The COVID-19 resource centre, hosted by Elsevier, provides free information in English and Mandarin on the novel coronavirus. Elsevier grants permission to make all COVID-19-related research available in PubMed Central and other public repositories, with unrestricted reuse and analysis rights. The review article by Hussin A. Rothan and Siddappa N. Byrareddy discusses the epidemiology, pathogenesis, transmission, phylogenetic analysis, and future directions for controlling the spread of COVID-19. The disease, caused by SARS-CoV2, emerged in Wuhan, China, and has spread globally, with a high case fatality rate. Symptoms include fever, cough, and fatigue, and the virus targets the respiratory system, leading to severe pneumonia and acute cardiac injury. Person-to-person transmission is a significant concern, and efforts are being made to develop treatments and vaccines. Phylogenetic analysis suggests that COVID-19 belongs to the betacoronavirus genus, likely originating from bats. Current therapeutic options include broad-spectrum antiviral drugs, and ongoing research aims to identify novel treatments and develop animal models for further study.The COVID-19 resource centre, hosted by Elsevier, provides free information in English and Mandarin on the novel coronavirus.
