Fear not, that’s why we deploy extra security software to these critical systems. It’s called Crowdsource or something.

Maybe not everywhere, but all of ours are air gapped.

I’d heard some hospitals were affected. They cancelled appointments and non-critical surgeries.

I’m guessing it was mostly their “behind the desk” computers that got affected, not the computers used to control the important stuff. The computers in patients’ rooms may have been affected as well, but (at least in the US) those are usually just used to record information about medicine given and other details about the patient, nothing critical that can’t be done manually.
