Flu is a common viral infection that can be deadly, especially in high-risk groups.
The flu attacks the lungs, nose, and throat. Young children, older adults, pregnant women, and people with chronic disease or weak immune systems are at high risk for complications. Symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue.
The flu can be treated with rest and fluid allowing the body fight the infection on its own. There are medications that can be prescribed by your provider and natural remedies that can be used to treat the flu as well.
An annual vaccine can help prevent the flu and limit its complications.
