True. The problems come from the inflammation caused by the viral "garbage" that is toxic to your blood and tissues. Plus they invade critical cells and the lack of said cells i.e. red or white blood cells isn't healthy. Cancer for instance. Relative survived but has ongoing issues with his body temperature and low red corpuscle count, and his vitamin D was extremely low. Interesting that the natural remedies for cancer seek to control the PH of the blood, i.e. a more alkaline state by avoiding certain things in your diet.
