Resumo
The hantavirus is an emerging zoonosis, considered a public health problem due to its high mortality and hospitalization. Transmission occurs by exposure to excreta of infected wild rodents, primarily via aerosol. The aim of this study is to evaluate the hantavirus monitoring system in the State of Goiás, in the period 2007 to 2012. This is an observational, descriptive and cross-sectional study in which the clinical and epidemiological features of hantavirus were analyzed and their attributes according to models proposed by the Updated Guidelines for Evaluating Public Health Surveillance Systems and Framework for Evaluating Public Health Surveillance Systems for Early Detection of outbreaks of the Center for Disease Control and Prevention and the Department of Health Surveillance. 63 cases were confirmed in the analyzed period. The disease has the highest number of confirmed cases in absolute numbers in 2009, with higher positivity of the relationship notification / confirmation in 2008. The municipalities of greater nudges Annapolis, Goiânia and Jataí. The hantavirus predominantly hit men, race / brown color, living in an urban area with high school education, being related to agricultural occupations and largest exhibitions in environments cleaning situations and in direct contact or with traces of a mouse . Most cases were reported in the first four days of the onset of symptoms, with signs of fever, dyspnea, and myalgia. He has performed many laboratory tests and imaging. However, it was demonstrated deficit of completeness in these fields in the reporting forms. The most notable changes are nonspecific hematocrit> 45% and thrombocytopenia, and on imaging, diffuse pulmonary infiltrates. More than 85% of the cases were confirmed by laboratory testing (IgM) and clinical form of hantavirus cardiopulmonary syndrome. High hospitalization rate, especially on the first day of care, was quite considerable and demand for organ support. The municipalities with the highest indication of Infection Likely Place are Annapolis and Jataí, in rural areas and work environment, with closure in time in just over 60% of cases. Although theoretically the system is useful in practice, low valuation is observed quantitative attributes (sensitivity, predictive value of positive, opportunity, stability) and qualitative (simplicity, flexibility and acceptability - in the question data quality assessment is average the bad). As for the management indicators was observed weaknesses in their use. From the analysis of the hantavirus surveillance system in Goias, 2007-20012, it was concluded that the current system is fragile. It is suggested a number of recommendations in order to give more useful reducing the socioeconomic impact of the disease through the continuous improvement of services provided by various levels and professional sectors, as well as the construction of an education service in health and prevention mainly for environmental management measures that prevent / reduce the risk of the presence of possible rodents infected with the human environment.
