C-virus

C-virus, often called COVID-19, is a contagious respiratory illness caused by the coronavirus SARS-CoV-2. It spreads primarily through respiratory droplets when infected individuals cough, sneeze, or talk. Symptoms can range from mild (fever, cough, fatigue) to severe (difficulty breathing, pneumonia), and some people remain asymptomatic. The virus can lead to serious health complications, especially in older adults or those with underlying conditions. Preventive measures include wearing masks, practicing good hand hygiene, maintaining physical distance, and vaccination. Public health efforts aim to reduce transmission and manage healthcare systems during outbreaks.
