Most people who get COVID-19 have mild or moderate symptoms like coughing, a fever, and shortness of breath. But some who catch the new coronavirus get severe pneumonia in both lungs.Jan 25, 2022
The pneumonia that COVID-19 causes tends to take hold in both lungs. Air sacs in the lungs fill with fluid, limiting their ability to take in oxygen and causing shortness of breath, cough and other symptoms.Feb 28, 2022
Lung damage in the course of this disease often leads to acute hypoxic respiratory failure and may eventually lead to acute respiratory distress syndrome (ARDS). Respiratory failure as a result of COVID-19 can develop very quickly and a small percent of those infected will die because of it.
Some people with COVID-19 develop abnormal blood clots, including in the smallest blood vessels. The clots may also form in multiple places in the body, including in the lungs. This unusual clotting may cause different complications, including organ damage, heart attack and stroke.Nov 3, 2021
COVID-19 Pneumonia Symptoms A fever, a dry cough, and shortness of breath are common early signs of COVID-19. You may also have: Fatigue. Chills.Jan 25, 2022
About 15% of COVID-19 cases are severe. That means they may need to be treated with oxygen in a hospital. About 5% of people have critical infections and need a ventilator..Jan 25, 2022
Most people who survive ARDS go on to recover their normal or close to normal lung function within six months to a year. Others may not do as well, particularly if their illness was caused by severe lung damage or their treatment entailed long-term use of a ventilator.
“Acute” respiratory illness is an infection of the upper or lower respiratory tract that may interfere with normal breathing, such as COVID-19. “Acute” means of recent onset (for example, for a few days), and is used to distinguish from chronic respiratory illnesses like asthma and chronic obstructive pulmonary disease (COPD).
Those suffering from post-acute sequelae of COVID-19 frequently have difficulty concentrating and memory problems, sometimes called “brain fog.” This impairment is a common symptom in those with severe fatigue of any cause.Feb 25, 2022
COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).Dec 22, 2021
COVID-19 can make blood cells more likely to clump up and form clots. While large clots can cause heart attacks and strokes, much of the heart damage caused by COVID-19 is believed to stem from very small clots that block tiny blood vessels (capillaries) in the heart muscle.
COVID-19 can cause lasting damage to multiple organs, including the lungs, heart, kidneys, liver and brain. SARS CoV-2 first affects the lungs through the nasal passages. When the lungs are severely affected, it can affect the heart.
