Resumo: | The purpose of the study was to estimate the prevalence of IgG antibodies against varicella zoster virus (VZV) in the two most populated indigenous ethnic groups from Xingu Indigenous National Park, in Brazil, prior to the introduction of vaccination against the disease, and to determine the positive and the negative predictive values of a history of varicella infection. In 2001, 589 inhabitants of two Kuikuro villages and three Kaiabi villages were evaluated and provided information concerning previous varicella infection. An indirect immunosorbent assay (ELISA) to detect IgG anti-VZV antibodies was performed in 224 blood samples - volunteer selection had no interference of anamnesis. IgG prevalence was 80.8% (95% Confidence Interval: 76% - 86%). The seroepidemiology of varicella in Xingu National Park prior to varicella vaccine introduction was comparable to the Brazilian national seroprevalence described in the literature, and so were the positive (98%) and the negative predictive value (41%) of the referred history. |

Em 2001, 589 habitantes de duas aldeias Kuikuro e três aldeias Kaiabi foram avaliados e forneceram dados referentes à infecção prévia por varicela. Um ensaio imunoenzimático indireto (ELISA) foi realizado em 224 amostras de sangue para detectar anticorpos IgG anti-VVZ - a seleção de voluntários não teve interferência da anamnese. A prevalência de IgG foi de 80,8% (Intervalo de Confiança de 95%: 76% - 86%). A soroepidemiologia de varicela no Parque Nacional do Xingu antes da introdução da vacina foi comparável à soroprevalência nacional descrita na literatura, assim como os valores preditivos positivo (98%) e negativo (41%) da história referida.Federal University of São Paulo Division of Pediatric Infectious DiseasesUNIFESP, Division of Pediatric Infectious DiseasesSciELOInstituto de Medicina TropicalUniversidade Federal de São Paulo (UNIFESP)Lafer, Manuel Mindlin [UNIFESP]De Moraes-Pinto, Maria Isabel [UNIFESP]Weckx, Lily Yin [UNIFESP]2015-06-14T13:31:37Z2015-06-14T13:31:37Z2005-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion139-142application/pdfhttp://dx.doi.org/10.1590/S0036-46652005000300004Revista do Instituto de Medicina Tropical de São Paulo.
