“…In the past, polioviruses were detected in meningitis cases and Echo 9 was responsible for an outbreak of meningitis that occurred in São Paulo (SP) and Rio de Janeiro (RJ) in 1967and 1978, respectively (Godoy et al 1967, Nery-Guimarães et al 1981. Other serotypes of Echo were found together with coxsackievirus B, EV 71 and no typed EV in cases of meningitis that occurred in three different Brazilian cities: Rio de Janeiro, RJ, Belém, state of Pará (PA) and Salvador, state of Bahia (BA) (Bedoya et al 1998, Gomes et al 2001, Ferreira et al 2002, Silva et al 2002, Lamarão et al 2005, Gomes et al 2007). In Brazil, Echo 30 has been associated with outbreaks and with frequent and sporadic cases of meningitis.…”

“…[1][2][3][4][5] No Brasil, os enterovírus também são os principais responsáveis pela meningite viral. 6 O comportamento epidêmico não é só observado no Recife, senão também em outras cidades brasileiras 7,[16][17][18][19][20] e países do mundo, 3,5,[8][9][10][11][12] incluindo os mais desenvolvidos. As duas epidemias detectadas foram diferentes, tanto no que se refere à magnitude quanto no delineamento das curvas.…”

“…6,7,17 A segunda epidemia, cujo agente causal não foi identificado, apresentou maior número de casos que a anterior e risco de adoecimento 7,66 vezes maior do que no período endêmico correspondente. Nas duas epidemias, os casos ocorreram em todas as regiões da cidade, com maior quantidade de bairros atingidos e maior frequência de casos por bairro, em relação aos períodos endêmicos.…”

“…2 A doença atinge todas as faixas etárias, embora as crianças sejam mais susceptíveis, e geralmente evolui clinicamente de forma aguda e benigna. [1][2][3][4][5][6][7] Não obstante, a doença desperta grande atenção não só dos médicos, pela necessidade de diagnóstico diferencial com as formas bacterianas, como também dos familiares do caso, pois a associação das meningites ao risco elevado de transmissão e morte compõe a representação social da doença. 1,4 Muitos tipos de vírus causam essa forma de meningite.…”

“…Of all cases of viral aseptic meningitis in children, echovirus accounts for 80-90% [3] while E-30 is one of the most frequently isolated HEVs in aseptic meningitis (AM) cases. Recent increases in E-30 activity associated with recurrent epidemics of AM have been reported worldwide in the past two decades, e.g., Taiwan [4,5], Japan [6], China [7], US [8,9], Brazil [10], Spain [11], Germany [12], France [13][14][15], the European continent [8,16], and Russia, New Independent States [17].…”

To investigate the molecular epidemiology of Taiwanese Echovirus 30 (E-30) strains, we analyzed the 876 bp sequence of the VP1 gene from 32 Taiwanese strains isolated in 1988-2008, 498 reference sequences, and one Echovirus 21 strain as the out-group. Phylogenetic analysis detected six E-30 genotypes (designated GI-GVI) that had circulated globally during the past five decades. The genotypes varied widely in geographic distribution and circulation half-life. The GI, GII, and GV were ancient genotypes in which the first strains emerged in the 1950s. The GIII was a reemerging genotype, in which strains had first appeared in Colombia in 1995 before reemerging in the New Independent States (NIS) in 2003. The GIV, an emerging genotype that recently appeared in Asia in 2003, was closely related to the ancient genotypes. The GVI was the circulating genotype, which included eight clusters (A-H) that had circulated since 1967. No GVI-A, C, D, or E strains have been identified during the past 10 years. The GVI-B first appeared in China in 1984 and later in Russia and Asia in the 2000s. The GVI-F, G, and H strains, which comprised the prevalent clusters, had been dominant in Asia Pacific area, globally, and Europe, respectively. Taiwanese strains were classified into GVI-D (1988-1989), GVI-F (1993-2004), and GVI-G (1993-2008). The quiescence period of E-30 is longer in Taiwan (5-8 years) than in other countries (3-5 years).
