COVID-19 hitches a ride on mucus to spread deep into lungs, live imaging shows.
Investigators observed that the movement of mucus can spread the COVID-19 virus inside the respiratory tract, where it later forms aerosols that infect other people.
“The most serious symptom is the potential for sudden, acute respiratory failure in individuals who may have previously only experienced mild to moderate symptoms.. Someone can appear to be recovering and suddenly face a rapid decline, often due to microvascular complications in the lungs, leading to severe oxygen deprivation.."
COVID virus evolves more rapidly in the CNS
New viral variants created in the brain & other parts of the nervous system could also travel back to the lungs, where they could become transmissible. That could spread new, dangerous variants of the virus.
