has little expression in the brain.
There has been hypotesis that
other routes of CNS infi ltration
might account for the respiratory
failure caused by infection with
SARS-CoV-2, although there isn’t,
actually, evidence.There is prelimi-
nary in-vitro evidence that SARS-
CoV-2 can replicate in neuronal cel-

to in-vivo settings remains unclear.
Previous infl uenza pandemics
have been associated with long-la-

ces, so it is possible that other viral
infections on a large scale could
cause sustained mental morbidity.
From a systematic review and me-
ta-analysis of the psychiatric con-
sequences of coronavirus infection
published by “The Lancet” in May
2020, were identifi ed 72 indepen-
dent studies that provided data
on both the acute and post-illness

preprints (Medrxiv is an Internet
