Avaliação da presença de Mycobacterium tuberculosis, vírus influenza e vírus sincicial respiratório em indivíduos infectados por SARSCoV-2 na região sul do Rio Grande do Sul

Abstract

COVID-19 is the disease caused by the SARS-CoV-2 virus, which can progress to severe acute respiratory syndrome (SARS). In 2019, the virus spread rapidly, causing a pandemic. Due to the lack of adequate clinical management with the disease, several coinfections by other pathogens, mainly respiratory, have been reported, among them the bacterium Mycobacterium tuberculosis, respiratory syncytial virus, and influenza. The symptoms caused by these microorganisms, both causes of flu syndrome, are similar to COVID-19 and present a major risk factor for infected individuals. The aim of this study was to detect the presence of M. tuberculosis DNA, influenza viruses RNA and respiratory syncytial viruses RNA. The analyses were performed from samples of COVID-19 positive patients collected and processed in the M&S Clinical Analysis laboratory. In the present study, M. tuberculosis DNA, influenza virus RNA, or respiratory syncytial virus RNA were not detected in the analyzed samples.
