Abstract
COVID-19 is a contagious disease caused by the coronavirus that causes severe acute respiratory syndrome. COVID-19 was first identified at the end of 2019, and the disease has since spread far and wide, resulting in an on-going pandemic. Patients with COVID-19 presented with a variety of complaints, the most common of which were fever, cough, exhaustion, breathing difficulties, and loss of smell and taste. Patients typically start noticing changes in their health one to fourteen days after infection. Among those who experience changes in their health, the majority (81%) develop mild to moderate symptoms (up to mild pneumonia), while (14% develop severe symptoms) (dyspnoea, hypoxia, or more than 50% lung involvement on imaging) and 5% suffer critical symptoms (respiratory failure, shock or multi-organ dysfunction). At least 33% of those infected with this disease are asymptomatic and therefore do not experience or exhibit symptoms during the infection, despite the reality that they too can spread the disease. Some people continue to face a variety of effects known as long COVID for quite some time after recovery, and serious harm to organs has been observed. Studies are being conducted to learn more about the disease's long-term effects. SARS-CoV-2, like its homologous virus, SARS-CoV, which caused SARS in thousands of people in 2003, may well be transmitted from bats and lead to similar symptoms via a similar mechanism. COVID-19, on the other hand, has a lower severity and mortality rate than SARS but are much more communicable, negatively impacting more elderly people than youth and more men than women. I hope that this review contributes to a better understanding of COVID and the eradication of this dangerous disease.
