A comprehensive review on epidemiology, aetiopathogenesis, diagnosis and treatment of the novel coronavirus syndrome – COVID-19

Since the outbreak of the novel Coronavirus in December 2019 in Wuhan China, this novel Coronavirus disease(COVID-19) has spread worldwide taking not only epidemic proportions but with its rapid spread world health organization(WHO) was forced to declare it as a pandemic. The Severe Acute respiratory syndrome (SARS)-Coronavirus (CoV2) virus is responsible for clusters of severe respiratory illness that simulates acute respiratory syndrome that was what was initially. It is thought although that it is equivalent to the high altitude pulmonary oedema (HAPE), showing glass ground opacities in lungs. More experience is getting acquired with changes in treatment approaches from PEEP to avoid intubation and just ensure oxygen levels maintained. Human to human transmission through droplets, contaminated hands as well as surfaces, has been revealed with an incubation period varying from 2-14 days. Early diagnosis using reverse transcription polymerase chain reaction (RT-PCR) or computed tomography (CT) scan chest, quarantine, as well as supportive treatment are necessary for getting a cure. In this review we have tried to analyze the epidemiology, diagnosis, isolation, and treatment, including antiviral drugs like remdesivir, favipiravir, chloroquine and hydroxychloroquine, corticosteroids, antibiotics, and ivermectin. With 3 successful cases of convalescent plasma achieved in USA, trials going on in India along with vaccines are also detailed in this article
