COVID-19 | SARS-CoV-2 virus lingers in brain, other body parts for months: Study

The study also showed that SARS-CoV-2 primarily infected and damaged airway and lung tissue.

The blood plasma of 38 patients tested positive for SARS-CoV-2, three tested negative, and plasma was unavailable for the other three.

Health News: There are several research and studies going on around the coronavirus in order to understand how it affects the human body. An analysis of tissue samples from the autopsies of people who lost their lives after being infected with COVID-19 showed that the coronavirus spreads throughout the body, including the brain. It was also found that the SARS-CoV-2 virus lingers for almost eight months.

The samples were tested by researchers from the US National Institutes of Health (NIH). They took samples from autopsies that were performed from April 2020 to March 2021.

Extensive sampling of the nervous system, including the brain, was done by the researchers in 11 of the patients. It is worth mentioning that all the patients who died because of COVID-19 infection were not vaccinated.

The blood plasma of 38 patients tested positive for SARS-CoV-2, three tested negative, and plasma was unavailable for the other three.

Out of this, thirty per cent of the patients were female, and the average age was 62.5 years.

Twenty-seven patients (61.4 per cent) had three or more comorbidities. The study, which was published in the journal Nature, found that the average interval from symptom onset to death was 18.5 days.

The study also showed that SARS-CoV-2 primarily infected and damaged airway and lung tissue.

However, the researchers also found viral RNA in 84 distinct body locations and bodily fluids, and in one case they isolated viral RNA 230 days after a patient’s symptoms began.
