Epidemiology
Covid-19 is an infectious disease caused by the novel coronavirus SARS-CoV-2, first identified in Wuhan, China, in late 2019. It primarily spreads through respiratory droplets from coughs, sneezes, or talking, and can lead to a wide range of symptoms from mild respiratory illness to severe pneumonia and death. The pandemic has raised significant concerns about workplace hazards and occupational health, especially for essential workers and those in high-risk environments.
