The proportion of people with AIDS is increasing rapidly in Zimbabwe. Several strategies have been adopted to check the further spread of the disease. This paper discusses the behaviour patterns which may predispose to HIV infection and possible intervention strategies that may be taken in the City of Harare. ⋯ Forty eight pc of the married respondents who have engaged in casual sexual relationships never use condoms. The main source of information on AIDS/HIV was the radio (74 pc). Most parents (66 pc) had not talked about AIDS to their children.

Randomized Controlled Trial Clinical Trial
Divergent mortality for male and female recipients of low-titer and high-titer measles vaccines in rural Senegal.
The female/male mortality ratio among unimmunized children and children vaccinated with standard or high-titer measles vaccines was examined for all children born in the period 1985-1991 in a rural area of Senegal. The female/male mortality ratio from 9 months to 5 years of age for unvaccinated children was 0.94 (95% confidence interval (CI) 0.75-1.19), significantly different from the ratio of 0.64 (95% CI 0.48-0.85) for recipients of the Schwarz standard measles vaccine (p = 0.040). ⋯ Hence, the Schwarz standard and high-titer measles vaccines have divergent sex-specific effects on mortality throughout childhood. Further studies of the underlying mechanisms are needed.

Basic investigation in industrial laboratories are mainly addressed to widespread diseases. It follows that: 1) basic research is addressed chiefly to the well known and largely diffuse diseases; 2) rare diseases are not usually studied and therefore little chance is given to their physiopathological or therapeutic knowledge. Hence the name of orphan diseases. ⋯ Therefore we suggest starting from a study plane, classification and estimation of rare diseases, shared for apparatus. These studies may be undertaken on a vigorous rationale (more than studies on orphan drugs) and therefore they may bring about to the definition of a national (government) planning for addressing consistent financial resources to the study of pathophysiology and therapy (or prevention) of the major orphan diseases. Adequate studies within the European Community may be planned in the near future, since most rare diseases are presumed to have a common distribution within the Community.
