Overview
Influenza is caused by influenza viruses and can range from a mild illness to a more serious infection, particularly in older adults, young children, pregnant people, and those with certain chronic conditions.
Symptoms
Common symptoms include fever, chills, cough, sore throat, body aches, fatigue, headache, and sometimes vomiting or diarrhea, especially in children.
Causes & Risk Factors
Influenza spreads mainly through respiratory droplets and close contact. Risk can increase with crowded settings, limited ventilation, and certain underlying health conditions.
Diagnosis
Diagnosis is often based on symptoms and clinical assessment. Rapid or molecular influenza tests may be used when the result would change management.
Treatment
Treatment may include rest, fluids, symptom relief, and antiviral medicine for selected people when prescribed promptly. Severe symptoms require medical assessment.
Prevention
Annual vaccination, hand hygiene, improved ventilation, staying home while ill, and avoiding close contact with high-risk people when symptomatic can reduce spread.
