ABSTRACT
The most discussed topic in today's world is COVID-19, an acute respiratory disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) because of its contagious transmission pattern, and morbimortality. The virus was originated by bats and in December 2019, first spread to humans by unknown intermediate species in Wuhan, China. The dramatic acceleration of the occurrence and death toll of COVID-19 with no potential medicine and vaccine are enough to explain its severity. This review summarizes multidisciplinary aspects of COVID-19, including origin, epidemiology, symptoms, transmission, pathogenicity, impact on world economy and advances in the use of modern diagnostic procedures and methods. Further, we analyzed extensively for various therapeutic strategies, potential drug options with prospective vaccine candidates and challenges along the way. All data were accumulated through extensive study of recent peer-reviewed publications and authentic reports until June 7, 2020. Collectively, this review would help to shed light on different dimensions of this ongoing pandemic.
ABSTRACT
The COVID-19 virus is transmitted through close contact between people, via droplets and possibly via airborne transmission. Wearing a mask is one of the recommended preventive measures that can reduce the transmission of COVID-19. But due to panic buying and increased demands, the health institutes are facing severe shortages of these PPEs. This article reviews the types of masks available, the feasibility of reusing them and the dos and don'ts of each suggested method.
