As far as I'm aware (and you can correct me if I'm wrong), in 1957 the Asian Flu killed around 14,000 in the UK. The first case was reported in June and the peak wasn't hit until mid-October, when 600 deaths in a week were recorded. (Source: British Journal of General Practice)
Doesn't that suggest that Covid-19 is already significantly more of a risk than Asian Flu was?
