Re: In Beijing, coronavirus 2019-nCoV has created a siege mentality

Dear Editor,

Following Mr. Stone's reply, I am annoyed that WHO has mentioned nothing regarding tobacco use and COVID-19.

My boss showed a China Daily press article where a paper allegedly stated that smoking protects against COVID-19 infection ( After looking at the original source, it was recent non-peer-reviewed manuscript where the authors show that smoking seems like it had no effect regarding deaths among COVID19 infected patients. In my view, this is nonsense! The manuscript deserves to be peer-reviewed: I suspect that a mistake in the modelling led to that crazy result! The paper does not aim to assess how smoking increases or not COVID infectivity because it was a COVID infected patients cohort.
