Buy 2000 grams of vitamin C for everyone in your family. If SARS because pandemic, start taking 1 gram of vitC every waking hour until diarrhea occurs, then wait 2 hours and resume 1 gram per hour until diarrhea occurs, rinse and repeat until the pandemic has subsided. Also, a Keto diet is recommended to maximize the amount of vitC your white blood cells can uptake. Fat does not compete with vitC, whereas sugar carbs, complex carbs and protein do. Sugar carbs are the worse, followed by complex and then protein.
