Masks the best bet to avoid SARS
May 02, 2003
SURGICAL-quality face masks, but not paper ones, offer the best protection against the SARS virus, according to a study detailed in The Lancet.
Doctors at Queen Mary Hospital in Hong Kong, one of the epicentres for the SARS scare, looked at the precautions taken by 254 colleagues who had been exposed to 11 people infected with the pneumonia-like disease.
The participants were quizzed closely as to whether they had followed recommendations to wear a mask, gloves and gown and scrupulously wash their hands when caring for SARS patients.
Of the 241 staff members who were uninfected, 69 had obeyed all four recommendations.
The 13 infected staff had omitted at least one measure, but there was a common denominator: they had not worn a surgical mask.

Effectiveness of precautions against droplets and contact in prevention of nosocomial transmission of severe acute respiratory syndrome (SARS)
W H Seto, D Tsang, R W H Yung, T Y Ching, T K Ng, M Ho, L M Ho, J S M Peiris, and Advisors of Expert SARS group of Hospital Authority* *Members listed at end of report
We did a case-control study in five Hong Kong hospitals, with 241 non-infected and 13 infected staff with documented exposures to 11 index patients with severe acute respiratory syndrome (SARS) during patient care. All participants were surveyed about use of mask, gloves, gowns, and hand-washing, as recommended under droplets and contact precautions when caring for index patients with SARS. 69 staff who reported use of all four measures were not infected, whereas all infected staff had omitted at least one measure (p=0·0224). Fewer staff who wore masks (p=0·0001), gowns (p=0·006), and washed their hands (p=0·047) became infected compared with those who didn't, but stepwise logistic regression was significant only for masks (p=0·011). Practice of droplets precaution and contact precaution is adequate in significantly reducing the risk of infection after exposures to patients with SARS. The protective role of the mask suggests that in hospitals, infection is transmitted by droplets.
