Lazio kept their bid for a first Serie A title in 20 years on track as they stayed one point behind leaders Juventus with a 3-2 win at Genoa, but four Serie A matches were postponed amid growing coronavirus fears in northern Italy.
Reigning champions Juve had edged out bottom club SPAL 2-1 on Saturday, but Lazio responded to keep the pressure on, extending their unbeaten away run in the league to 20 games on Sunday.
Third-placed Inter Milan, who are six points behind Juve, saw their game on Sunday at the San Siro against the other Genoese club, Sampdoria, postponed, with Thursday's Europa League match against Bulgarian club Ludogorets at risk, along with next weekend's league clash with Juventus in Turin.
Three other top-flight matches were also pushed back: between Torino and Parma, Atalanta versus Sassuolo and Hellas Verona against Cagliari.
Prime Minister Giuseppe Conte announced that all sporting events in two northern regions would be suspended on Sunday.
Strong measures are being taken in Italy with over 152 confirmed cases of coronavirus in an outbreak that has claimed three lives in the country.
"I think it's right to take the necessary precautions," said Lazio coach Simone Inzaghi.
"Do a lot of prevention, try to defeat and understand the problem by stopping the championship, because we shouldn't underestimate what is happening."
"We are there in the chase and we will try to fight."

"I accept the critism," said Fonseca. "If things are not going good the coach takes the blame, so in those moments I wasn't expecting flowers."
"These two wins will give us a boost going into the next few games."
