    The prevalence of chloroquine-resistant Plasmodium falciparum malaria has been increasing in sub-Saharan Africa and parts of South America over the last 2 decades, and has been associated with increased anaemia-associated morbidity and higher mortality rates. Prospectively collected clinical and parasitological data from a multicentre study of 788 children aged 6-59 months with uncomplicated P. falciparum malaria were analysed in order to identify risk factors for chloroquine treatment failure and to assess its impact on anaemia after therapy. The proportion of chloroquine treatment failures (combined early and late treatment failures) was higher in the central-eastern African countries (Tanzania, 53%; Uganda, 80%; Zambia, 57%) and Ecuador (54%) than in Ghana (36%). Using logistic regression, predictors of early treatment failure included younger age, higher baseline temperature, and greater levels of parasitaemia. We conclude that younger age, higher initial temperature, and higher baseline parasitaemia predict early treatment failure and a higher probability of worsening anaemia between admission and days 7 or 14 post-treatment

    Focus group interviews about AIDS in Rakai district of Uganda

    Focus group interviews about AIDS were held in Rakai district, Uganda during early 1990 with groups from various sections of the community. It was found that the knowledge of AIDS symptoms and its transmission were widespread. Attitudes regarding many aspects of sexual behavior, AIDS patients, condoms, injections, hospital treatment, sexually transmitted diseases and an AIDS cure were investigated. We found that most people no longer fear casual contact with AIDS patients but they blame spouses of people with AIDS for spreading the infection. Condoms are generally not trusted. Many people feel that condoms cannot prevent transmission of the AIDS virus and some fear that they may get torn and cause complications in women. Most people now do not like injections for treatment and when necessary, prefer disposable needles and syringes. Hospital treatment for AIDS patients is not trusted very much, and many people believe that AIDS patients are intentionally killed off by doctors. Sexual behavior was extensively discussed and it was found that there is generally a reduced level of multiple sexual partners. The reduction is more marked in rural areas but the urban areas are still having higher levels of multiple sexual partners

    Evaluating HIV/STD interventions in developing countries: do current indicators do justice to advances in intervention approaches?

    HIV continues to spread unabated in many developing countries. Here we consider the interventions that are currently in place and critically discuss the methods that are being used to evaluate them as reported in the published literature. In recent years there has been a move away from highly individual-oriented interventions towards more participatory approaches that emphasise techniques such as community-led peer education and group discussions. However, this move towards more community orientated intervention techniques has not been matched by the development of evaluation methods with which to capture and explain the community and social changes which are often necessary preconditions for health-enhancing behaviour change. Evaluation research continues to rely on quantitative methodologies that fail to elucidate the complex changes that the newer interventions seek to promote within target communities. In addition, these methods of evaluation tend to rely on the use of highly individualistic and quantitative biomedical indicators such as HIV/STD rates, or knowledge, attitude, perception and behaviour (KAPB) survey questionnaires. We argue that such approaches are inadequate for the task of tracking and measuring important determinants of programme success such as psycho-social changes, features of the community-intervention interface and the degree of trust and identification with which members of target communities regard particular interventions. Rigorously conducted qualitative process evaluations taking account of the above factors could make a key contribution to the development of more successful HIV-prevention interventions
