  • Severity can be determined by assessing the activity level required to cause dyspnea (eg, dyspnea at rest is more severe than dyspnea only when climbing stairs). (msdmanuals.com)
  • If this is severe enough, the lungs can lose their ability to effectively transfer oxygen to the body. (rarediseases.org)
  • COVID-19 is primarily a respiratory illness, and a severe case can reduce the amount of oxygen that the lungs can absorb. (drakarun.com)
