You have an excellent point on changing policy and changing it to what?
I worked in Toronto, Canada, in 2003, and 44 Canadians died of SARS that year. That is horrible, and there were 800 deaths globally. However, also in Canada, 2,000 people die in car accidents annually, and 3,500 die from the seasonal flu. I fully understand those risks, and yet I still drive my car and will go out in public without a mask.
The media is sharing the information and humans focus on the negative. But I have to ask myself if I just take regular hand washing, sanitizing surfaces and being cautious the odds are overwhelming that we will be fine.
