In Brazil relatively little attention is being paid to the study of the features of the spread of the AIDS epidemic towards small cities and rural areas. We report a descriptive study on the epidemiological features of HIV infection among 208 adult patients seen between July 1999 and May 2006 in the municipal HIV/AIDS Programs of three cities of inner Rio de Janeiro State: Saquarema, Santo Antonio de Pádua and Miracema. A portrait of a heterosexual epidemic emerged, with an overall male to female ratio of 1.1. More than 90% were residents of the studied cities, demonstrating a local demand for HIV-related assistance and the importance of municipal HIV/AIDS Programs. Past or current use of snorted cocaine was reported by a quarter of the patients. Older age and male gender were independent predictors of having a diagnosis of AIDS at presentation. The latter is in accordance with a more recent wave of epidemic spread towards female gender. A low frequency of male circumcision, an important determinant of heterosexual HIV transmission, was recorded. Almost 60% of the patients first presented in advanced stages of HIV infection, suggesting the existence of a large pool of undiagnosed cases in the community.

INTRODUCTION: AIDS epidemic has given visibility to the incidence of tuberculosis, for being the most frequent opportunistic infection. It is known that individuals who are socially vulnerable are more susceptible to HIV transmission and tuberculosis as well. OBJECTIVE: This study aims to conduct a geoepidemiological study on HIV/AIDS, AIDS-Tuberculosis co-infection and social vulnerability. METHOD: This is an ecological study using incidence rates and the human development index to produce thematic maps and a descriptive analysis of epidemiology. The records of reported cases of HIV/AIDS from 1982 to 2007 were used, considering as cases of AIDS-Tuberculosis those records that were positively diagnosed with tuberculosis and those records with unknown diagnosis of tuberculosis, but showing compatible signs and symptoms with tuberculosis (fever, cough, cachexia and asthenia). RESULTS: The maps allowed the identification of areas with social differences and different patterns of incidence of HIV/AIDS and AIDS-Tuberculosis; regional differences were similar to those found by Josué de Castro, in 1940; regions with higher human development index values also showed higher incidence HIV/AIDS and AIDS-Tuberculosis. CONCLUSION: The prevention of HIV infection must be geographically specific, given socioeconomic and cultural differences. Although official records show decline in AIDS-TB co-infection, treatment of cases of HIV/AIDS should observe the occurrence of opportunistic diseases, which should be notified and/or updated.

China is facing a major crisis because of the increasing epidemic of HIV/AIDS, especially in the western areas. The purpose of this paper is to enhance understanding of the crisis by analysing the published literature on the epidemiology, demographic features, routes of infection, and risk factors of HIV/AIDS infection in the 12 provinces in the west of China. HIV/AIDS has increased rapidly in recent years. The situation is urgent and requires comprehensive action. China's health care system is decentralized and under-funded, and access to treatment by the poor is seriously limited. There is a lack of knowledge about HIV/AIDS in the general public and health care workers. The HIV/AIDS epidemic emerged initially in western areas of the country by means of intravenous drug use, but sexual risk behaviour and mother-to-child transmissions in the west of China are becoming important for HIV transmission.

A model of the HIV/AIDS epidemic among sex workers and their clients is discussed to study the effects of condom use in the prevention of HIV transmission. The model is addressed to determine the existence of equilibrium states, and then analyze the global stability of disease free and endemic equilibrium states. The global stability of equilibria depends on the vales of the basic reproduction ratio derived from the next generation matrix of the model. The endemic equilibrium state is globally stable when the ratio exceeds unity. The simulation results are presented to discuss the effect of condom use treatment in preventing the spread of HIV/AIDS among sex workers and their clients. The results show that the effectiveness level in using condoms in sexual intercourse corresponds to the decreasing level of the spread of HIV/AIDS. We use Maple and Matlab software to simulate the impact of condom use.

Background As the public sector and civil society develop intervention programs to deal with the HIV/ AIDS epidemic, there has been an increasing emphasis on the relationship between nutrition and the disease. Drug interventions may be ineffective, and the progression from HIV infection to full-blown AIDS may be accelerated without adequate nutrition. Mozambique is still fighting an increasing prevalence rate of HIV, including in rural areas. Rural households in Mozambique rely heavily on their own agricultural production for the basic macronutrients. Objectives To evaluate the extent to which household agricultural production of basic staples meets overall household needs for major macronutrients, comparing households affected and not directly affected by HIV/ AIDS and other major illnesses over two time periods. Methods This research analyzes nationally representative panel data from rural household surveys conducted in 2002 and 2005 to evaluate whether households that have suffered the chronic illness or illness-related death of prime-age adult members (15 to 49 years of age) are more vulnerable to macronutrient gaps. Results Households in the South and in the North with a male illness or death in 2002 produced significantly less macronutrients from crops in 2005 than nonaffected households. These households also had significantly lower income per adult equivalent. Conclusions Mortality or illness from HIV/AIDS affects the ability of agricultural households dependent on own-food production to produce macronutrients. Interventions to improve access to food may be needed for affected households, particularly in light of their inability to recover over time. More analysis is needed to understand income sources, crop diversification, and access to macronutrients through the market.

