The time to heal from novel coronavirus infection varies from person to person, depending on whether the individual’s immune system is strong enough. Some people with good immunity may develop low fever and mild malaise after being infected, and may recover spontaneously in about 1 week; some people may develop high fever, dry cough, shortness of breath, pneumonia and other symptoms after being infected, and may recover after a period of treatment; while some people with weaker immunity (elderly, chronic disease patients, cancer patients, etc.) may quickly develop acute respiratory distress syndrome, blood clotting dysfunction, or cause Some of the complications are even life-threatening.
