Dear Mr. Farrar, i understand your concern, and just like you say there is an urgent need to change the behavior, but to say that chloroquine is obsolete is going to far. I studied medicine in Cuba and they still use it because Malaria is not resistant, also i'm practicing in Dominican Republic and Haiti and we use chloroquine. I think that one of the biggest problems is the over-diagnosis just as you say, but the pharmaceutical industry has gone way to far, because today you still can use penicillin in a great number of cases and we tend to used other antibiotics more expensive. I think that there is an impeding need to reassess the protocols. For example, nobody uses in the US chloramphenicol, due to resistance and medullary aplasia and it is still a common and effective drug in various countries.
