The Tuscany-based club’s players and officials have been quarantined for 15 days as a precaution after the first signs of the disease was discovered following a championship game at Alessandria last week.
Pianese’s league games within the 15-day period have all been called off.
As at Saturday, over 400 cases of the Coronavirus disease have been reported in Italy, making it the hardest hit country in Europe. Twelve deaths have been recorded in the country so far.
Five games in the Italian top flight including Sunday’s Derby d’Italia between Juventus and Inter Milan have been called off and rescheduled for May 13.
"At the moment those infected are four, three players and a team official," a spokesman for Pianese said.
"The first is a young player who had started to experience a slight rise in temperature and headache last Saturday, when the team was away to Alessandria to play a championship game.
"The second player is in self-isolation at his home, while not showing any symptoms, as well as the third player who is slightly feverish.
"The fourth person tested positive for the swab is a club official who this morning, after spending the night in a feverish state, was transported by ambulance to the hospital in Siena.
"Currently, all the players, the technical staff and the managers present during the trip last weekend are in a 15-day quarantine."
