In COVID-19, the arterial and general tissue oxygen levels can drop without any initial warning.The chest x-ray may show diffuse pneumonia.Cases of silent hypoxia with COVID-19 have been reported for patients who did not experience shortness of breath or coughing until their oxygen levels had depressed to such a degree that they were at risk of acute respiratory distress (ARDS) and organ failure.
[1] [2] Chronic mountain sickness may occur after long-term exposure to high altitude. [2] Altitude sickness typically occurs only above 2,500 metres (8,000 ft), though some people are affected at lower altitudes. [2] [4] Risk factors include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation. [2]
However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 metres (26,000 ft) as the death zone , where it is generally believed that no human body can acclimatize .

The findings, published by the U.S. Centers for Disease Control and Prevention, show that COVID-19 can still cause severe and fatal outcomes in children too young to be vaccinated.
Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who are at a higher risk or are more vulnerable to the effects of high altitude. Classically, HAPE occurs in persons normally living at low altitude who travel to an altitude above 2,500 meters (8,200 feet). [ 3 ]
A systematic review notes that children with COVID-19 have milder effects and better prognoses than adults. [ 2 ] [ 3 ] However, children are susceptible to " multisystem inflammatory syndrome in children " (MIS-C), a rare but life-threatening systemic illness involving persistent fever and extreme inflammation following exposure to the SARS ...
