ABOUT THIS CONDITION
What is H1N1 / Swine Flu
H1N1, commonly known as swine flu, is a strain of the influenza A virus that causes a respiratory illness very similar to seasonal flu. It typically presents with fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and tiredness. While most patients recover with supportive care, H1N1 can cause severe disease, particularly in young children, pregnant women, the elderly, diabetics, and those with heart, lung or immune conditions. Severe disease can lead to pneumonia, breathing difficulty and respiratory failure. Early antiviral therapy, isolation, oxygen support if needed and annual vaccination are key elements of care. Dr. Patnam Pravallika Reddy provides complete H1N1 diagnosis, treatment and inpatient care at Lux Hospitals, Hyderabad.

AVAILABLE TREATMENTS
Treatment Options
Antiviral Therapy
Specific antiviral medication is effective when started early, particularly in high-risk patients and those with severe disease.
Supportive Care
Rest, fluids, fever control and symptom relief help most patients recover at home.
Isolation
Staying home and avoiding contact with others helps prevent spread, especially to vulnerable individuals.
Oxygen if Needed
Patients with breathing difficulty or low oxygen levels are given supplemental oxygen and closer monitoring.
Annual Flu Vaccination
Annual influenza vaccination is strongly recommended for high-risk groups and the general adult population to reduce the risk and severity of infection.
