Answer:
The present outbreak associated with corona virus [CoVs] in China which is believed to be one of the massive eruptions towards mankind in 2019–2020. In the present scenario CoVs has been transmitted to the European and American regions through the travellers from wide spread countries like China and Japan. The viral disease is spreading through the contact in any form by the infected persons or patients and creating huge risk of mortality. CoVs are a single positive-sense RNA virus; mutation rates are higher than DNA viruses and indicate a more effective survival adaption mechanism. Human CoVs can cause common cold and influenza-like illness and a variety of severe acute respiratory disease such as pneumonia. Early in infection, CoVs infects epithelial cells, macrophages, T-cells, dendritic cells and also can affect the development and implantation of pro-inflammatory cytokines and chemokines. It mainly produces the melanoma differentiation associated with protein-5, retinoic acid inducible gene-1 and endosomal toll-like receptor 3. How CoVs affects the function of the immune system is still unclear due to lack of this knowledge. No Food and Drug Administration approved treatment is available till date. In this review, we are tried to explore the epidemiology, pathogenesis and current treatment of CoVs infection. The promising therapeutics molecules against CoVs and future prospective have been also discussed which will be helpful for researchers to find out the new molecules for the treatment of CoVs disease.
