The effects of the novel coronaviruses are not limited to a single organ.
Remnants of the novel coronaviruses were found in a patient's brain after they first showed symptoms.
According to the authors of the study, some patients can cause systemic infections and persist in the body for months.
In the past, autopsies on those who have contracted COVID-19 have shown evidence of multi-organ spread, with genetic remnants of the virus showing up in a variety of tissues, organs, and fluids.
Blood clot evidence was found in nearly all of the vital organs of those who had contracted COVID-19.
The new research confirms the results more thoroughly than before.
According to the researchers, their newest findings are the most comprehensive analysis to date on the cellular persistence of the disease.
The study involved 44 autopsies in which researchers carefully detected and quantified the level of messenger RNA from the disease. The genetic information shows where the virus might have been replicating.
Researchers found that older, unvaccinated individuals who died from COVID-19 had signs of the disease in a number of locations.
Some of the changes could be seen within two weeks after the first symptoms appeared.
While the lungs showed the most inflammation and injury, the brain and other organs didn't show much tissue changes.
The authors do not know why that is. It's possible that the human immune system isn't as good at targeting these other locations.
In the later stages of COVID-19 recovery, it was found that the lungs were less infectious than first thought.
The researchers concluded that the virus can be spread throughout the body.
There is a mystery about how the virus spreads. The pathogen may be traveling around via other means after the autopsies in the current study didn't show many viral remnants.
Some patients suffer from long-haul COVID-19 because of the way in which SARS-coV-2 spreads.
The results of the research are relevant to possible treatment plans.
The human immune system can clear viral cells from tissues, organs, and fluids that are otherwise difficult to reach.
It could help reduce the symptoms.
The National Cancer Institute is trying to replicate the data on viral persistence and study the relationship with long carbon dioxide.
In less than a year, we have 85 cases, and we are trying to expand these efforts.
The study was published in a scientific journal.
