COVID-19, short for „Coronavirus Disease 2019,“ is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). First identified in December 2019 in Wuhan, China, it led to a global pandemic. COVID-19 primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. Symptoms can range from mild to severe and may include fever, cough, difficulty breathing, fatigue, loss of taste or smell, and more. Preventive measures to control its spread include vaccination, wearing masks, physical distancing, and hand hygiene. The pandemic has significantly impacted global health, economies, and daily life, prompting extensive public health responses and research into treatments and vaccines.
