a history of being treated for either vaginal discharge (RR 1.5) or tuberculosis (RR 1.6), alcohol consumption (RR 1.6), being an unmarried multigravida (RR 2.2), or a history of the most recent child having died (RR 2.0). Using the Poisson regression analysis, 5 significant factors associated with HIV seropositivity were identified: anemia, malarial parasitemia, and history of being treated for vaginal discharge, fever, and reported alcohol consumption. Among the pregnant women, the researchers were unable to identify a subgroup at risk of HIV infection using nonserological information, indicating that universal access to voluntary HIV counseling and testing would be preferable to targeted screening.

The economic crisis in Thailand in July 1997 had major social implications for unemployment, under employment, household income contraction, changing expenditure patterns, and child abandonment. The crisis increased poverty incidence by 1 million, of whom 54% were the ultra-poor. This paper explores and explains the short-term health impact of the crisis, using existing data and some special surveys and interviews for 2 years during 1998-99. The health impacts of the crisis are mixed, some being negative and some being positive. Household health expenditure reduced by 24% in real terms; among the poorer households, institutional care was replaced by self-medication. The pre-crisis rising trend in expenditure on alcohol and tobacco consumption was reversed. Immunization spending and coverage were sustained at a very high level after the crisis, but reports of increases in diphtheria and pertussis indicate declining programme quality. An increase in malaria, despite budget increases, had many causes but was mainly due to reduced programme effectiveness. STD incidence continued the pre-crisis downward trend. Rates of HIV risky sexual behaviour were higher among conscripts than other male workers, but in both groups there was lower condom use with casual partners. HIV serosurveillance showed a continuation of the pre-crisis downward trend among commercial sex workers (CSW, both brothel and non-brothel based), pregnant women and donated blood; this trend was slightly reversed among male STD patients and more among intravenous drug users. Condom coverage among brothel based CSW continued to increase to 97.5%, despite a 72% budget cut in free condom distribution. Poverty and lack of insurance coverage are two major determinants of absence of or inadequate antenatal care, and low birthweight. The Low Income Scheme could not adequately cover the poor but the voluntary Health Card Scheme played a health safety net role for maternal and child health. Low birthweight and underweight among school children were observed during the crisis. The impact of the crisis on health was minimal in some sectors but not in the others if the pre-crisis condition is efficient and healthy and vice versa. We demonstrated some key health status parameters during the 2-year period after the 1997 crisis but do not have firm conclusions on the impact of the economic crisis on health status, as our observation is too short and there is uncertainty on how long the crisis will last.

The global challenge of optimally treating bacterial infections is continuously evolving. Azithromycin, the first azalide antibiotic, presents pharmacokinetics and pharmacodynamics that allow for a simple dosing regimen with minimal side effects. Current azithromycin uses include a variety of community-acquired respiratory tract, skin and soft tissue, and sexually transmitted disease infections. Azithromycin has also demonstrated substantial activity against atypical organisms such as Mycobacterium avium complex (MAC) and Chlamydia trachomatis. Due to a never-ending need for new antibiotic therapies, several other potential indications for azithromycin are being researched. This article will present various current research associated with azithromycin's potential use for malaria, trachoma, coronary artery disease (CAD), Pseudomonas aeruginosa infections, erythema migrans, short-term therapy for respiratory infections, typhoid, cryptosporidiosis, pelvic inflammatory disease, acne, Mediterranean spotted fever and MAC. As bacterial and parasite resistance patterns fluctuate globally, azithromycin may be an alternative therapy for the previously mentioned indications, which will also enhance patient compliance and therefore effectively eradicate infection worldwide.

Prenatal care has been implemented in developing countries according to the same mode as applied in industrialized countries without considering its real effectiveness in reducing maternal and neonatal mortality. Several recent studies suggest that the goals should be revisited in order to implement a program of prenatal care based on real scientific evidence. Based on the current literature, we propose a potentially effective content for prenatal care adapted to the context of developing countries. Four antenatal consultations would be enough if appropriately timed at 12, 26, 32 and 36 weeks pregnancy. The purpose of these consultations would be: 1) to screen for three major risk factors, which, when recognized, lead to specific action: uterine, scare, malpresentation, premature rupture of the membranes; 2) to prevent and/or detect (and treat) specific complications of pregnancy: hypertension, infection (malaria, venereal disease, HIV, tetanus, urinary tract infection); anemia and trace element deficiencies, gestational diabetes mellitus; 3) to provide counseling, support and information for pregnant women and their families (including the partner) concerning: severe signs and symptoms of pregnancy and delivery, community organization of emergency transfer, delivery planning. These potentially effective actions can only have a real public health impact if implemented within an organized maternal health system with a functional network of delivery units, if truly quality care is given, and if the relationships between health care providers and the population are based on mutual respect. Sub-Saharan African women use prenatal care extensively when it is accessible; this opportunity must be used to implement evidence-based actions with appropriate and realistic goals.
