Seems to have completely vanished again around where I am - you wouldn't even know it was even a thing except for the odd signs, etc. still around.
I do dread this coming winter though - I think the level of prevalence generally in the population is potentially going to enable a very rapid spike once the season comes when these kind of diseases tend to start going around proper.
We used to have much more planning for it - but despite at the time recent reports highlighting the risks of it and being one of the biggest potential likely threats most of the old planning was retired without replacement.
While more for dealing with stuff like potential use of various chemical or biological agents in a terrorist attack type scenario than a virus like this for instance the lab I worked in as an assistant for awhile had emergency procedures to rapidly repurpose as a biosafety level lab (can't remember the grade) and there was a plan in place to establish a direct transit corridor with the local district hospital (opening up access via disused railway cuttings, etc.) avoiding road bottlenecks - then around 10 years ago that was all shelved without any replacement.
