Malaria is a parasitic disease with severe morbidity and mortality. It is caused by
species of the protozoan of the genus Plasmodium and is transmitted to humans
through the bite of the Anopheles mosquito, when an infected female performs a blood
meal on an individual to feed. In Brazil, malaria is a public health problem, especially in
the Amazon region with the vast majority of registered cases. Coari is a Brazilian
municipality in the interior of the state of Amazonas, considered endemic for malaria.
Malaria is a notifiable disease in Brazil. Notification consists of completing a form for
the Epidemiological Surveillance Information System - Malaria Case Notification
(SIVEP – Malaria). The objective of this work was to carry out a survey of cases of
malaria in the municipality of Coari - AM notified during the years 2018 to 2021.
evaluated data related to the date of notification; infecting Plasmodium species, as well
as cases of co-infection by two or more Plasmodium species; gender and age group of
those infected; total number of positive cases and likely place of infection and place of
residence (urban, rural, indigenous area and the Urucu-Coari-Manaus gas pipeline
camp). It was observed that the predominant infecting species in the studied population
was Plasmodium vivax. As for seasonality, the highest peaks of positive cases occur
in the month of September. As for sex and age group, there was a predominance of
cases in young male adults and as for the site of infection, there was a higher
occurrence of positive cases in the rural area. The importance of this work is to fill the
current lack of scientific data related to the main infecting species and a brief profile of
infected patients in the municipality of Coari, thus contributing to the recording and
publication of these data that can be used in the future to improve public policies and
better enlightenment of the local population, since data from the SIVEP – Malaria
system are not in the public domain.
