"The virus is highly infectious, potentially nearly twice as infectious as the flu. It might be far higher, there isn’t anywhere near enough data yet.
Infected people could spread the disease for up to two weeks before showing symptoms.
Some people don’t show any symptoms at all and could infect an enormous number of people.
In The Atlantic, Marc Lipsitch, a leading epidemiologist at Harvard reported that “that within the coming year, some 40 to 70 percent of people around the world will be infected with the virus that causes COVID-19”. This was last week and while ridiculed at the time, his assumptions are now the generally accepted position among epidemiologists."
In my somewhat amateur opinion the highly infectious nature of the virus suggests that it was "weaponised" in precisely the way suggested by Prof.Doyle (and others), the "escape" from Wuhan and the timescale for the spread all indicate an extremely pernicious infection. To say "don't worry about the death rate" when it is generally accepted to be over 1% smacks of a rather eugenicist approach esp. if you are part of the population considered to be vulnerable. Let's remember that doctors and nurses have already died in Wuhan, presumably they were all reasonably fit and strong individuals under the age of retirement so the "don't worry the other guy will get it" blandishments don't wash in any case..
