Preliminary studies suggest Wuhan coronavirus is fatal mostly to east asians ethnicity. Non East Asians have very little ACE2 enzym in their lung cells which are used by the virus as an entry mechanism

I find it odd that only Singapore mentioned that Coronavirus is an unstable virus that would burn itself out in 8 months. Dare not or intentionally or unaware of this known trait?
Phua, the health economist…Phua, who was an associate professor of public health administration at the National University of Singapore during the Sars outbreak…
Phua said even though experts were still discovering certain properties of the novel coronavirus, there are common traits of coronaviruses that are already known.
For example, a coronavirus will generally burn itself out because it is an unstable virus, said Phua, adding that Sars burned itself out in eight months.
I wonder if this enzyme has anything to do with breaking down toxins in cigarette smoke. Might explain why those Asians are long lived yet smoke like chimneys.
