Reduced rate of disease development after HIV-2 infection as compared to HIV-1.

Human immunodeficiency virus type-2 (HIV-2) is a close relative of the prototype acquired immunodeficiency syndrome (AIDS) virus, HIV-1. HIV-2 is biologically similar to HIV-1, but information is lacking concerning clinical outcomes of HIV-2-infected individuals. From 1985 to 1993, a prospective clinical study was conducted in women with HIV-2 and HIV-1 infection to determine and compare rates of disease development. HIV-1-infected women had a 67% probability of AIDS-free survival 5 years after seroconversion in contrast with 100% for HIV-2-infected women. In addition to having significantly less HIV-related disease outcome in HIV-2 enrollees compared to HIV-1 enrollees, the rate of developing abnormal CD4+ lymphocyte counts with HIV-2 infection was also significantly reduced. This natural history study demonstrates that HIV-2 has a reduced virulence compared to HIV-1.

[Low level educated community health workers training: a strategy to improve children access to acute respiratory treatment in Senegal]. / La formation des agents de santé communautaire instruits: une stratégie pour améliorer l'accès des enfants au traitement des infections respiratoires aiguës au Sénégal.

BACKGROUND: Acute respiratory infections (ARI) are the leading cause of death in childhood. Most of children's deaths happen at home without health level first cares. However in Senegal only health workers are allowed to prescribe antibiotics. A competency-based training was developed to improve and assess the management of acute respiratory infections in young children aged 2 to 59 months by low level educated community health workers (CHWs) in 4 districts of Senegal. The first findings showed the CHWs capable of acquiring the skills needed to effectively manage ARI cases in accordance with the World Health Organization's ARI case management strategy. The aim of this study was to assess the quality of their management after a 1 year follow-up. METHODS: We provided to CHWs 3 days course in ARI management. After the 3-day course, a 4-month follow-up was performed. We organized a 1-day refresher course every month and in every district. In order to assess the quality of management of CHWs we analyzed the management process and compared the CHWs classification to the classification of the first level health facilities. RESULTS: Twenty-three percent (3727/15,965) of IRA cases of district were managed by CHWs. Ninety percent (2738/3042) among them were well classified, well managed and well followed-up. But 28% of severe pneumonia cases were misclassified as pneumonia. About treatment, 22.5% of 'cough or cold' got wrong treatment with cotrimoxazole and 10.3% of severe pneumonia got cotrimoxazole without referral. Less than half of severe pneumonia benefited of the first follow-up and only 18% of the second. CONCLUSIONS: The results highlight that a CHWs low-level educated in French, trained and followed-up could apply the WHO algorithm of IRA management. They could help to give proximal care related to children ARI, to the community. But it seems useful of emphasizing the recognition of danger signs and the follow-up of severe cases.

[Assessment of management training for low-level community health workers providing care for children with acute respiratory infections in four districts of Senegal]. / Formation d'agents de santé communautaire à la prise en charge des infections respiratoires aiguës de l'enfant.

BACKGROUND: Acute respiratory infections are the leading cause of death in childhood and most child deaths in Senegal occur at home without qualified health care. Despite this situation, only qualified healthcare workers are authorized to prescribe antibiotics. A competency-based training program was developed to improve and assess management of acute respiratory infections in young children aged between 2 and 59 months by low-level educated community health workers (CHWs) in four districts of Senegal. METHODS: In accordance with the strategy developed by the World Health Organisation, educated low-level community health workers in four district of Senegal were given a three-day course on the management of acute respiratory failure. We assessed the effects of the course by comparing pre-training and post-training skills with the Students t test. RESULTS: The results showed that the educated low-level community health workers were capable of acquiring the skills needed to effectively manage children with acute respiratory failure. CONCLUSION: Further evaluation is needed to determine the mid- and long-term effects of the course and supervised post-training activities.

Women and family poultry production in rural Africa.

PIP: Poultry production has existed for many generations in Africa, and almost every village household keeps chickens. The rural family poultry (RFP) are generally raised in free-range and/or backyard systems, which are traditional extensive husbandry systems. The development of an intensive poultry production has been the goal of the African government over the years. Despite efforts aiming for such goal, RFP is still very important in African countries that are both poor and net importers of food. It is a valuable asset because it can contribute significantly in alleviating poverty, securing food supply, and promoting gender equality. In view of this, interventions to improve RFP production systems should take into account the sociocultural issues, specifically gender-based aspects. It is noted that such interventions might, in addition to food security and poverty alleviation, also serve to promote gender equality. RFP development programs should be more women-friendly in order to facilitate women's participation, as RFP production in the region is generally a woman's business. Moreover, efforts to empower village women has to be envisaged cautiously as there is a serious risk of men taking over once the poultry sector becomes more profitable.^ieng
