We count far more Covid related patients and deaths as Covid patients than lots of countries, so I don't understand how people think we're under counting by enough to be a worry. I would think it evens out if they missed someone because hospitals have been retroactively assigning Covid deaths as well, even without positive tests. I kind of lean to the side of "died of Covid; counts as Covid" side of the argument, and I know you aren't comparing other countries in this post, but we are far more liberal with Covid designations. Delaware had a Department of Health official say, "if you come into the hospital for a sprained ankle and you have Covid, you will be counted as a hospitalization." That just seems insane to me if an asymptomatic person just stopped by for an X-ray and went home to quarantine. Sure, if you know grandma had 8 months to live, but she died last week from Covid, that's a Covid death.
Just look up the thread. People are saying Spain is doing well, but they aren't counting in a similar manner. They are only counting patients with positive tests. Some countries won't count a Covid death if you have an underlying condition like diabetes or heart disease.
So maybe they miss a Covid patient or two here in the U.S., but I just disagree we are under counting overall.
