Aspirin is not an antiviral in any sense against SARS-CoV-2. It is an antiplatelet drug. In high risk cases, limiting platelet activation is extremely important.
Dipyridamole is another antiplatelet drug with a different and broader mechanism of action. It may also have antiviral effects.
It performed quite well in a Chinese COVID-19 RCT. A larger U.S. RCT is being conducted by @YogenKanthi and @jasonsknight.
The increasingly likely possibility that SARS-CoV-2 arose from a systematic gain-of-function study on the emergence of human pathogens from wildlife reservoirs does not invalidate the implications of the study.
Along with the post-exposure prophylaxis trials, this further indicates genuine antiviral activity in vivo for ivermectin (not merely anti-inflammatory).
Denmark orders military to kill all mink in the country after mutated, mink-passaged SARS-CoV-2 strain with supposedly poor antibody response (details pending) spreads back to humans.
Extensive prior culling was unsuccessful in halting mink infections.
