I have just been considering issues of privacy related to remote medical appointments.
A few months ago, I had a phone appointment during which photographs of my issue were requested.
I had to use my phone to take the photos. I stood in front of a mirrored wardrobe door with the screen pointing at the mirror. By doing that, I could see the reflection of the screen and therefore judge the framing, angles, etc. (That bit worked amazingly well - but location on your body will dictate techniques required.)
I ended up with several photos on my phone, which were then copied to iCloud. And, on my Mac mini, I had to pick them up and send as email attachments. Plenty of room for mistakes (e.g. send to wrong email) and security loopholes (copies in iCloud, in Sent Items, etc.)
At some point, I think we will get a dedicated app for communicating with the doctor. It would be good if any such app could use the Continuity Camera feature to capture images/video and tell the phone not to store the images/video - just hand it straight across to the app. That is, you would know any images were as secure as possible. Especially good if the "no storage" mode could be set even without the app needing to be aware.
Obviously privacy can often be compromised in all sorts of ways and I'm not suggesting this is perfect. Just a considerable improvement on what is currently available.
That’s why telemedicine is distrusted. Some companies got hyped by this stuff in the financial press and their stock completely collapsed after this hype. People want to see a doctor in person. They want affordable care and medicine. They don’t want to speak to some remote doctor who might mishandle private photos and charge $100 a consultancy.
