We assigned one point to full articles and to front-page articles or headlines and half a point to short arti- cles. We also reviewed all national newspapers for articles published before the travel advisory (March 12–15)(Figure). Before the travel advisory, no arti- cles were published in the five news- papers, whereas on March 14, one article was published in a smaller newspaper (“Osservatore Romano,” the Vatican newspaper). On March 16 (the day after the advisory), six arti- cles appeared in the five newspapers; through May 31, a total of 750 articles were published. The proportion of Figure.
