What is nontypeable Haemophilus influenzae?
Nontypeable Haemophilus influenzae (pronounced he-mo-FILL-us in-flu-EN-zay-ee) strains are a group of bacteria that are part of the normal flora of the human upper respiratory tract. However, they are also implicated in a wide range of diseases. Infections caused by nontypeable H. influenzae are major health and socioeconomic burdens. For example, lower respiratory tract infections caused by nontypeable H. influenzae strains are responsible for significant mortality in both infants and children in developing countries, and represent a major cause of morbidity in both developed and developing countries.
