Study: SARS-CoV-2 Can Invade the Brain Through the Nose

In the study, published in Nature Neuroscience, scientists found small traces of SARS-CoV-2 viral material in the human brain which seem to have come through the nose. The scientists received these data based on a systematic analysis of 33 COVID-19 autopsies.Study SARS-CoV-2 Can Invade the Brain Through the Nose

This analysis showed intact viral particles within the endothelial cells of the nasopharynx, as well as viral RNA in the mucous membrane and several regions of the brain. This suggests the virus may somehow be hitching a ride past the blood-brain barrier and into the brain via the long, threadlike projections of olfactory nerves.

But even if it turns out that neurons in the nose are transporting the novel coronavirus to the brain, that is probably just one port of entry. In the analysis, some brain regions with traces of RNA held no direct connection to the olfactory mucosa and were more involved with respiration and cardiovascular control, which suggests the virus is entering through another means as well.
