Method: Cross-sectional study with 29 health professionals from a teaching hospital, from March to April 2012, through the collection swab of the the nasal mucosa. Microbiological tests were performed at the University of Santa Cruz do Sul. The data were analyzed descriptively and it was given an α risk <5% (p<0.05) and 95% confidence interval.
