Malaria is an infectious parasitic disease caused by a protozoan of the genus Plasmodium, transmitted by the bite of the female mosquito of the genus Anopheles, annually affecting about 300 to 500 million people distributed in 100 countries with poor sanitary conditions. This study aimed to characterize the epidemiological profile of positive reports of malaria in the municipality of Mazagão, Amapá, in the period 2010- 2019. the Epidemiological Surveillance Information System (SIVEP–MALARIA), which integrates the automated information system of the Health Surveillance Secretariat (SVS) of the Ministry of Health. 18,380 positive cases of malaria were reported, and the region with the highest number of malaria notifications was the Maracá region, 4,875 (26.52%), and even with an expressive number of cases, it does not have a high parasite rate; then the Vila Nova region which, even being in second place in the number of positive cases with 4,708 cases (25.61%) has a very high IPA. Regarding the etiological agent, there was a prevalence of Plasmodium vivax (84.78%; n=15,584) over Plasmodium falciparum (14.48%; n=2,662). Notifications involving Plasmodium falciparum are relatively high in the Maracá, Vila Nova and Rio Preto regions. Based on the number of positive notifications and the IPA of each region of the municipality of Mazagão, the Vila Nova region offers a greater epidemiological risk in the transmission of malaria, with emphasis on Vila Nova, Tapioca, Pancada I, Curumuri I and Santa Fé communities due to their higher number of positive notifications.
