The neuroinvasive potential of SARS‐CoV2 and Covid-19 symptoms

If this is true, then it's very interesting. I'd love to find a more recent update on this, if there is any.

TL;DR: Contracting the virus through your nose might be much worse than through the eyes or stomach.

Quote:

If the neuroinvasion of SARS‐CoV‐2 does take a part in the development of respiratory failure in patients with COVID‐19, the precaution with masks will absolutely be the most effective measure to protect against the possible entry of the virus into the CNS. It may also be expected that the symptoms of the patients infected via fecal‐oral or conjunctival route will be lighter than those infected intranasally. The possible neuroinvasion of SARS‐CoV‐2 may also partially explain why some patients developed respiratory failure, while others not. It is very possible that most of the persons in Wuhan, who were the first exposed to this previously unknown virus, did not have any protective measure, so that the critical patients are much more in Wuhan than in other cities in China.

Another interesting quote:

According to the complaints of a survivor, the medical graduate student (24 years old) from Wuhan University, she must stay awake and breathe consciously and actively during the intensive care. She said that if she fell asleep, she might die because she had lost her natural breath.
