Flu Symptoms and Treatment: Who Is High Risk and Needs Extra Care

Overview

The flu, or influenza, is a contagious respiratory illness caused by influenza viruses. Common flu symptoms include fever, chills, cough, sore throat, muscle aches, fatigue, and headache. Understanding flu symptoms and treatment is essential, especially for those at higher risk, such as the elderly, young children, and individuals with chronic health conditions. While medical treatments are available, many people also seek home remedies for flu symptoms and treatment. However, it is crucial to remember that home remedies are meant to support your health and do not replace professional medical advice.
