Abstract

Coronavirus disease (COVID-19) is an infectious disease caused by the newly discovered coronavirus. Coronavirus affects human lung tissues. Covid-19 should be infection of the lungs, the virus infects alveolar cells resulting in reduced production of pulmonary surfactant. Pulmonary surfactant is a complex of lipids and proteins that line the alveolar epithelial surface and stabilize it during respiration. The surfactant helps to reduce the surface tension on alveoli. The surface-active components of the alveoli are a complex mixture of specific lipids, proteins and carbohydrates, which is produced in the lungs by type II alveolar epithelial cells. As a result, the lungs continue to collapse, reducing its own volume, but the collapse is prevented by the muscles of inspiration, which instead increase its volume. Covid-19 allows the surfactant to maintain the correct amount of surfactant during the acute phase of infection during lung infection and allows time to resume and allow individual surfactant production for type II cells. Surfactant degradation or inactivation may contribute to increased susceptibility to pneumonia and increased susceptibility to infection. Surfactant deficiency in patients with acute respiratory syndrome in adults and surfactant administration may be a useful therapy against Covid-19.
