Abstract
The coronavirus disease (COVID-19) is a highly transmittable and viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which arises in Wuhan, China and spreads all around the world. The Genomic analysis shows that SARS-CoV-2 is related to severe acute respiratory syndrome- like (SARS-like) bat viruses, so bats could be the possible primary reservoir for this disease. The intermediate source of origin is not known, the rapid human to human transfer has been confirmed largely. Most adults or children with COVID-19 infection are with mild flu-like symptoms and a few patients are in critical condition and develop acute respiratory distress syndrome, respiratory failure, multiple organ failure, even death of the individuals. The most commonly reported Symptoms are fever, cough, myalgia or fatigue,pneumonia, and complicated dyspnea,where's less common reported symptoms include headache, diarrhea, halmoprysis, runny nose, and phlegm producing a cough. Still There is no clinically approved antiviral drug or vaccine available for COVID-19.Few broad-spectrum antiviral drugs have been evaluated against COVID-19 in clinical trials, resulting in clinical recovery. The current review is about the history of covid 19.
