A Literature Review in Understanding the Physio-Pathological Facet of COVID-19

In December 2019, a novel coronavirus, now named as SARS-CoV-2, caused a series of acute atypical respiratory diseases in Wuhan, Hubei Province, China. The disease caused by this virus was termed as COVID-19 and is transmittable between humans that has caused a pandemic worldwide. An early clinical report showed that fever, cough, fatigue, sputum production, and myalgia were initial symptoms, with the development of pneumonia as the disease progressed. COVID-19 basically involved the pulmonary system at the onset, thereby involving the other organs like gastrointestinal system, cardiovascular System and nervous system is based on virulence. Increases in the level of serum liver enzymes D-dimer, cardiac troponin I, and creatinine have been observed in severely ill patients, indicating that multiple organ failure had occurred in these cases. Here, we review the current knowledge about this disease in relation to its various aspects and make comparison systemic-wise for better understanding of the systemic physio pathological aspect of Covid-19 that may help in contributing towards finding the solution that is needed at present.
