clove and Acquired-Immunodeficiency-Syndrome

The HIV seroprevalence per 100,000 adults Malagasy rose from 20 in 1989, to 30 in 1992, and to 70 in 1995. In that year, the total number of HIV infected people in the Big Island was estimated at 5,000, the number of people sick with AIDS at 130, and the people at risk at more than 1,000,000. The latter are the persons infected with other STDs and individuals (or their partners) with risky sexual behaviour (e.g. numerous sexual partners, occasional sexual partners, and/or sexual contacts with commercial sex workers). The HIV prevalence rate is low as compared with those of other countries. Nevertheless, the spread of the HIV infection is alarming in some parts of the country and the risk factors are also present, namely: the high prevalence of STDs, numerous sexual partners, the low use of condoms in all groups, the development of tourism, the development of prostitution associated with social and economical problems, and internal and international migrations (with risky sexual contacts). Therefore, the still low but rising HIV prevalence in 1995 does not warrant complacency. To estimate the trend of HIV prevalence within the population, it is useful to know two different assumptions, as follows: firstly, a controlled evolution of the epidemic (low epidemic) and secondly, a very fast spread of the epidemic (high epidemic). If we consider the 5,000 individuals seropositive in July 1995, the Aids Impact Model (AIM) projection model shows that HIV seroprevalence rates among adults in 2015 might be between 3% (when the progression course of HIV epidemic is low) and 15% (when the progression course of HIV epidemic is high). By 2015 AIDS could have severe demographic, social, and economic impacts. Then, it is necessary to take measures to prevent contamination. Five major interventions are required: public information about AIDS, HIV transmission mechanism, and its prevention, communities education via the respected people and the notabilities to promote moral values, reduce the number of sexual partners, delay visit of sexual activity, and advice for infected couples; screening of blood donors and the supposed high risk group; control of STDs; reduction of the number of sexual partners; promotion of condom use, abstinence, and fidelity. To sum up, the fight against AIDS is not only the health professional workers' problem. It concerns all Malagasy people. Therefore, successfullness in prevention efforts to slow the epidemic needs concerted, collective, and lon

After an epidemic outbreak, the infection persists in a community long enough to engulf the entire susceptible population. Local extinction of the disease could be possible if the susceptible population gets depleted. In large communities, the tendency of eventual damp down of recurrent epidemics is balanced by random variability. But, in small communities, the infection would die out when the number of susceptible falls below a certain threshold. Critical community size (CCS) is considered to be the mentioned threshold, at which the infection is as likely as not to die out after a major epidemic for small communities unless reintroduced from outside. The determination of CCS could aid in devising systematic control strategies to eradicate the infectious disease from small communities. In this article, we have come up with a simplified computation based approach to deduce the CCS of HIV disease dynamics. We consider a deterministic HIV model proposed by Silva and Torres, and following Nåsell, introduce stochasticity in the model through time-varying population sizes of different compartments. Besides, Metcalf's group observed that the relative risk of extinction of some infections on islands is almost double that in the mainlands i.e. infections cease to exist at a significantly higher rate in islands compared to the mainlands. They attributed this phenomenon to the greater recolonization in the mainlands. Interestingly, the application of our method on demographic facts and figures of countries in the AIDS belt of Africa led us to expect that existing control measures and isolated locations would assist in temporary eradication of HIV infection much faster. For example, our method suggests that through systematic control strategies, after 7.36 years HIV epidemics will temporarily be eradicated from different communes of island nation Madagascar, where the population size falls below its CCS value, unless the disease is reintroduced from outside.

Churches occupy an important social and cultural position in Madagascar. The sexual transmission of HIV raises controversies about the role that Churches can play in preventing HIV/AIDS. This cross-sectional survey investigated recommendations by religious leaders for condom use and other preventive strategies in the context of international guidelines.. A questionnaire was self-administered to a random sample of religious leaders. The questions related to preventive methods against HIV/AIDS such as: condom use, marital fidelity, sexual abstinence before marriage, and HIV-testing. Associations with recommendations for condom use were evaluated using univariate and multivariate logistic regression analyses.. Of 231 religious leaders, 215 (93.1%) were willing to share their knowledge of HIV/AIDS with their congregations. The majority received their information from the media (N=136, 58.9%), a minority from their church (N=9, 3.9%), and 38 (16.4%) had received prior training on HIV. Nearly all (N=212, 91.8%) knew that HIV could be sexually transmitted though only a few (N=39, 16.9%) were aware of mother-to-child transmission or unsafe injections (N=56, 24.2%). A total of 91 (39.4%) were willing to, or had recommended (N=64, 27.7%), condom use, while 50 (21.6%) had undergone HIV testing. Only nine (3.9%) had ever cared for a person living with HIV/AIDS (PLHIV). Multivariable logistic regression shows that condom use recommendations by religious leaders were negatively associated with tertiary level education (OR: 0.3, 95% CI 0.1-0.7), and positively associated with knowing a person at risk (OR: 16.2, 95% CI 3.2-80.2), knowing of an ART center (OR: 2.6, 95% CI 1.4-4.8), and receiving information about HIV at school (OR: 2.6, 95% CI 1.2-5.6).. Malagasy church leaders could potentially become key players in HIV/AIDS prevention if they improved their knowledge of the illness, their commitment to international recommendations, and extended their interaction with people most at risk.

