OLIVEIRA, Hélio A.; CARDOSO, João Cláudio F. and TEIXEIRA, Edda M.. Poliomyelitis in Sergipe (Northeastern Brazil). Arq. Neuro-Psiquiatr. [online]. 1994, vol.52, n.2, pp. 221-226. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X1994000200012.
A retrospective study of poliomyelitis in Sergipe, Northeast of Brazil, is presented by the authors. The study was divided in three periods, taking in consideration the notification rate of positive cases and emphasizing the period from 1979 to 1989 through the study of 159 consecutive cases. The following information was gathered for each case: sex, age, origin, former immunization status and clinical development. Also evaluated were annual incidence, relationship of incidence/vaccinal coverage and geographic distribution. Comments were made about the change in the wild poliovirus circulation (P1 to P3) and about epidemiological outbreaks occurred in 1984 and 1986, and problems related to the lack of immunity in children with complete vaccinal scheme. Poliomyelitis was considered to be controlled in the State of Sergipe but the necessity of maintenance of effective epidemiological vigilance for all cases of acute and flabby paralysis in children under 14 years is emphasized.
