Cough Cold And Flu

Cough, cold, and flu are common respiratory illnesses with overlapping symptoms but different causes. The common cold is usually caused by rhinoviruses, leading to mild symptoms like a runny nose and sore throat. The flu, caused by influenza viruses, presents more severe symptoms, including high fever, body aches, and fatigue. Coughing can be a symptom of both conditions and serves as a mechanism to clear the respiratory tract. Preventive measures include good hygiene practices and annual flu vaccinations.
