This is a preliminary epidemiological study of the first 5,830 confirmed cases of COVID-19 in Italy, which aims precisely to trace the course followed by this virus. For this virus, it is the first study of its kind outside of Asia. It was posted on March 20 on the pre-publication server ArXiv.
When the first Italian case was detected on February 20, “the epidemic had already spread to most municipalities in southern Lombardy,” the researchers conclude.
It should be noted that it is also January 1, by an article in the South China Morning Post, that the world became aware that an epidemic was gaining ground in the Chinese province of Hubei. On January 23, his metropolis, Wuhan, was literally quarantined, soon followed by the entire region.
