My dad just got a positive corona test result, but apart from a fever hovering around 99-100F, he doesn't really have any other symptoms. It's been a week since the test, and to be safe, we got an X-ray done. The report mentioned something about "Prominent branchovascular markings bilaterally." He's quarantining at home at the moment. Can you help me understand what those markings mean? Also, he's diabetic, but it's pretty well managed. I'm just trying to figure out if there's anything else we should be worried about.
