I recently stumbled upon this photo I made at the Toronto Pearson International Airport (YYZ) in 2003 warning passengers about the severe acute respiratory syndrome (SARS) epidemic.
According to Wikipedia, over “8,000 people from 29 different countries and territories were infected, and at least 774 died worldwide. The major part of the outbreak lasted about 8 months, since the World Health Organization declared SARS contained on 5 July 2003. However, several SARS cases were reported until May 2004.”
Wikipedia adds that COVID-19 is closely related to SARS. In retrospect, the impact in 2003 was minor — although it did not feel like that at the time.
