The difference is easy. It’s an aerosol. Known leaks from biological weapons programs are mostly things like anthrax.

That also makes the biological warfare scenario less likely — armies like to control where the bomb goes.

The other factor to discount this conjecture is that if you hear about covid as a biological weapon, it’s less likely to be true as it would potentially expose research in other places. If China is doing this, the US, Russia and others are too.
