ABSTRACT

Introduction: malaria is one of the biggest health problems in Angola. This disease is endemic in the whole country, which is divided into several epidemiological strata, depending on the transmission intensity.
Objective: to describe the actions developed in four localities of Menongue Municipality (Kuando Kubango Province, Angola) to an increase in the number of malaria cases there.
Methods: parasitological screenings were carried out by means of rapid tests and screenings in sites of reproduction and captures of adult mosquitoes vectors of malaria in four localities of Menongue Municipality, in January 2014.
Results: 49.3% of the screened population was found to be positive to malaria, specifically by Plasmodium falciparum. The age groups with higher positivity were at one to four and five to fourteen years. In the biggest group of fourteen years, positivity was higher in the female sex. Relative larval densities for Anopheles sp. found were relatively high, while adults were gathered in 40% of the sampled houses.
Conclusions: positivity to malaria was present in all the age groups, a fact that corroborates the lack of population immunity characteristic of an area of unstable (mesoendemic) malaria. This aspect, together with the presence of the disease vectors, permits us to affirm, despite the study limitations, the occurrence of an epidemic in the screened areas in the moment of the sampling.
