I was reading the medical literature today about coronavirus and came across a paper by yao et al, 2020 who have just published a study that suggests that an existing anti-arthritis / anti-malarial treatment (Hydroxychloroquine) maybe effective against coronavirus. The paper is titled In Vitro Antiviral Activity and Projection of Optimized Dosing Design of Hydroxychloroquine for the Treatment of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). I know it relates to another coronavirus but I have seen comments that it maybe effective against Covid19.
Something to think about if you are an arthritis sufferer or your parents are but you'd have to go through your GP as this is not available over the counter.
It is not a vaccine but this paper suggests it maybe of use as an anti-viral treatment. Note though that this is a test-tube study and not a human trial however we already know the drug has been deemed safe for arthritis patients (subject to some side effects which maybe important for some people).
I post this hoping you will treat the information with caution, but interest. So far much of the news about Covid19 has been how a vaccine is 12 months away, but there are anti-viral treatments that I have heard are being used.
