Carona is an offshoot of protein manipulation, it may be controlled with oral ingestion of iodine and Vit C with bioflavinoids, whole lemons may help also

Three drops of iodine for a 60kg person once a day for three days then three days off, Vitamin C with plant pigments, three tspns full 3 X a day until diarrhoea develops then little less dose, a glass of wheat grass juice and a whole lemon, no acid food, zinc and B vitamins, apart from the crelox system the above may help
