Epidemiological analysis and risk analysis of enterovirus C in the Philippines

人类肠道病毒（HEV）分为四种（HEV- a、B、C和D）。HEV-C的流行病学仍然广泛未知。我们对菲律宾17年脊髓灰质炎监测期间从急性弛缓性麻痹病例中分离出来的非脊髓灰质炎肠病毒进行了分型。结果，790株非脊髓灰质炎肠道病毒中有108株被分型为HEV-C。此外，在这项研究中发现的一种HEV-C被证明与2001年在瘫痪病例中发现的病毒密切相关。此外，从菲律宾城市和农村地区收集的河水样本中检测到HEV-C。

Human enteroviruses (HEV) are classified into four species (HEV-A, B, C, and D). Epidemiology of HEV-C is still widely unknown. We typed non-polio enteroviruses, which had been isolated from acute flaccid paralysis cases during 17 years of polio surveillance in the Philippines. As results, 108 strains among a total of 790 non-polio enteroviruses were typed as HEV-C. Also one of HEV-C identified in this study was shown to be closely related to the virus detected in paralysis cases in 2001. Furthermore, HEV-C was detected from river water samples collected in urban and ruralareas in the Philippines.
