Multiple studies now indicate that increased risk of pulmonary fibrosis followed a severe COVID-19 infection and is mainly observed in patients with comorbidities such as diabetes, hypertension, or coronary disease [8].
COVID-19 can cause lung complications such as pneumonia and, in the most severe cases, acute respiratory distress syndrome, or ARDS. Sepsis, another possible complication of COVID-19, can also cause lasting harm to the lungs and other organs.
Bilateral interstitial pneumonia is a serious infection that can inflame and scar your lungs. It's one of many types of interstitial lung diseases, which affect the tissue around the tiny air sacs in your lungs. You can get this type of pneumonia as a result of COVID-19.
Initial presentation — Among patients with symptomatic COVID-19, cough, myalgias, and headache are the most commonly reported symptoms. Other features, including diarrhea, sore throat, and smell or taste abnormalities, are also well described (table 3).
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.
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).
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.
Multisystem inflammatory syndrome (MIS) is a rare but serious condition associated with COVID-19 in which different body parts become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal organs. MIS can affect children (MIS-C) and adults (MIS-A).
Symptoms. People with post-COVID conditions (or long COVID) may experience many symptoms. People with post-COVID conditions can have a wide range of symptoms that can last more than four weeks or even months after infection. Sometimes the symptoms can even go away or come back again.
Mild Illness: Individuals who have any of the various signs and symptoms of COVID-19 (e.g., fever, cough, sore throat, malaise, headache, muscle pain, nausea, vomiting, diarrhea, loss of taste and smell) but who do not have shortness of breath, dyspnea, or abnormal chest imaging.
Symptoms may appear 2 to 14 days after exposure to the virus.
The possibility of long COVID. While omicron may cause less severe symptoms, this may not mean a decreased risk of long-term sickness.
