Abstract

The new coronavirus called Covid-19, previously known as 2019-nCOV that has been reported in China, is rapidly spreading around the world at breakneck speed. Covid-19, a virus that was unknown to us before the outbreak in Wuhan (China) in December 2019, remains a major public health problem today. However, a new coronavirus named SARS-CoV-2 has been identified as responsible for this disease. Human-to-human transmission is no longer a matter of debate. In general, 2019-nCOV is an infectious, acute resolved disease, but it can also be very fatal especially with certain comorbidities such as hypertension, diabetes, coronary heart disease, cerebral infarction or even chronic bronchitis. The main symptoms of Covid-19 are fever, cough, shortness of breath, chest tightness / pain, respectively. Until now, the source of the virus and the pathogenesis of this disease remain unknown. Considering the speed of propagation, the mortality rate in the world and its economic consequences, it is urgent to find drugs for the treatment even a vaccine in order to cut short the Covid-19. In this article, we will try to detail all the information relating to this virus.
