Haemophilus influenzae (vaccine-preventable)


Until recently, Haemophilus influenzae (HIB) was one of the most important causes of bacterial infection in young children. HIB may cause a variety of diseases such as meningitis (inflammation of the coverings of the spinal column and brain), blood stream infections, pneumonia, arthritis and infections of other parts of the body. Due to widespread use of HIB vaccine in children, very few cases of HIB are now reported each year in Oregon. Childhood immunization is recommended.

Disease Reporting

What is required?

Health-care providers and clinical laboratories are required to report cases and suspect cases of Haemophilus influenzae to local health departments within 24 hours of identification.
