All things considered, COVID has a 99.9 percent survival rate. Ebola, on the other hand, has a 50-60 percent survival rate. This could have been a lot worse.
covid is actually about 92-98% survival
however with interventions this 3-8% deathrate comes down to percentages you mention
yep social distancing, isolating and masks has reduced viral load amounts. meaning less of a severe fight to battle
also getting those remaining severe people to a hospital and given oxygen treatments and other stuff reduces it to your quoted amounts
but take for instance the incidences in the cruise ships a year ago and in nursing homes that dont follow social distancing and dont offer taking residents to hospital due to DNR. the death rate is 2-8% in those not having any medical/health precautions to mediate the risk
so thinking masks aint needed and hospitals are not needed due to your presumed 0.1%.. is wrong. its only now down to 0.1% because of the social restrictions, masks and healthcare
