PubMed Central. The Chinese Honghe Autonomous Prefecture Honghe in Yunnan Province is a unique ethnic area because it is inhabited by more than ten different minority ethnic groups. Geographically, Honghe directly shares a border with Vietnam. The objective of this study was to investigate genetic diversity and distribution of the Hepatitis C virus HCV in Honghe.
The viral diversity and origins of dissemination were examined by phylogenetic analyses. Three HCV genotypes 1, 3 and 6 with six subtypes 1b, 3b, 3a, 6a, 6n and 6v were identified. The most predominant form was genotype 3 The HCV subtype 3b appeared to be the most frequent form Further phylogenetic analyses suggested that similar HCV-6a viruses might have been circulating in the Honghe area for more than a decade, which likely originated from Vietnam or vice versa.
Information presented here should provide useful information for future health surveillance and prevention of HCV infection in this area.
Babesia, usually found in wild and domestic mammals worldwide, have recently been responsible for emerging malaria-like zoonosis in infected patients. Human B. In this region, a diverse topographic range combined with tropical moisture sustains a high biodiversity of small mammals, which might play important role on Babesia transmission. Small mammals were captured in sample locations from 18 counties located Yunnan Province, and screened for B. Univariate and multivariate forward stepwise logistic regression analysis was used to access the association between infections and some related risk factors.
Infection with Babesia microti was confirmed in 2. Significant differences in prevalence rates of B. Furthermore, adult small mammals had higher prevalence rates than younger, pubertal mammals.
