Study reveals how Covid affects the brain — Analysis

New research shows that Covid-19 is caused by the SARS virus-CoV-2 virus. It can travel from the respiratory system to the brain, heart, lung, brain, and almost every other organ in the body within days.

The research of the US National Institutes of Health team was described as “the” by the NIH. “most comprehensive analysis”To date, no data has been available on how the virus spreads throughout the body. Results were published in an online manuscript on Saturday, and are currently under review at Nature.

Based on the autopsies taken from 44 people who had died of Covid, scientists came up with their conclusions. Between April 26, 2020, and March 2, 2021, the autopsies took place.

The results of our collective research show that although the most severe form of SARS-CoV-2 infection is found in the lung and airways, this virus can spread quickly during infection to infect other cells, as well as the whole body.

Viral RNA was “widely distributed”The researcher said that even patients with mild or asymptomatic cases of Covid could have died. The virus could remain in some cases. “regions throughout the brain”For up to 230 consecutive days after symptom onset.

Ziyad Al-Aly, the director of the clinical epidemiology center at the Veterans Affairs St. Louis Health Care System in Missouri, told Bloomberg the study may provide an answer to why some patients suffer from so-called ‘long Covid’, when symptoms stay persistent for months.

“For a long time now, we have been scratching our heads and asking why long Covid seems to affect so many organ systems. This paper sheds some light, and may help explain why long Covid can occur even in people who had mild or asymptomatic acute disease,” Al-Aly said.
