In early December 2019, a coronavirus disease 2019 (COVID-19) outbreak in Wuhan City, Hubei Province, China, was caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). On January 30, 2020, the World Health Organization declared the outbreak a Public Health Emergency of International Concern. Coronavirus (COVID-19) is an enveloped RNA virus diversely found in humans and wildlife. Apart from infecting a variety of economically important vertebrates (such as pigs and chickens), six coronaviruses have been known to infect human hosts and cause respiratory diseases. In recent decades, endemic outbreaks of Middle East respiratory syndrome coronavirus (MERS-CoV) and severe acute respiratory syndrome coronavirus (SARS-CoV) have occurred (SARSCoV). Recently, the emergence of another outbreak has been attributed to a new strain called the SARS-CoV-2 virus. The most recent outbreak initially presented as pneumonia of unknown aetiology in a cluster of patients in Wuhan, China. The epicentre of infection was linked to seafood and exotic animal wholesale markets in the city. SARS-CoV-2 is highly contagious and has resulted in a rapid pandemic of COVID-19. As the number of cases continues to rise, it is clear that these viruses pose a threat to public health. This literature review reviews the history and origin of the causative agent, microbiology, pathogenesis of viruses, mode of transmission, symptoms, clinical diagnosis, treatment of the disease, and control and prevention strategies.
