Haemophilius influenzae, all types

Haemophilus influenzae is a bacteria that has six strains (types “a” through “f”), as well as strains that cannot be typed; type b (Hib) is the most serious. Hib is spread through contact with respiratory droplets and nasal or throat discharges. Hib can cause meningitis and other serious infections, particularly in young children. In Ontario, a vaccine series to prevent Hib disease is given to infants and toddlers and the disease is now uncommon.
