No, it hasn't.
There wasn't a sudden surge in people who went to a hospital because of a broken leg, got randomly tested for COVID-19 despite not showing symptoms, and were thus "mistakenly" classified.
The reality is that Texas opened up too early, causing a surge in cases and hospitalizations. The symptoms of having COVID-19 are all over the map, because it can cause widespread damage including clots and strokes. If someone shows up at the hospital because of a stroke or a heart attack, and they have COVID-19, they are almost certainly suffering from that condition because they had COVID-19.
By the way, Texas' positivity rate is very high, over 10%. That means Texas isn't testing enough.
And no, this is not normal. Texas hospitals have expanded capacity, and are still getting slammed. They're expecting 2,000 new hospitalizations per day very soon.
Stop the denials. COVID-19 is real.
