ABSTRACT
ABSTRACT OBJECTIVE To describe the increase in cases of malaria in Mozambique. METHODS Cross-sectional study conducted in 2014, in Mozambique with national weekly epidemiological bulletin data. I analyzed the number of recorded cases in the 2009-2013 period, which led to the creation of an endemic channel using the quartile and C-Sum methods. Monthly incidence rates were calculated for the first half of 2014, making it possible to determine the pattern of endemicity. Months in which the incidence rates exceeded the third quartile or line C-sum were declared as epidemic months. RESULTS The provinces of Nampula, Zambezia, Sofala, and Inhambane accounted for 52.7% of all cases in the first half of 2014. Also during this period, the provinces of Nampula, Sofala and Tete were responsible for 54.9% of the deaths from malaria. The incidence rates of malaria in children, and in all ages, have showed patterns in the epidemic zone. For all ages, the incidence rate has peaked in April (2,573 cases/100,000 inhabitants). CONCLUSIONS The results suggest the occurrence of an epidemic pattern of malaria in the first half of 2014 in Mozambique. It is strategic to have a more accurate surveillance at all levels (central, provincial and district) to target prevention and control interventions in a timely manner.
RESUMO
RESUMO OBJECTIVO Descrever o aumento de casos de malária em Moçambique. MÉTODOS Estudo transversal conduzido em 2014, em Moçambique com dados do boletim epidemiológico semanal nacional. O número de casos registrados no período de 2009 a 2013 foi analisado e um canal endêmico foi criado usando o método de quartil e C-Sum. Taxas de incidência mensal foram calculadas para o primeiro semestre de 2014, permitindo determinar o padrão de endemicidade. Meses em que as taxas de incidência ultrapassaram o terceiro quartil ou a linha C-Sum foram declaradas como meses epidêmicos. RESULTADOS As províncias de Nampula, Zambézia, Sofala e Inhambane foram responsáveis por 52,7% de todos os casos no primeiro semestre de 2014. Também durante esse período, as províncias de Nampula, Sofala e Tete foram responsáveis por 54,9% das mortes por malária. As taxas de incidência da malária em crianças, e todas as idades, registaram padrões na zona de epidemia. Para todas as idades, a taxa de incidência registou um pico em abril (2.573 casos/100 mil habitantes). CONCLUSÕES Os resultados sugerem a ocorrência de um padrão epidêmico de malária no primeiro semestre de 2014 em Moçambique. É de importância estratégica haver vigilância mais acurada e em todos os níveis (distrital, provincial e central), para direccionar as intervenções de prevenção e controle em tempo útil.
