I think it could be the end of the season, how are clubs going to start up again in April if the disease is still spreading, just taking the football side in the equation how many players or their families going to be affected, ground and stadium staff to run the clubs, this is only the first step before a bigger shutdown.
I agree, it's certainly going to be difficult to finish this season, and decide who gets promoted, relegated, title winners etc, and how they can make these decisions without massively effecting next season is beyond me, but it is what it is.
From a health and safety point of view, the EFL can't allow events under their stewardship to go ahead, when hundreds of thousands of people all over the country will be flooding stadiums, public transport, carpools, pubs, restaurants etc risking a huge increase in widespread infection.
There will always be cocky smart arses who think they know best, and will say cancelling sporting events is an overreaction, but I heard someone (Rory Mcilroy I think?!?) quoted on sky sports today as saying: "Today's overreaction, might be tomorrow's under reaction" and it's very true, this is a serious situation, and we can't be too careful.
It would be a bloody awful way for what has been an amazing season to end though
