Epidemiology and Prevention of Covid-2019

Abstract

COVID-19, caused by the SARS-CoV-2 virus, emerged in December 2019 and rapidly became a global pandemic. This review examines the epidemiology and prevention strategies associated with COVID-19. The virus is primarily transmitted through respiratory droplets, with a higher susceptibility observed in older adults and individuals with pre-existing conditions. Non-pharmaceutical interventions, including social distancing, mask-wearing, and hand hygiene, have proven effective in controlling its spread. Vaccination remains a key tool in preventing severe illness and death. Despite these measures, the emergence of new variants presents ongoing challenges. Continuous global efforts are essential to contain and manage the virus in the future.
