Authorities in northern Italy on Friday ordered the closure of schools, bars and other public spaces in 10 towns following a flurry of new coronavirus cases.
Five doctors and 10 other people tested positive for the virus in Lombardy, after apparently frequenting the same bar and group of friends, with two other cases in Veneto, authorities said at a press conference.
Over 50,000 people have been asked to stay at home in the areas concerned, while all public activities such as carnival celebrations, church masses and sporting events have been banned for up to a week.
Italian Prime Minister Giuseppe Conte said "everything is under control", and stressed the government was maintaining "an extremely high level of precaution".
Streets in the towns were deserted, with only a few people seen abroad, and signs showing public spaces closed.
In Casalpusterlengo, a large electronic message board outside the town hall read "Coronavirus: the population is invited to remain indoors as a precaution".
The first town to be shuttered was Codogno, with a population of 15,000, where three people tested positive for the virus, including a 38-year old man and his wife, who is eight months pregnant.
Three others there have tested positive to a first novel coronavirus test and are awaiting their definitive results.
Codogno mayor Francesco Passerini said the news of the cases "has sparked alarm" throughout the town south of Milan.
The 38-year old, who works for Unilever in Lodi, was in a serious condition in intensive care.
- 'Extremely worried' -
He had dined earlier this month with a man who had visited China in January, and had later shown flu-like symptoms, but has since tested negative for the virus, Italian media said.
A football friend of his, the son of a bar owner in Codogno, has also tested positive, along with three regulars at the bar.
The three, all of whom are retired, live in the small town of Castiglione d'Adda. The mayor there said the locals were "extremely worried" about the spread of the deadly disease.
