Haemophilus influenzae type b: epidemiological situation in the State of Minas Gerais, Brazil, 1993-1997. Cad. Saúde Pública [online]. 2003, vol.19, n.5, pp. 1267-1275.

Among Haemophilus influenzae type b (Hib) invasive diseases, pneumonia and meningitis are the most relevant in public health due to their frequency and severity. From 1993 to 1997, there were 720 cases of Hib meningitis in Minas Gerais State, Brazil, representing the most frequent cause of bacterial meningitis in infants (< 1 year) and the second most frequent among all causes of meningitis. The total estimated cases of invasive Hib diseases thus appear to justify the recent inclusion of the vaccine in the basic immunization protocol. The vaccine's high cost reinforces the need for more precise monitoring of the etiological diagnosis of meningitis cases, representing one of the weaknesses in the prevailing epidemiological surveillance system.
