Coronavirus is probably dominating global news coverage in a way that no event has since the 9/11 terrorist attacks.
About half of the articles written in the past few days by Bloomberg, the New York Times and the Washington Post cite coronavirus.
In Italy, 70 percent of the articles written by the leading news agency ANSA mention the outbreak. In Hong Kong, almost two thirds of the stories in the South China Morning Post cite coronavirus.
And these are big sample sets. Bloomberg runs 700 long-form major news articles a day, the Post runs 800 and the Times carries 500. ANSA runs 700.
On Twitter, coronavirus was mentioned in 10 percent of the 500,000 posts Bloomberg classifies as financially relevant.
