SARS-CoV

SARS-CoV-2 is a virus that causes COVID-19, a respiratory illness first identified in late 2019. It spreads primarily through respiratory droplets when an infected person coughs, sneezes, or talks. Symptoms can range from mild to severe and may include fever, cough, and difficulty breathing. While many recover, it can lead to serious complications, especially in older adults and those with underlying health conditions. Vaccines have been developed to help prevent infection and reduce the severity of the disease. Public health measures, such as wearing masks and social distancing, are important in controlling its spread.