Significant challenges remain in tackling the global HIV/AIDS epidemic. Effective action requires both appropriate policy at a global level and informed practice on the local level. Here, we report how workers in a project in Johannesburg, South Africa, make sense of HIV transmission. Discourse analysis of data from interviews with 63 participants shows that project workers routinely attribute transmission to men’s sexual relationships with multiple female partners. This explanation is so pervasive that it renders invisible other routes to transmission. Absence of consideration of other routes to infection potentially restricts front-line practice, so hindering local attempts to tackle HIV/AIDS.

OBJECTIVE: Studies on the aspects of HIV infection in small Brazilian municipalities are invaluable to appropriately design control strategies, better allocate resources, and improve health care services. The objective of the study was to assess the clinical and epidemiological aspects of HIV infection in a small municipality. METHODS: A descriptive study was carried out in Miracema, a small municipality in the northwestern area of the state of Rio de Janeiro, Brazil, between July 1999 and December 2003. All HIV-infected adult patients followed up at the local HIV/AIDS Program were included. Clinical and epidemiologic characteristics were prospectively assessed through standardized questionnaires. RESULTS: A total of 65 adult patients who attended the local HIV/AIDS Program were analyzed. Most (34) were women (male to female ratio: 0.9). An absolute predominance of patients who were born in Miracema or neighboring municipalities (94%), lived in Miracema (90.7%), were single (70.8%), attributed the acquisition of HIV infection to unprotected heterosexual intercourse (72.3%) and had a past history of snorting cocaine (27.7) was found Central nervous system disorders (including five cases of cryptococcal meningitis) and acute pulmonary pneumocystosis-like respiratory failure were major causes of morbidity. Most patients (56.9%) were at presented in advanced stages of HIV infection. CONCLUSIONS: The predominance of patients on advanced stages of HIV infection suggest the existence of a large pool of undiagnosed cases in the community. A major feature of the cohort was an inverted male to female ratio. Further investigations over a broader geographic area are urgently needed for better understanding the clinical and epidemiological characteristics of HIV infection in small Brazilian municipalities and rural areas.

Although mother-to-child HIV transmission prevention has slowed down pediatric HIV infection in developed countries, large numbers of infants still become infected in developing nations. Data on pediatric HIV infection is however largely scarce. In this study, we have overviewed clinical, laboratory and genotypic data from a large cohort of HIV-infected infants regularly followed at two pediatric HIV outpatient clinics in Rio de Janeiro, Brazil. Children on antiretroviral therapy, as well as drug-naïve, newly diagnosed infants were analyzed. Prevalence of drug resistance mutations, as well as immunological and virological responses to therapy were evaluated. Additionally, HIV-1 subtype frequencies and their distribution over the course of the epidemic were studied. We have found a high prevalence of mutations among ARV-experienced children, whereas mutations were absent in the drug-naïve group. Despite the high levels of resistance among treated infants, an important improvement of their immunological status was observed. HIV-1 subtype distribution followed the trends of the adult population, with the appearance of non-B subtypes and recombinant forms after 1990. To our knowledge, this is the largest pediatric cohort ever analyzed in Brazil, and the data provided is of paramount importance to a better understanding of HIV/AIDS evolution in pediatric settings.

Botswana has the third highest human immunodeficiency virus (HIV) prevalence globally, and the severity of the epidemic within the country varies considerably between the districts. This study aimed to identify clusters of HIV and associated factors among adults in Botswana. Data from the Botswana Acquired Immunodeficiency Syndrome (AIDS) Impact Survey IV (BIAS IV), a nationally representative household-based survey, were used for this study. Multivariable logistic regression and Kulldorf’s scan statistics were used to identify the risk factors and HIV clusters. Socio-demographic characteristics were compared within and outside the clusters. HIV prevalence among the study participants was 25.1% (95% CI 23.3–26.4). HIV infection was significantly higher among the female gender, those older than 24 years and those reporting the use of condoms, while tertiary education had a protective effect. Two significant HIV clusters were identified, one located between Selibe-Phikwe and Francistown and another in the Central Mahalapye district. Clusters had higher levels of unemployment, less people with tertiary education and more people residing in rural areas compared to regions outside the clusters. Our study identified high-risk populations and regions with a high burden of HIV infection in Botswana. This calls for focused innovative and cost-effective HIV interventions on these vulnerable populations and regions to curb the HIV epidemic in Botswana.

The objective of this article was to evaluate the epidemiology of cryptococcal meningitis in Rio de Janeiro State, Brazil, from 1994 to 2004. Six hundred and ninety-six cases of cryptococcal meningitis were reported, with a mean incidence of 0.45 per 100,000 inhabitants. Patients were predominantly male; mean age was 35.9 years; AIDS was practically the only underlying disease, reported in 61.2% of cases; case-fatality was 51.8%. No decline in incidence was observed during the study period. AIDS is the main predisposing condition for cryptococcal meningitis, and thus the profile of most patients mirrors that of HIV infection. Missing information prevented the evaluation of other underlying diseases.