Health care workers are key players in the prevention and management of HIV-infection. We surveyed HIV/AIDS-related knowledge, attitudes and practices of health care workers in Tamatave (Madagascar), to assess the feasibility of voluntary counselling and testing for HIV infection in antenatal care.. A Knowledge Attitude and Practice study was conducted during July 2000 in the antenatal health care centres and the hospital of Tamatave. The health workers completed a self-administrated questionnaire on HIV transmission, attitudes and practices regarding AIDS testing and counselling, HIV risk perception and attitudes regarding patients with HIV disease.. A 90% response rate was obtained, with completed questionnaires from 45 health care workers. The sample included physicians, midwives, nurses, medical students and nursing auxiliaries. Scientific knowledge about transmissibility of HIV infection was poor: transmission was believed possible by living together without having sex (7%), by breastfeeding a HIV-positive child (9%), by using toilets after a HIV-positive patient (13%) and by blood donation (76%). 73% of the health staff believed a child born of an HIV-positive woman would systematically be infected and interventions to reduce this risk were unknown. Sixty one per cent of the health-workers reported never having advised patients to be tested and less then 10% mentioned correct counselling precautions. Seventy nine percent believed that they were at risk of acquiring AIDS, mainly through occupational exposure. Negative attitudes towards HIV-positive patients were also noted: twenty per cent of the health workers mentioned that AIDS patients should be isolated in quarantine. Physicians and paramedical staff differed only in their better knowledge about transmissibility of HIV. Physicians had the same restrictive attitude towards patients with HIV as paramedical health workers and did not differ by their counselling practice.. Our study revealed gaps in the knowledge of health care workers about HIV infection. Before implementing voluntary counselling and testing in antenatal care, additional HIV/AIDS training for health staff seems necessary.

Madagascar is still among the rare states of low prevalence of HIV. The seroprevalence rate is nevertheless rising. The aim of this study is to show the current view of the epidemic, its future tendency, its economical and social impact on people and what measures to be taken at the national scale. In Madagascar, we can state by 1995 20 cases of notified AIDS and probably 130 cases of non-notified AIDS. Seroprevalence data are collected every year by the National Reference Laboratory STD/AIDS. But, they are insufficient to estimate the number of infected people. So, they had been completed by a serosurveillance study of AIDS and syphilis in middle of 1995 and at the beginning of 1996. Pregnant women, persons with STDs and prostitutes are been screened in the six biggest cities of the Island. Results show, not only a high prevalence of syphilis, but also indicate that now, we have about 5,000 seropositive people in the country. Besides, by the number of people with STDs, it is estimated that one million Malgasy adults risk to be infected. Based on estimates of the epidemic, be it the cases of a high scenario, (Kenya) or of a low one (Thailand) by the year 2015, the seroprevalence rate could represent 3% or 15% of adults. Demographic consequences of the epidemic will be serious, particularly if HIV spreads quickly. Nevertheless, it does not stop the increase of population. Therefore, there will be more infected people with the disease, especially young people between 15 and 49 years old. The increase of dead people will be serious. Social consequences of the epidemic (case of high scenario) will be gravely felt, in particular by the rise of the number of AIDS orphans. Tuberculosis outbreak can be observed too. This disease is already a serious problem in Madagascar. At last, the epidemic will bring with it a high increase of money spent on health and will have grave consequences on agriculture, industry and commerce. Nevertheless, Madagascar still benefit a big luck which is the prevention of the epidemic not to be exploded in a near future. For this, struggle against it is particularly effective on its start. In addition to counselling given to infected people and care-given to patients, means of prevention of AIDS contamination in all target groups must be set up quickly. It is about broadcasting information on AIDS, community education, controlling other STDs e.g. (importance of medicaments' program), promoting the use of condoms and screening HIV new ca. Studies were conducted in mid-1995 and at the beginning of 1996 in six sites in Madagascar on the seroprevalences of HIV and syphilis with the goal of estimating how many people were infected with HIV countrywide. The studies were conducted in Antananarivo, Fianarantsoa, Antsiranana, Toamasina, Toliary, and Mahajanga. 3135 pregnant women seeking prenatal care were included in the study, as well as 3047 sexually transmitted disease (STD) clinic clients, and 2227 prostitutes not registered with the STD services, but recruited in bars, hotels, and on the street. Study data together with epidemiological surveillance data led to the estimation that 0.07% of adults in the country were infected with HIV as of 1995, compared with 0.02% in 1989. There were 150 people with AIDS, 5000 people infected with HIV, and 1 million people at risk of exposure to the virus. In Madagascar, HIV is transmitted sexually in 96.8% of cases, perinatally in 2.4% of cases, and through blood transfusion in 0.8% of cases. As many men as women are infected, and 64% of all people infected with HIV are 20-39 years old. Projecting the course of the epidemic into the future, 3-15% of the country¿s adults could be infected with HIV in the year 2015, bringing seriously negative demographic and socioeconomic consequences. Madagascar¿s population will, however, continue to grow even should HIV be widely disseminated throughout the country. It is not too late for Madagascar to take measures to avert a major HIV/AIDS epidemic among its peoples.
