Why COVID-19 patients have low oxygen levels; new infection mechanism holds answers

Of all complications that plague COVID-19 patients, decreased levels of oxygen is among the worst. Known as hypoxia, it is characterized by low oxygenation in the body's tissues, which makes the need for its constant monitoring paramount. Now, a new study has discovered an infection mechanism of the SARS-CoV-2 coronavirus that can explain the fall in oxygen levels among sufferers of the disease. According to scientists from the University of Alberta, the SARS-CoV-2 virus infects immature red blood cells (CD71+ erythroid precursors/progenitors, or CECs), thereby, reducing oxygen in the blood and impeding immune responses. The study also found why dexamethasone—an anti-inflammatory drug—has been effective in treating individuals struggling with the viral infection.........Read more
