Haemophilus influenzae type b (Hib) is the leading cause of meningitis in unvaccinated children; nontypeable strains cause URTI, and typeable strains cause invasive disease.
Haemophilus influenzae type b (Hib) is the most common cause of meningitis in unvaccinated children. Nontypeable strains cause URTI, while typeable strains cause invasive disease.
| Front | What is the MCC of meningitis in unvaccinated children? |
|---|---|
| Back | H.influenzae → nontypeable strains (lack a capsule) → associated with URTI such as acute and chronic otitis and sinusitis → nontypeable species lack a capsule so no vaccine can be made → typeable strains such as H. influenzae type b (Hib) cause invasive disease such as epiglottitis | pneumonia | meningitis in unimmunized individuals |
