COVID-19 Pandemic
Keywords:
SARS-CoV-2, COVID-19, Mutation patterns, Transmission mechanisms, Public health impact, Coronavirus structureAbstract
In December 2019, a mysterious outbreak of pneumonia emerged in Wuhan, China, with initial cases linked to a local seafood market. Subsequent investigations identified a novel coronavirus-later named SARS-CoV-2-through genomic analysis of respiratory samples cultured in human airway epithelial cells. The virus, distinguished by its crown-like protein spikes called peplomers, belongs to the beta-coronavirus group within the Sarbecovirus subgenus. This study explores various aspects of COVID-19, including its structure, mutation patterns, transmission mechanisms, methods of discovery, and the challenges it poses to global health in terms of morbidity, mortality, and public health preparedness.
