@-fish-'s request to you was "Would you mind talking to her children to tell them her risk of death is almost 0?" (see the bolded above).
As someone in her late 30's who has been hospitalized by COVID-19, her chances of dying are NOT near zero. Near zero is the chances of dying of ALL 30's who have tested positive.
Again, we can ignore 96.6% of all 30's who have tested positive to calculate her current risk of death. Take the risk of death for all 30's who have tested positive and divide it by 0.034.
Having been hospitalized by the virus, she currently has around a 3% chance of dying from it. Her kids should be worried. It's not extremely improbable that she could die (it's 3%). Nor was it extremely improbably that she got hospitalized by it (it was 3.4%). And unless we develop a vaccine, 70% or more of the population has to get it in order for us to exit this crisis (herd immunity).
