EPIZOOTIC DYNAMICS AND STRUCTURAL DISPARITY IN THE LABORATORY DIAGNOSIS OF SPOROTRICHOSIS (2016-2026): IMPLICATIONS FOR INTEGRATED PUBLIC POLICY FORMULATION IN RIO GRANDE DO NORTE

Le résumé fourni par la source

Sporotrichosis, primarily caused by Sporothrix brasiliensis, represents a severe public health challenge. In Rio Grande do Norte (RN), Brazil, its epidemic expansion is worsened by fragmented epidemiological data. This descriptive ecological study analyzed the epidemiological profile and diagnostic accuracy of human and animal sporotrichosis in RN from 2016 to 2026, using secondary data from CIES-RN, SINAN, and LACEN-RN. The analysis revealed a significant diagnostic discrepancy between species. Out of 981 suspected human cases, 606 were confirmed: 79.9% (n=485) through clinical-epidemiological criteria and only 20.1% (n=121) via fungal isolation. Conversely, among 1,790 confirmed animal cases, 63.2% (n=1,132) ha a definitive laboratory diagnosis, while 36.8% (n=658) were confirmed by clinical-epidemiological linkage. The low microbiological confirmation rate in humans (20.1%), compared to an animal diagnostic coverage three times higher, highlights structural flaws in health surveillance. Adopting integrated diagnostic and management protocols under the One Health approach is imperative to mitigate the agent's spread and improve the state's epidemiological response.
