The virus primarily affects the respiratory system, causing symptoms such as fever, cough, fatigue, sore throat, and shortness of breath. While children and teenagers often experience mild symptoms, the elderly are at higher risk of severe complications. The virus spreads easily through respiratory droplets and can survive on surfaces for several days. Preventive measures include regular handwashing, maintaining social distance, covering coughs and sneezes, and avoiding touching the face. There is currently no specific treatment or vaccine, but ongoing research aims to develop effective treatments and vaccines. The article emphasizes the importance of individual actions to prevent the spread of the virus and protect vulnerable populations.COVID-19, or coronavirus disease 2019, is a pandemic caused by the SARS-CoV-2 virus, first reported in Wuhan, China, in November 2019.
