What is COVID-19?
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. It primarily affects the respiratory system but can also impact multiple organs. The virus spreads through respiratory droplets, direct contact, and contaminated surfaces. While some individuals experience mild symptoms, others may develop severe complications such as pneumonia, acute respiratory distress, or multi-organ failure. COVID-19 led to a global pandemic, necessitating safety measures like social distancing, mask-wearing, and vaccinations to curb its spread.
