American experts said that more than a third of patients with the new epidemic "Corvid 19" who treat in New York hospitals had severe kidney failure, indicating that about 15 percent needed dialysis.

The study was conducted by a team at Northwell Health, the largest healthcare provider in New York State, according to Reuters.

"We found in the first 5,449 patients that 36.6 percent had severe kidney damage," said Dr. Kinar Jaffray, co-author of the study, who is co-chair of the Department of Pediatric Kidney Medicine at New York State Hospital.

The results of the study were published in the "Kidney International" scientific medical journal.

Acute kidney failure occurs when the kidneys stop functioning and are unable to clear fluids in the human body.

Of these patients with kidney failure, Jaffrey said in a telephone call, 14.3 percent needed dialysis.

This is the largest study of its kind so far delved into the study of kidney infections in patients "Covid 19" caused by infection with the Corona virus.

Jaffray said it may be beneficial as other hospitals face new waves of people living with the virus, which has infected more than 4.3 million people, and killed more than 295,000 worldwide.

Several groups have noted increased rates of kidney failure among "Covid 19" patients, and Jaffray and his colleagues examined the medical records of 5449 patients who entered hospitals between the first of March and the fifth of April. Jaffray said that kidney failure occurred in many cases around the time. In which patients needed to connect them with respirators.
