A cpl of other problems with this article:
It mentions the fact that both SARS and MERS were responsible for more deaths so far (that is if for some reason we decide to accept his claim of 500 deaths for the Novel-c virus).
What he isn't taking into account is that the SARS epidemic lasted 9 months, and the 800 deaths attributed to that strain included all the casualties of the epidemic along with any fatalities since it appeared in 2002, 18 years ago.
MERS has been around since 2012, and the 858 deaths are a summary of the last 8 years.
So what we really have here:
MERS 858 deaths over the course of 8 years.
SARS 800 deaths over the course of 18 years.
Novel coronavirus 500 over the course of something like 6 weeks.
And that's if we accept the authors count, which again seems unfounded. Especially when compared to stats from more reliable sources, which put the count over 1300 so far.
The author also points out that the novel virus is no more contagious than the measles.
Thing is, we have a vaccine for the measles, and even so:
"In 2011, the WHO estimated that 158,000 deaths were caused by measles. This is down from 630,000 deaths in 1990.
[78] As of 2018, measles remains a leading cause of vaccine-preventable deaths in the world.
[15][79] In developed countries the mortality rate is lower, for example in England and Wales from 2007-2017 death occurred between two and three cases out of 10,000.
[80] "
Measles - Wikipedia
The measles has between a .1 and .2 mortality rate, compared with novel's 2+%, 10 to 20 times as high.
All in all IMO the article looks like an OP-ed by someone who didn't bother checking his facts very closely, or thinking the whole thing through very well.
