ABOUT THIS CONDITION
What is Influenza
Influenza, commonly known as the flu, is a viral respiratory illness caused by influenza viruses, with annual seasonal outbreaks. It typically presents with sudden fever, chills, body and muscle aches, headache, sore throat, runny or stuffy nose, dry cough and significant tiredness. While most healthy adults and children recover within a week, flu can cause severe illness and complications in high-risk groups — including pneumonia, worsening of existing heart, lung or kidney conditions, and rarely, severe respiratory failure. High-risk groups include the elderly, pregnant women, young children, diabetics and those with chronic illnesses. Early antiviral therapy in high-risk or severe cases, combined with supportive care, improves outcomes. Annual influenza vaccination is the single most effective preventive measure. Dr. Patnam Pravallika Reddy provides complete flu diagnosis, treatment and vaccination at Lux Hospitals, Hyderabad.

Fever Control
Safe fever-controlling medication helps relieve high temperatures and ease body aches.
