If you try to hold your breath for a long time, it's not a lack of oxygen that forces you to breathe but the build-up of carbon dioxide in your blood. Whales and other animals can turn off this response, so can dive for extended periods. Covid 19 is perhaps doing this too, as some people are not feeling breathless but the levels of oxygen in their blood are dangerously low?
