BARBOSA, Maria Helena  and  GRAZIANO, Kazuko Uchikawa. Influence of wearing time on efficacy of disposable surgical masks as microbial barrier. Braz. J. Microbiol. [online]. 2006, vol.37, n.3, pp.216-217. ISSN 1517-8382.

The present study evaluated the efficacy of disposable surgical masks as a microbial barrier with 95% of Bacteria Filtration Efficacy (BFE) according to the wearing time (1, 2, 4 and 6 hours). The masks showed a decrease in efficacy after a 4-hour wearing time.

Keywords : surgical masks; hospital infection; microbial barrier.
