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.
As COVID-19 pneumonia progresses, more of the air sacs become filled with fluid leaking from the tiny blood vessels in the lungs. Eventually, shortness of breath sets in, and can lead to acute respiratory distress syndrome (ARDS), a form of lung failure.
If your COVID-19 infection starts to cause pneumonia, you may notice things like:Rapid heartbeatShortness of breath or breathlessnessRapid breathingDizzinessHeavy sweating
Breathlessness is caused by an infection in the lungs known as pneumonia. Not everyone with COVID-19 gets pneumonia, though. If you don’t have pneumonia, you probably won’t feel short of breath.
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.
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. COVID-19 pneumonia is a serious illness that can be deadly.
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..

Look for emergency warning signs* for COVID-19. If someone is showing any of these signs, seek emergency medical care immediatelyTrouble breathingPersistent pain or pressure in the chestNew confusionInability to wake or stay awakePale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone*This list is not all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.
For most people, the symptoms end with a cough and a fever. More than 8 in 10 cases are mild. But for some, the infection gets more severe.About 5 to 8 days after symptoms begin, they have shortness of breath (known as dyspnea). Acute respiratory distress syndrome (ARDS) begins a few days later.
If you have a fever, a dry cough, and tiredness (with or without shortness of breath), you are likely to have COVID-19 until proven otherwise, and you should self-isolate
Some uncommon symptoms found in COVID-19, but reported during acute illness include congestion or runny nose, skin rashes and eye issues (including conjunctivitis, eye pain and light sensitivity).
