Autopsies Present Covid Virus Lingers In Mind, Different Physique Elements For Months: Research

Washington:

The SARS-CoV-2 virus spreads all through the physique, together with the mind, and lingers for nearly eight months, exhibits an evaluation of tissue samples from the autopsies of people that died resulting from COVID-19.

The researchers from the US Nationwide Institutes of Well being (NIH) examined samples from autopsies that have been carried out from April 2020 to March 2021.

They detected SARS-CoV-2 RNA and protein within the hypothalamus and cerebellum of 1 affected person and within the spinal twine and basal ganglia of two different sufferers.

Nonetheless, the research discovered little harm to mind tissue, “regardless of substantial viral burden.” The researchers additionally remoted viable SARS-CoV-2 virus from various tissues in and out of doors the respiratory tract, together with the mind, coronary heart, lymph nodes, gastrointestinal tract, adrenal gland, and eye.

They remoted virus from 25 of 55 specimens examined (45 per cent).
