I'm just a bit worried about my dad. He was positive for covid19 on December 3rd but thankfully tested negative by the 20th. Even though he's active and not complaining much, we decided to do a HRCT chest scan to be cautious. The results showed subpleural ground glass opacities in his bilateral lower lung lobes with a CT Severity Score of 0625 and Corads 4. He's been taking B complex, Vitamin C, and Vit D 60k for the next 20 days. Should we consider any other medications for him? Just trying to ensure we're not overlooking anything important.
