The coronavirus outbreak has forced England's Guinness Six Nations match at Italy on March 14 to be postponed.
There was the option to play the Rome encounter behind closed doors, but tournament organisers have chosen to reschedule it for later in the year, which will also be the case for the Ireland-Italy game due to be played this weekend and also postponed because of the spread of Covid-19.
In addition to this, the Women's Six Nations match between Italy and England in Padua on March 15 has been called off, following on from the previous postponements of the Italy-Scotland and Ireland-Italy games in the tournament.
The Italian government decree released on Wednesday said all sporting events in the country would not be open to the public until April 3 in an attempt to halt the spread of the virus.
Italy is the European country most affected by coronavirus, with more than 3,000 people infected – a number which includes over 100 deaths. Eleven towns in northern Italy are in lockdown.
Speaking at the FT Business for Football summit, Agnelli said: "The phase we are in with spread of Covid-19, public health is paramount and the objective of everyone is to contain the virus as much as possible.
"Our position as a club has been clear. We have to take the line of the scientific community of what should and should not be done, then it's the role of the authorities to come out with the correct pieces of law and sporting authorities must follow suit.
"We must behave responsibly. The economic effects of such responsible action should and will come second. From there on it is not for clubs to decide what should be done, our responsibility is to follow what the authorities have told us in the interest of public health."
Golf continues to be badly affected by the spread of the virus, with the MENA Tour postponing the rest of this season's tournaments until September-December.

A statement from the MENA Tour read: "Unfortunately, due to the various travel issues caused by the ongoing COVID-19 situation, the MENA Tour by Arena has decided to postpone the remainder of our 2020 season to September-December. We will post the new schedule as soon as possible."

A statement confirmed the team will not return to racing until March 20, meaning they will not participate in races at the Strade Bianche, Paris-Nice, and Tirreno-Adriatico.
General manager Alexandr Vinokurov said: "With this measurement, we have chosen to protect the health of our riders and staff and to take our responsibility for the society in not further spreading the virus.
"Of course, we would have preferred to participate in all upcoming races, but for now, it's safety first. We still have a long season ahead with many other important races. It was not an easy decision, but we have to protect the cycling family as well as our own families at home."
