Barnes Jewish Hospital in St Louis says Covid-19 lung failure cause is still mostly unknown, and only 4% of severe patients have a “cytokine storm“ like was originally reported by Chinese Wuhan hospitals:
With cytokine storm largely ruled out, the cause of most cases of respiratory failure in COVID-19 patients remains unknown, Mudd said.
"In the population we studied, 24% died but only 4% had a cytokine storm," Mudd said. "Most people who died of COVID-19 died without a cytokine storm. Severe flu is more inflammatory than severe COVID-19. So what's causing their lungs to fail? We still don't know. We're trying to find out."
