When researchers in contrast the samples to historic information, greater than 1 in 10 sufferers had larger issue V ranges than had been seen earlier than on the hospital.

“Except for COVID-19, I’ve by no means seen anything trigger markedly elevated issue V, and I have been doing this for 25 years,” research co-author Dr. Elizabeth Van Cott stated in a hospital information launch.
