COVID-19

COVID-19 is an infectious respiratory illness caused by the novel coronavirus SARS-CoV-2. First identified in late 2019, the disease rapidly spread across countries, leading the World Health Organization to declare a global pandemic in March 2020.

COVID-19 primarily spreads through respiratory droplets and can cause symptoms ranging from mild illness to severe respiratory complications. Common symptoms include fever, cough, fatigue, and shortness of breath, while severe cases may require hospitalization and intensive care.

Governments worldwide implemented public health measures such as lockdowns, travel restrictions, and vaccination campaigns to control the spread of the virus. The pandemic had significant effects on healthcare systems, global economies, education, and social life.

Scientific efforts led to the rapid development of vaccines and treatments, marking a major achievement in global collaboration and medical innovation. COVID-19 remains an important topic in public health, with ongoing monitoring and research.
