So you're saying we need to check all the mild cases for that 0.1% chance that they have the attenuated strain. You say that even the mild cases have the dangerous form of the virus most of the time. Do you think we could find the attenuated case more easily of we tested immune compromised people that have mild to no symptoms? Because if they did have the dangerous form of the virus, the symptoms wouldn't be mild. So we know that if you have the virus and are immunocompromised and have mild symptoms, it's probably not your immune system that is strong but the fact that the virus strain you have is attenuated? Or does that not work because the amount of people you can test that have those conditions is just too low to find any?
