The Week

[Chaseman]

Last one and it should be simple!

25d Complaints in abundance when hospital not available (4) ?L?S
Looks like ILLS but can’t parse it.

[Lie-in King]

Flus(h) - in abundance, no 'h(ospital)'

[1ozzy]

Flus.
Multiple cases of influenza.
Abundance = flush
Flus(h)

[Chaseman]

Thanks LIK, bit of a Delphic one but your logic is unassailable. Who talks about flu in the plural? You wouldn’t say “there are a lot of flus around this winter”.
