Certain gut-dwelling fungi flourish in severe cases of COVID-19, amplifying the excessive inflammation that drives this disease while also causing long-lasting changes in the immune system, according to a new study led by investigators at Weill Cornell Medicine and NewYork-Presbyterian.

Convalescent plasma did not reduce the risk of intubation or death for hospitalized COVID-19 patients in a large, international clinical trial conducted by Weill Cornell Medicine and NewYork-Presbyterian investigators in collaboration with lead investigators at McMaster University.

In March, as the COVID-19 pandemic gained a visible foothold in New York City, Weill Cornell Medicine and NewYork-Presbyterian faced a task unlike any they had encountered before: How would they quickly establish a reliable diagnostic testing program to identify patients and healthcare workers who had been exposed to SARS-CoV-2 amid a rapidly escalating public health crisis? 

Blood transfusions are historically one of the most common—and most overused—hospital procedures in the United States.
