Review Paper: Recent developments in corona virus disease-2019 (Covid-19)

A respiratory illness by SARS-Co-V2 affected more than millions of people across the globe and killed thousands of people. This outbreak had believed to start in sea food market of Wuhan, China, during the sales of animals in the market and the virus had started spreading. The reservoir host for the virus is bats and from there it transferred to human through an intermediate host. The spread and transmission of the virus will be through direct contact of infected droplets or by inhalation which has a period of incubation about 2 to 14 days. The symptoms for the disease include cough, fever, sore throat, fatigue, difficulty in breathing, malaise and others. Most of the affected people will be asymptomatic, in adverse condition it may lead to acute respiratory distress syndrome, pneumonia and multiple organ dysfunction. Molecular methodology and CT scan are the usual diagnostic procedure. The ancestor of this virus is MERS-CoV and SARS-CoV. It is uncertain to determine the impact of this epidemic. Since there was no prominent treatment identified for treating the condition, it was spreading rapidly. The aim of this review is to give insights on epidemiology, virology, pathogenesis and available modern and traditional medicines for COVID-19.
