Hubei Province is a major epidemic area of severe fever with thrombocytopenia syndrome bunyavirus (SFTSV) in China. However, to date, a few SFTSV strains have been isolated from Hubei Province, preventing effective studies of epidemic outbreaks. Here, we report three confirmed patients (2015-2016) ..., Abstract

The dengue virus (DENV) is a vital global public health issue. The 2014 dengue epidemic in Guangzhou, China, caused approximately 40,000 cases of infection and five deaths. We carried out a comprehensive investigation aimed at identifying the transmission sources in this dengue epidemic. To analyze ..., Abstract

Recent outbreaks of Zika virus (ZIKV) infections in Oceania's islands and the Americas were characterized by high numbers of cases and the spread of the virus to new areas. To better understand the origin of ZIKV, its epidemic history was reviewed. Although the available records and information ..., Abstract

To investigate molecular epidemiology of DuCV in Cherry Valley ducks in China, the complete genomes of six DuCV strains, which were detected from Cherry Valley ducks in China between 2007 and 2008, were sequenced. Sequence and phylogenetic analysis were carried out to compare these six strains with ..., Abstract

A total of 100 H1N1 flu real-time-PCR positive throat swabs collected from fever patients in Zhejiang, Hubei and Guangdong between June and November 2009, were provided by local CDC laboratories. After MDCK cell culture, 57 Influenza A Pandemic (H1N1) viruses were isolated and submitted for whole ..., Abstract

Banana streak virus (BSV), a member of genus Badnavirus, is a causal agent of banana streak disease throughout the world. The genetic diversity of BSVs from different regions of banana plantations has previously been investigated, but there are relatively few reports of the genetic characteristic ..., Abstract

Duck circovirus (DuCV), a potential immunosuppressive virus, was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction (PCR) based method. In this study, a total of 138 sick or dead duck samples from 18 different farms were examined with an average ..., Abstract

Southern rice black-streaked dwarf virus (SRBSDV) is a novel Fijivirus prevalent in rice in southern and central China, and northern Vietnam. Its genome has 10 segments of double-stranded RNA named S1 to S10 according to their size. An isolate of SRBSDV, JNi4, was obtained from naturally infected ..., Abstract

In this study, we determined the complete nucleotide and deduced amino acid sequence of a primary isolate of rabies virus (SH06) obtained from the brain of a rabid dog. The overall length of the genome was 11 924 nucleotides. Comparison of the genomic sequence showed the homology of SH06 at ..., Abstract

Porcine reproductive and respiratory syndrome virus (PRRSV) has been recognized as one of the most important pathogens of pigs throughout the world. In 2006, more than 10 provinces of China have experienced an epizootic outbreak of pig diseases characterized by high fever, reddened skin and high ..., Abstract

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. ..., Abstract

Illegally paid blood donation was a risk factor for HIV acquisition exclusively in Henan and Hubei Provinces of China, and not in Shanghai. Nucleotide sequences in the gag and env genes of HIV-1 were compared between isolates from Henan and Shanghai regions of China to test whether an expected ..., Abstract

Respiratory syncytial virus(RSV) was isolated from nasopharyngeal aspirates(NPA) collected of children suffering acute lower respiratory tract infection in the Children’s hospital of Zhejiang province in the winter of 2004. The isolated strains were identified by RT-PCR. The whole region of the G ..., Abstract

In order to analyze the gene characterization of Human immunodeficiency virus-1(HIV-1) prevalence in Henan Province, a HIV-1 strain, named CNHN24, was isolated from one HIV-1 infected blood donor. The proviral DNA was extracted from productively infected PBMCs (peripheral blood mononuclear cells) ..., Abstract
