Brazil and Rio de Janeiro on a collision course with football's fight against coronavirus

Those two teams were ordered to play on Sunday, and took the field under protest. Botafogo's coach, the vastly experienced and highly respected Paulo Autuori, wanted to resign earlier in the week to avoid taking part, but was talked into staying. Fluminense forced a change of stadium after making it clear that they would not play in the Maracana, alongside the hospital. Three players of Volta Redonda, the opposing team, tested positive for the virus on the day of the match.

And the conflict is not likely to go away. The matches so far have been, of course, behind closed doors. But the local authorities plan to allow stadiums to be full to one-third of their capacity from July 10, and two-thirds from the start of August. The rest of the continent, still at the planning stage, seems resigned to playing behind closed doors for the foreseeable future.

The problem is that it is not clear that the virus has passed its peak. Over the past few weeks, a number of Brazilian cities have reopened their economies. Some are already backtracking as the number of coronavirus cases increases. In a scenario where it would be advisable to err on the side of caution, Rio is taking the opposite road.

In part this is an attempt to force the kick off of the national Brazilian Championship, where early August has been penciled in as a start date.

CONMEBOL, the South American Confederation, might be happy with this news, but there are also causes for concern.

With clubs all around the continent desperate for income, there is pressure for a quick resumption of the Copa Libertadores, South America's Champions League. Brazil is a huge part of the competition, supplying seven of the 32 teams. The Libertadores, then, cannot restart until Brazilian football is back. The position of CONMEBOL is that the action can only resume once all 10 of the continent's footballing nations have opened their borders, but it is clearly more important to have Brazil up and running than, say, Venezuela, which has just two participants.

But Brazil returning under these conditions -- well before coronavirus is brought under control -- is also a problem. For all that the teams might be willing to travel to play their matches, governments might not be so keen. Paraguay has worked extremely hard to reduce the impact of the virus. Would its health authorities be happy to see Olimpia in action home and away against Santos, or to see Palmeiras visit Guarani?

In these cases, the two Paraguayan sides are up against teams from the state of Sao Paulo, the worst-affected city in South America.

Unless there is a dramatic improvement in coronavirus control in Brazil, the Paraguayan government would surely be justified in viewing these games as an unnecessary risk.

And there is another headache on the horizon. The current plan is to kick off the 2022 World Cup qualifiers in early September. South America plays doubleheaders, with all the teams in action both home and away over the course of a few days. This means there is plenty of travelling for the Europe-based stars. There is not only the trip over the Atlantic, but also a potentially lengthy journey inside South America.

This second part is particularly worrying. Would a European club feel happy releasing a star player for matches against Brazil, in Brazil or travelling through Brazil? Again, unless there is a dramatic improvement, the answer must surely be an emphatic "No."

And from Lionel Messi to Neymar, passing through Arturo Vidal, Luis Suarez and James Rodriguez, the big names in South America's World Cup qualifiers are almost all in Europe.

Brazil, and Rio football, is choosing to be an outlier in the way it deals with controlling the coronavirus. But the game takes place in a global context. Brazil can only get so far on its own.
