DISPERSION AND CONTROL OF SARS VIRUS AEROSOLS

The severe acute respiratory syndrome (SARS) epidemics in Hong Kong and elsewhere be 2002 and June 2003 have left us an unanswered question – were the SARS virus transmission airborne in some of the super spreading events? Before the epidemiological answer to this question becomes available, it is important that we consider the possibility of airborne transmission when dealing with environmental control measures such as air conditioning and ventilation design in SARS wards wards. Epidemiological studies on the Amoy Garden outbreak and the 8A ward outbreak in the Prince of Wales Hospital have shown that the possibility of airborne transmission cannot be ruled out at the time of writing this paper(i.e August 2003).
