Wildlife water in light of avian flu

The weather is warming up and it’s good to put out water. Especially now I’ve got magpies here.

However I stopped doing it because of potential disease transmission with avian flu. (Especially owning a vulnerable elderly cat - who is kept indoors but could get sick if I tracked something in.)

I’m physically disabled so would have trouble cleaning and disinfecting the water containers daily.

What’s everyone else’s plan for managing this?
