Could the severity of COVID-19 be increased by low gastric acidity?

Could low gastric acidity increase the risk of a severe COVID-19 illness? Although it is primarily a respiratory infection, gastrointestinal involvement from swallowed coronaviruses is reported for SARS-CoV-2 (the virus of COVID-19 [12]), as well as SARS-CoV-1 [3] and MERS-CoV viruses [4].
The gastrointestinal tract may be a secondary route for spread to the lungs and other parts of the body. A possible hypothesis might be that the upper respiratory tract is attacked by viruses which are breathed in and coughed up in sputum while the lower respiratory tract is similarly infected, but is also attacked at the same time by blood-borne viruses (following translocation from a significant viral load in the gastrointestinal tract). The former might result in mild or moderate illnesses only. The latter may cause a more severe illness, as the lungs are being attacked by viruses coming from two routes simultaneously…
