My mom got diagnosed with covid19 2 days ago. No symptoms, no fever, nothing. She's 64. For the past 50 years she's been suffering from hepatitis C which she only found out about 2 years ago. Since she's a health worker she had to take a vaccine 2 weeks ago. Any advice on diet or other things that can be done to protect her from any complications ? How does one virus interact with the other? Does anyone have any info?
