I live in Mexico, our neighbor and friend is a doctor (young), he works in a hospital treating covid patients. He told us and his family that hc works, his family is from a small town in mexico where they have a drug store. He told them to keep all the hc for themselves just in case. The virus eventually reached their community and the whole family was infected, including the 80 year old grandma. They used hc as our doctor friend said and they all recovered, even the grandma.
