Glossary for Flu

  • Acute Bronchitis: Respiratory inflammation of the bronchi leading to the lungs
  • Acute Sinusitis: A condition which is characterized by an acute inflammatory reaction affecting the sinuses
  • Acute lower respiratory conditions: An acute condition that occurs in the lower respiratory tract
  • Adolescent conditions: Symptoms that are evident due to puberty
