A is for Aspirin

It's been around a long time and it's cheap. The Randomized Evaluation of Covid-19 therapy (Recovery) trial is set to test Aspirin's ability to stop the blood clots that sometimes endanger people with a Sars-CoV-2 infection (https://www.theguardian.com/science/2020/nov/07/aspirin-tested-uk-coronavirus-treatment-recovery-blood-clot). Daily low doses of Aspirin (acetylsalicylic acid) have long been advocated as a 'blood thinner', preventing heart attacks and stroke (also linked to blood clots). There is, consequently, a reasonable expectation that it will prove a useful and easily available medication for some Covid-19 patients.
