If a person has digestive symptoms, these may occur before other symptoms, such as respiratory ones. Overall, it is important to keep in mind that COVID can present atypically and that the symptoms can vary greatly from person to person. The incubation period, the amount of time between exposure to the virus and developing symptoms, is up to 14 days. But many people begin to experience symptoms within 4—5 days.
Some research indicates that difficulty breathing occurs, on average, 5 days after the first COVID symptom appears, in people who require hospital care for the disease. Shortness of breath, like some other COVID symptoms, occurs because of how the disease affects the lungs.
Normally, the lungs take in oxygen with each breath and tiny air sacs called alveoli capture this oxygen and transfer it to nearby blood vessels. In this way, oxygen enters the bloodstream and reaches the rest of the body. The alveoli also absorb carbon dioxide from the blood, and this is exhaled. The immune system responds by releasing cells that cause inflammation in the affected tissues. When this inflammatory immune response continues to happen, it inhibits the regular transfer of gases , including oxygen, in the lungs, and fluid can build up.
Each person with COVID experiences it differently — and not all breathing issues mean that the disease is serious. Shortness of breath may be mild, similar to that resulting from a cold or the flu. In this case, it is important to stay home and rest. If any breathing issue seems serious, especially if it rapidly worsens, seek medical attention. Some signs that this is necessary include:.
A person may need emergency treatment if they:. The tube is connected to a machine called a ventilator that helps the person breathe. Other treatments aim to help control the infection and address problems involving the blood and the functioning of other organs. Stay safe and keep logging. Discover more about your health.

A variety of health conditions can trigger shortness of breath. On average, shortness of breath tends to set in around 4 to 10 days after you contract an infection with the new coronavirus. Shortness of breath may be mild and not last long. But, in other cases, it may lead to pneumonia, ARDS, and multi-organ dysfunction or failure.
These are potentially life threatening complications. All episodes of shortness of breath must be taken seriously. Be sure to call your doctor right away if you have any concerns about how to manage this symptom. Some people with COVID have presented with less typical symptoms, including nausea, diarrhea, delirium, chickenpox-like lesions, and more.

The novel coronavirus can enter your body through your eyes, in addition to your nose and mouth. But because most patients do not have a high-quality oximeter at home, a majority of this information can be taken through a patient's history.
Some examples of questions may be "is there anything you can't do today that you could do yesterday" or even "what are you able to do at home," Cohen noted.
However, the authors noted that dyspnea related to COVID presents differently from dyspnea associated with other illnesses.
