Current COVID-19 Statistics
Christopher Weaver, reporting for The Wall Street Journal:
All lab tests have some margin of error, measured in terms of sensitivity— the percent of positive cases a test accurately detects—and specificity, the percent of negative cases it accurately detects. […]
[Experts estimate] that the sensitivity of the tests is in the neighborhood of 70%, meaning nearly one in three positive patients walks away with a reassuring negative result.
It doesn’t take an epidemiologist to see why 30% of COVID-19 positive patients being told it’s safe for them to return to business as normal is a huge problem. On top of that, NPR reports that experts believe up to 25% of COVID-19 positive patients could be asymptomatic but still infectious.
One of the [pieces of] information that we have pretty much confirmed now is that a significant number of individuals that are infected actually remain asymptomatic. That may be as many as 25%.
These statistics are alarming by themselves, but combined… absolutely harrowing. As of today, the United States has 275,586 confirmed cases of COVID-19, and 7,087 Americans have died from it.
