COVID-19, caused by the SARS-CoV-2 coronavirus, is a global infectious disease that emerged in late 2019 and reshaped public health, science, and society. It primarily affects the respiratory system but can impact multiple organs, leading to a wide range of symptoms from mild illness to severe complications. The pandemic spurred unprecedented scientific collaboration, driving rapid advances in virology, epidemiology, and vaccine development, including mRNA technology. Research into COVID-19 continues to reveal insights into viral evolution, immune response, long COVID, and pandemic preparedness. Its legacy continues to influence healthcare systems, global health policy, and biomedical innovation worldwide.
