Household transmission of SARS: Lessons learned

In the 2003 outbreak of severe acute respiratory syndrome (SARS) in Toronto, Ontario, about 20% of cases resulted from household transmission (spread of the infection within a household). Wilson-Clark and colleagues studied the characteristics of these household transmissions and report on risk factors th...
