Yes, so far I'm healthy, thank you.
"Warmest appropriate setting" doesn't really say anything.
Follow the laundering instructions on the garment's tag. As has been discussed frequently on AW, those instruction frequently fail to reflect the physical nature of the garment itself. Eg. a black shirt with a tag warning not to wash it with dark colours.
A few years ago I once stayed with an elderly relative to give the caretaker a much needed long weekend away. The caretaker apologized for the state of the 'clean' laundry, saying "I followed the instructions and the stains just don't wash out." Having known the caretaker most of my life, blindly following the tag was a clear indication a break was needed.
Solid white mattress pads. 100% cotton. No elastics, fasteners, etc. The laundry instructions? "Machine wash warm. No bleach. Tumble dry low." Naturally I cranked the water heater, washed it in hot and used a thoroughly indecent quantity of Persil and Clorox. This was followed with several extra rinses. The result was hardly a surprise: Gleaming white mattress pads. Other items were treated similarly.
When the caretaker came back, the result was shock and awe. Although my wording was much more polite, the gist of my response was, "Solid white, 100% cotton, no plastic involved. Used in what is for all intents and purposes a hospital setting. That automatically means hot water and Clorox."
My response to Covid-19: Everything is washed in hot. Whites get Clorox and Borax with vinegar as a fabric softener. Colours get ammonia instead of Clorox and Lysol/Dettol for a softener. All items are dried at the highest setting. Not one item, not even my 'ice silk' boxer briefs has shown the slightest bit of damage or shrinkage.
Of course, I'm limited to my building's Huebsch FL's so I have no way of knowing any of the actual temps involved. 'Hot' might well be warm, but that's just one more reason to crank everything to the hottest setting possible,
