Further matches have been postponed while others appear unable to go ahead due to increased travel restrictions between affected countries.
Governing bodies are also taking steps to reduce the spread of COVID-19 by cancelling planned meetings, while others are calling for further changes to the calendar.
Here are some of the latest events to be impacted.
Football's governing body has decided to cancel the next FIFA Congress in Addis Ababa on June 5. It has also pushed back the coming FIFA Council meeting in Zurich, due to be on March 20, until June or July. Attendees may be required to join via a video link.
In France, the Coupe de la Ligue final on April 4 between Paris Saint-Germain and Lyon has been postponed. The Ligue de Football Professionnel (LFP) said a new date would be announced in due course. It means the PSG-Metz and Lyon-Nimes Ligue 1 matches will be moved to the weekend of April 4-5 but be held behind closed doors. PSG will have Kylian Mbappe available against Borussia Dortmund on Wednesday, though: the striker is in the squad after overcoming illness, with L'Equipe among those to report he had tested negative for coronavirus.
Germany has seen the first confirmed instance of a footballer contracting coronavirus. Hannover defender Timo Hubers has tested positive but been praised by the club for his "absolutely exemplary" behaviour, as he immediately self-isolated before coming into contact with the rest of the squad.
Bundesliga champions Bayern Munich will face Union Berlin on Saturday behind closed doors, and the latter's derby with Hertha Berlin on March 21 will take place under the same circumstances. Borussia Monchengladbach have urged fans not to gather outside the stadium ahead of Wednesday's match with Cologne.
FIFPro, the footballers' union, has urged governing bodies across the world "to respect the wishes of players to take short-term precautionary measures including suspending training or competitions". Steps are certainly being taken in Spain, where the Royal Spanish Football Federation (RFEF) has recommended football at all levels beneath the top two professional leagues to be called off for two weeks. The RFEF will reportedly meet with league officials to discuss similar proposals for LaLiga and the Segunda Division.
Meanwhile, Roma's match with Sevilla in the Europa League last 16 on Thursday is off after the Italian club confirmed they had not been given permission by the government to fly to Andalusia. Getafe had already refused to travel for their game with Inter in Italy.
The big news in Englandwas that Manchester City versus Arsenal was called off as a precaution after the Gunners came into contact with Nottingham Forest owner Evangelos Marinakis, who announced on Tuesday that he had caught the disease. In general, though, the UKhas not been following the same stringent protocols as some other European nations and that is continuing for now. Arsenal's match with Brighton and Hove Albion on Saturday has not been called off, while England's planned friendlies at Wembley this month against Italy and Denmark are, at present, going ahead. Forest have also confirmed all players and staff have tested negative for coronavirus.
In Scotland, Rangers boss Steven Gerrard says the domestic season must be completed, even if behind closed doors, "because people have earned the opportunity to get to the stage where everyone is at". League chief executive Neil Doncaster claimed last week that completing the Premiership season could become "very difficult".
The England and Wales Cricket Board has told supporters "to maintain good levels of hygiene" during England's tour of Sri Lanka. As a precaution, players and staff have been told to avoid casual interaction with fans, such as selfies and autographs.
In Bangladesh, the World XI v Asia XI matches that would have marked the birthday celebrations of Sheikh Mujibur Rahman have been postponed, while the Indian Open has been called off following a consultation between the Indian Golf Union, the European Tour, the Asian Tour and tournament sponsors.
MotoGP has also announced that the ArgentinaGrand Prix has been moved to November. The opening race of the season in Qatar and the Grand Prix of the Americas have already been rescheduled.
The game was due to take place at the Stade de France on April 4.
France's Ligue de Football Professionnel (LFP), which held talks with both clubs and the French Football Federation (FFF) on Wednesday, has not yet suggested a new date.
The competition is due to be scrapped after this season in order to reduce player workload.
As a result of the final being postponed, the PSG-Metz and Lyon-Nimes league matches will be staged over the weekend of April 4-5, behind closed doors.
The LFP had already confirmed on Tuesday that all Ligue 1 and Ligue 2 matches are to be held without fans present until at least April 15 as part of nationwide measures aimed at curbing the spread of COVID-19.
PSG are due to face Borussia Dortmund in the Champions League last-16 second leg at Parc des Princes on Wednesday, which will also be behind closed doors.
There have been 1,748 confirmed cases of the virus in France, with 33 people killed.
The Ligue 1 season was abandoned in April, so many supporters will have to wait until the 2020-21 campaign begins to see live football again.
But the end of France's health state of emergency from July 11 will see restrictions eased, with stadiums and horse-racing tracks to be reopened to the public, initially at a reduced capacity.
The news came in a statement from the government that specified: "As with performance halls, activities involving more than 1,500 people must be declared, so that the necessary precautions can be guaranteed.
"The maximum capacity of 5,000 people for major events, stadiums and performance halls is in principle in force until September 1. A new review of the national epidemiological situation will be carried out in mid-July to decide whether a relaxation is possible for the second part of August."
The French Football Federation (FFF) is hoping the 5,000 figure may be relaxed sooner than September, with reports this week saying the Coupe de France final, postponed from April, is pencilled in for July 24.
Paris Saint-Germain are due to face Saint-Etienne at the Stade de France, which can seat over 80,000 spectators.
FFF president Noel Le Graet called the government ruling "an important step in the organisation of upcoming games".
"These new provisions allow us to envisage opening even more widely for spectators regarding the men's Coupe de France final at the end of July, the Coupe de la Ligue final, the semi-finals and final of the women's Coupe de France at the start of August, as well as the return of Ligue 1 and Ligue 2 at the end of August," he said in a statement on the FFF website.
"The FFF executive committee will meet on Monday June 22 to consider the new measures and the upcoming calendar."
The France international sprained his ankle in last week's Coupe de France final victory over Saint-Etienne and scans on Monday revealed he will miss around three weeks.
PSG face Atalanta in a one-legged tie in Lisbon on August 12 and Tuchel, while not completely ruling Mbappe out, concedes it is almost certain he will be without the striker.
"We still have hope and every day counts to achieve a miracle," Tuchel said at a news conference ahead of PSG's Coupe de la Ligue final with Lyon on Friday.
"But tomorrow we will be without him and his absence will have an influence on us. I hope that a solution can be found."
Thilo Kehrer and Colin Dagba are expected to miss out against Lyon, while Juan Bernat remains doubtful, but Marco Verratti will be hopeful of earning a recall to the side.
Tuchel left Verratti on the bench for 75 minutes last week, instead preferring Leandro Paredes alongside Idrissa Gueye, and has hinted he may again elect for a 4-4-2 on Friday
"It was a super complicated decision to leave Marco on the bench, but I felt I deserved to let Idrissa and Paredes play together after the Borussia Dortmund result," he said.
"If we do keep our 4-4-2, we can do that with Eric Maxim Choupo-Moting, Angel Di Maria or Pablo Sarabia.
"We can make the decision tomorrow. I want to wait until after the final training session."
PSG have won the Coupe de la Ligue a record eight times, including five seasons in a row before last year, and are strong favourites to overcome Ligue 1 rivals Lyon.
But Tuchel says it would be wrong to write off Friday's opponents, who lead Juventus 1-0 in their Champions League last-16 tie, and look ahead to the clash with Atalanta.
"Tomorrow will be a huge challenge against a Champions League-level opponent," he said.
"We won a complicated match against Saint-Etienne and this is now another step up against a side on course to eliminate Juventus.
"We cannot prepare to face Atalanta yet. I don't know another team that plays like them. All we can do is work on our state of mind and how our hunger to win matches.
"That will prepare us well if we get a positive result against Lyon."
