Lung and COVID-19

• pulmonary COVID-19
• Interstitial pneumonia
• Acute respiratory disease

SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is a major public health concern. COVID-19 is classified as an airway/multi-systemic disease, and its death has been linked to an out-of-control immune response and a cytokine storm. However, due to safety concerns, the lung pathology, immunological response, and tissue damage associated with COVID-19 death are poorly documented and understood. COVID-19 can lead to lung issues such pneumonia and, in the most severe cases, ARDS (acute respiratory distress syndrome). Another possible COVID-19 consequence is sepsis, which can cause long-term damage to the lungs and other organs. Newer coronavirus strains may potentially cause more severe airway disease, such as bronchitis, requiring hospitalisation. The pneumonia caused by COVID-19 tends to spread to both lungs. Shortness of breath, cough, and other symptoms result when air sacs in the lungs fill with fluid, reducing their ability to take in oxygen. While most people recover from pneumonia without any long-term effects, pneumonia caused by COVID-19 can be rather serious. Even when the disease is gone, lung injuries can cause breathing problems that take months to resolve. COVID-19 is a relatively new disease, and scientists are discovering more about its effects on the lungs every day.
