| Sumario: | Hantaviruses are zoonoses that cause serious human diseases in the Americas such as hantavirus pulmonary syndrome (HPS). In Brazil HPS is a notifiable disease to health services due to its high lethality and incipient knowledge of its epidemiology. The present study describes the epidemiology of HPS in Brazil for the period 2007-2012. We conducted a descriptive study of the records of the National Notifiable Diseases System, analyzed the reporting forms and research, and the data wereevaluated for completeness of information, opportunity and profile of registered cases. The results are presented as raw numbers, measures of central tendency and proportion and analyses developed using Excel 2010 software, and 32 Tabwin terraView. In the study period 8,456 cases of HPS were reported, with confirmation of 9% (756/8,456), ideally by laboratory testing 91.1% (689/756). The average coefficient of lethality for the period was 38.2%, whilst the highest incidences of the disease were in the states of Mato Grosso, Santa Catarina and the Federal District and the greatest lethalities were in Amazonas, Mato Grosso and São Paulo. Regarding seasonality, cases were observed in all months of the year. Deaths were more frequent in males 72.3% (209/289) and high mortality was observed in women 42.3% (80/189). The cases were mainly people who conducted activities relatedto agriculture 18.8% (90/478) who were exposed to the rodent environment, 36.9% (279/756). Most of the patients 90.3% (683/756) required hospitalization and the average time expressed in number of days between the variable onset of symptoms and hospitalization, cure or death variables, were respectively (5, 11, 18). The data presented in this study highlight the necessity to focus technical skills on the recognition of the circulation of the agent, the opportunity for diagnosis and treatment and quality of information and priority factors for the strengthening of epidemiological surveillance programs of hantavirus. |
