Covid-19, caused by the SARS-CoV-2 virus, has significantly impacted global health and daily life since its emergence in late 2019. It spreads primarily through respiratory droplets and close contact. Symptoms range from mild to severe, including fever, cough, and difficulty breathing.

The pandemic has led to widespread lockdowns, economic challenges, and changes in public behavior. Vaccines have been developed to reduce severity and transmission. Ongoing research aims to manage long-term effects and future outbreaks.
