RESUMO
Background. A universal goal of public health is to ensure that adolescents have a healthy transition to adulthood. In developing countries, a host of social, economic and political factors inhibit this from happening. The results of these challenges include an increasing disease prevalence among an age group (10 - 19-year-olds) that should be healthy. Objectives. The purpose of this study is to identify the most prevalent diseases and assess the relationship between disease and grade repetition among adolescents in South Africa (SA), and to assess the impact of disease on grade repetition. Methods. Data from the SA General Household Surveys (2009 - 2016) were analysed, and both adolescent (10 - 19 years) sexes from all geographical and racial groups were included. Frequencies, percentages and rates of infectious, non-communicable diseases (NCDs) and mental health outcomes were estimated. The relationship between disease and grade repetition was determined using logistic regression. Results. Infectious diseases, NCDs and mental illnesses are increasing in adolescents over time. In urban areas, rates of NCDs are higher than those of infectious diseases, while in rural areas a high burden of infectious disease persists. Among adolescents who repeated a grade, 7.07% had an infectious disease. In addition, infectious disease (odds ratio (OR) 1.17, p<0.05), younger adolescents, 15 - 19-year-olds (OR 1.52, p<0.05) and urban residence (OR 1.12, p<0.05) are associated with increased likelihood of grade repetition. Conclusion. Policies and programmes in SA which address the health of adolescents need to be more aware of the disease prevalence among school pupils in the country. Prolonged disease occurrences are contributing to the slow school progression and eventual matriculation of pupils

"Epidemic detection algorithms are being increasingly recommended for malaria surveillance in sub-Saharan Africa. We present the results of applying three simple epidemic detection techniques to routinely collected longitudinal pediatric malaria admissions data from three health facilities in the highlands of western Kenya in the late 1980s and 1990s. The algorithms tested were chosen because they could be feasibly implemented at the health facility level in sub-Saharan Africa. Assumptions of these techniques about the normal distribution of admissions data and the confidence intervals used to define normal years were also investigated. All techniques identified two ""epidemic"" years in one of the sites. The untransformed Cullen method with standard confidence intervals detected the two ""epidemic"" years in the remaining two sites but also triggered many false alarms. The performance of these methods is discussed and comments are made about their appropriateness for the highlands of western Kenya."

El trabajo analiza, partiendo de fuentes primarias, las principales enfermedades registradas en una muestra de 4 446 esclavos existentes en La Habana a fines del siglo XVI y durante el siglo XVII (1580-1699). Se calcularon índices de morbilidad por sexo, grupos etáreos y otras categorías de interés; los mayores índices se encontraron entre los esclavos vinculados a la producción azucarera, los menores entre los africanos recién introducidos en la Isla. Asimismo se intentó identificar las diferentes enfermedades mediante la utilización de los textos médicos de la época
