There are several potential complications of influenza that healthcare providers need to be aware of. These may include:
- Pneumonia: Influenza can lead to the development of pneumonia, which is an infection of the lungs. Pneumonia can be caused by bacteria or viruses, and can be severe, especially in older adults, young children, and people with underlying health conditions.
- Bronchitis: Influenza can also cause bronchitis, which is an inflammation of the bronchial tubes that can lead to coughing and difficulty breathing.
- Sinus infections: Influenza can cause inflammation of the sinuses, leading to sinus infections and related symptoms such as nasal congestion, headaches, and fever.
- Sepsis: In rare cases, influenza can lead to sepsis, a serious and potentially life-threatening condition caused by a widespread infection in the body. Sepsis can cause organ failure and can be fatal if not treated promptly.
- Reye's syndrome: Influenza can also cause Reye's syndrome, a rare but serious condition that can affect the liver and brain. Reye's syndrome is most commonly seen in children and adolescents, and can be fatal if not treated promptly.
