What is COVID-19?

COVID-19 Definition

COVID-19 is a respiratory tract infection caused by the SARS-CoV-2 virus that rapidly spread to become a worldwide pandemic. COVID-19 is primarily transmitted via respiratory droplets when an infected individual coughs, sneezing, or speaking. It can also be transmitted by touching a contaminated surface and then touching the face.

COVID-19 may cause mild to severe symptoms, including fever, cough, fatigue, loss of taste or smell, and difficulty breathing. In severe cases, the virus can cause pneumonia, acute respiratory distress syndrome (ARDS), and even death, especially in older adults and those with preexisting conditions.

The recommended ways to slow virus transmission are to practice social distancing, wear masks in public, frequently wash hands, and avoid large gatherings to prevent the spread of COVID-19. Vaccines have been developed to help prevent infection and lessen the severity of the disease.

COVID-19 has significantly affected the world’s health, economies, and social systems. Governments and organizations implemented measures to prevent the spread of the virus and assist those affected.
