Haemophilus Influenzae (Hi) disease is caused by bacteria. The illness can range from mild to severe. Despite its name, Haemophilus influenzae has nothing to do with the influenza virus (flu). Typically, haemophilus influenzae bacteria cause a mild infection, but severe infection can occur when the bacteria get into parts of the body where they are not usually found. This includes the bloodstream and brain. This type of infection causes invasive Haemophilus influenzae disease. There are several types of Hi bacteria. Type b (known as Hib) can cause serious and life-threatening illness.
