Please see a youtube video entitled: “LA doctor seeing success with hydroxychloroquine to treat COVID-19“”, wherein Dr. Anthony Cardillo says very sick from coronavirus patients need only 8- 12 hours treatment with HOQ AND ZINC to get completely well!
He also says prescribing doctors must use caution with heart patients.
He says HOQ alone, without ZINC does nothing for the c-virus.
PS in the Brazillian study, there was no zinc, and HOQ was not used, they used Chloroquine which is more toxic than HOQ, with the cardiotoxic antibiotics.
