Similarly, lots of people already have the disease, developing those immunities... but we don't know about it because they're asymptomatic... this is what would cause such a wide spreading of the disease... meaning the actual death rate is likely a fraction of what we're seeing.... not because the numerator is smaller, but because the denominator is a multiple of what is being reported.
