Influenza is a viral infection that attacks your respiratory system — your nose, throat, and lungs. Influenza is commonly called the flu, but it's not the same as stomach "flu" viruses that cause diarrhea and vomiting.
For most people, the flu resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include:
Young children under age 5, and especially those under 6 months
Adults older than age 65
Residents of nursing homes and other long-term care facilities
Pregnant women and women up to two weeks after giving birth
People with weakened immune systems
Native Americans
People who have chronic illnesses, such as asthma, heart disease, kidney disease, liver disease, and diabetes
People who are very obese, with a body mass index (BMI) of 40 or higher
Though the annual influenza vaccine isn't 100% effective, it's still your best defense against the flu.
