Let me try to explain this once more. One, the efficacy of Chloroquine has not been established so far. It is only a suspicion. For instance, in the French case, out of the 985 cases who were not treated with chloroquine, 12 died. Among the 1003 who were treated with chloroquine, 1 died. The thing here is, we cannot establish with certainty that the fewer deaths in the second group was due to chloroquine treatment. To be certain, this exercise needs to be repeated with very many groups. The difference between the two groups is too small to be attributed to chloroquine. Why are doctors reluctant to go down this road? One, they could be giving patients false hope. Two, there could be unexpected reactions in patients. Three, lawsuits will certainly follow if the drug does not work. Four, it is careless to go by gut feelings in such matters.
