OBJECTIVE: To evaluate the epidemiological profile and the temporal distribution of
leptospirosis cases in Belém of Pará in a period between 2010 to 2019. METHODS: This is an
ecological, quantitative and descriptive study. Data were collected regarding confirmed cases
of leptospirosis notified in Belém-Pa between 2010 and 2019, available in the Notifiable
Diseases Information System (SINAN). The Microsoft Office Excel 2019 and BioEstat 5.3
programs were used to perform the quantitative descriptive statistical analyzes and to
structure them in spreadsheets, charts and graphs. Subsequently, the data was interpreted
according to the objectives. RESULTS: Leptospirosis had a high incidence in Belém (4.61
cases/100 thousand inhab.), Considerably higher than the state (1.49 cases/100 thousand
inhab.) And the national (1.80 cases/100 thousand inhab.). As for temporality, it was
endemic, due to the uninterrupted annual appearance of cases, and seasonal, due to the
periodic increase of cases in rainy periods, especially between January and May. Regarding
demographic characteristics, the majority of cases were brown, male, aged between 20 and
39 years old and came from the city of Belém. Regarding the infection environment, the
household was the predominant one. Lastly, a considerable mortality rate from leptospirosis
(16%) was noted. CONCLUSION: This study demonstrated that leptospirosis is still a notable
public health problem in the city of Belém do Pará. The results suggest the need for
improvement in basic sanitation services, such as the adequate collection of garbage and the
improvement of the drainage system of the city; in addition, implementation of education
campaigns aimed at prevention.
