I'm not suggesting "lockdowns" here. I'm advocating for indoor air quality regulation: maximum CO2, minimum fresh air ACH, deploying upper room UVGI ~everywhere. Universal masking (N95+) in healthcare settings.

Acute and specific things we could do to mitigate H5N1 right now, in particular, are deploying the vaccine we have to all poultry and dairy workers to reduce animal to human crossovers.

I was responding to your flippant suggestion to "Quarantine, voluntary or otherwise, the elderly and at-risk then."

Which I pointed out is not possible, because those people depend on many other healthy people to care for them. Either those people also need to join the "at risk" bubble (not feasible since they have jobs, school etc) or you don't really have the at risk population isolated as you suggest.

If you don't understand this then you have no idea how care networks function, with duties spread across facility staff, families, volunteers, visiting caregivers etc.

Suggesting you cut off one or more legs of those support networks isn't practical or humane. It would mean people without adequate support for basic needs like feeding, toileting & bathing, leaving aside mental/physical exercise and socialization.
