Cough, flu, and hay fever are common respiratory ailments. Coughs, often caused by viral infections or allergies, can be dry or productive. The flu, caused by influenza viruses, presents with symptoms like fever, body aches, and fatigue. Hay fever, or allergic rhinitis, results from allergens like pollen, triggering symptoms such as sneezing, congestion, and itchy eyes. Treatment approaches vary: coughs may be relieved with cough suppressants or expectorants, while flu often requires antiviral medications and supportive care. Hay fever responds to antihistamines, nasal sprays, and allergen avoidance. Vaccination against the flu can prevent its spread and severity.
