Seasonal (traditional) flu generally has a low mortality rate of 1% or below (in the USA typically around 0.1%). This has caused so far this year, 32,000,000 infections (individual infections, not individual people infected), resulting in 18,000 deaths[2]. Were these Coronavirus infections, deaths would be around 300,000 at 1%, or 1,280,000 at 4%."Globally, about 3.4% of reported #COVID19 cases have died. By comparison, seasonal flu generally kills far fewer than 1% of those infected"-@DrTedros #coronavirus— World Health Organization (WHO) (@WHO) March 3, 2020
Alternatively, according to a study from Harvard, an estimated 40-70% of the global population may be infected by Coronavirus. If this projection is accurate deaths from COVID-19 will range between 30,000,000 and 200,000,000 individuals.
