COVID is a contagious respiratory disease caused by the SARS-CoV-2 virus. It spreads through droplets and close contact, causing symptoms like fever, cough, fatigue, and loss of taste or smell. While many recover, severe cases can lead to complications. Vaccination, mask use, and good hygiene help prevent infection. Early testing and treatment are key to controlling COVID and protecting high-risk individuals from serious illness. Stay alert and safeguard your health.
