Abstract
Objective: To provide information on the epidemiological situation of leptospirosis in the city of Belém – Pará, from 2010 to 2019. Methods: A descriptive-analytical population-based study of notified and confirmed cases of leptospirosis in the city of Belém was carried out. The data used were collected from the Information System for Notifiable Diseases (SINANNET) belonging to DataSUS. The incidence of leptospirosis cases over the years was analyzed. Results: 644 cases of leptospirosis were confirmed. The greatest volume of cases was registered in the months of January to May, coinciding with the period of greater rainfall and high tides. The highest percentage of infection occurred in males, with 80.59%. In urban areas a total of 76.08% cases. Of the cases confirmed by evolution, 76.40% were cured, 16% died. There was an increase in incidence, with the correlation coefficient (R2) equal to 0.5574. Conclusion: The occurrence of cases is associated with periods of high rainfall, flooding and lack of basic sanitation in the capital, conditions that are favorable for the bacteria to spread.
