Since the SARS outbreak, research has taken place for a cure for SARS. they found hydroxycloroquine(hcq) to be effective at stopping the cold virus. the research was done by the Japanese and Koreans, and is believed to have been used in China. At present doctors are not prescribing this, and domestic trials have not been done. What is great about this- it is used against malaria and hence is vastly cheap – $0.05 a pill. Treatments being suggested by the CDC cost $5/treatment to $20/treatment. They are suggesting AIDS treatments – that cost $100K/year.
in the meantime, hcq is thought to be effective for it improves the absorption of zinc into the body. It might be quite effective to suck on zinc lozenges if you are an at risk individual. then the rest of us can go about our business.
