Regular testing & all games behind closed doors will lower risks. People are going to get the virus & people are going to die no matter what we do. The virus isn’t going away, a vaccine will take years. The world needs to start again, only a tiny minority of people die so sadly we need to accept some collateral damage.
The problem is the elderly should be isolated somehow to reduce risks of having close contacts with the young. And the young need to self-adjust and also reduce their intensity of contacts to the elderly. Together, the elderly will be provide better from the virus with less infections. When the world has globally or nationally community immunity, things will be better for all. I would like to use the "community immunity" rather than the "herd immunity" that was born for too long and considered people like animals.
The young, basically don't like isolation or quarantine so it will be good for them to go outside, works, enjoy their lifes and somewhat help the elderly with better community immunity.
Anyway, a new small info is now official if the season will start (and we are going in this direction) teams cause the big number of games in a short amount of time and the hot incoming (in June we are over 30 in Italy even 35) teams will can up to 5 substitutions for the game.
It is a good news that Serie A has still been on its direction to resume.
