I'd carry my own and be judicious with its use. You have to touch the dispenser, which is presumably done by many others. Repeated use and over use of the alcohol based sanitizers can dry out and crack your skin, making you more susceptible to infection. Ironic, huh?
Overdoing cleanliness is now viewed by some researchers as a bad idea. Kids need to be exposed to dirt, germs, sick people, etc. to build up immunities.
Some speculate that increases in allergies may be caused by the child being too clean when young.
In a deadly illness situation, though, I would go with cleanliness.
As a kid, I made pigs look dirty. I swam in Lake Erie 50 years ago and since it didn’t kill me, it made me stronger. We live right next to a sewage plant discharge. During heavy rains, it couldn’t handle the volume and it went into the lake. When it stopped raining, my friends and I swam in it. Yummy! Just push those turds out of the way.
