For this study, 50 HIV-1 plasma samples of recently infected men who have sex with men (MSM) were amplified and sequenced. Multiple subtypes were identified by phylogenetic analyses of HIV-1 gag, env, and pol gene regions, including CRF01_AE (56.0%), CRF07_BC (30.0%), subtype B (12.0%), and unique recombinant forms (URFs, 6.0%). CRF01_AE was the most(More)
BACKGROUND There has been a clear increase in HIV-1 infection cases in recent years in Hebei Province, China, and transmission via blood is one of the risk factors in the early. This article aimed to investigate the HIV infection rate and control efficiency among the paid blood donor population over a period of 18 years. METHODS From 1995-2013, HIV/AIDS(More)
OBJECTIVE To investigate the effect of highly active anti-retroviral therapy (HAART) on reducing HIV/AIDS related death. METHODS The analysis was conducted by using the data of 4,148 HIV/AIDS cases reported in Hebei province from 1989 to 2013. Regular follow-up, CD4 detection, registration of death were carried out for them. Free HAART has been provided(More)
BACKGROUND Since the first HIV-1 case in 1989, Hebei province has presented a clearly rising trend of HIV-1 prevalence, and HIV-1 genetic diversity has become the vital barrier to HIV prevention and control in this area. To obtain detailed information of HIV-1 spread in different populations and in different areas of Hebei, a cross-sectional HIV-1 molecular(More)
Neisseria meningitidis is a major public health concern worldwide, including China. A few cases of serogroup W meningococcal disease have been reported in southeast China in recent years. Thus far, invasive disease due to W isolates has involved sequence type 11. We report two cases of N. meningitidis infection caused by CC4821 serogroup W strains.
We found cluster 1 and cluster 2 that were identified as two potential circulating recombinant forms (CRFs) by analyzing the recombinant breakpoints and phylogenetic tree. Three sequences composed of CRF01_AE, subtype C, and potential subtype B (N/A) in cluster 1 had nearly identical recombinant breakpoints, and four sequences composed of CRF01_AE and(More)
Sexual exposure has been the predominant route of HIV-1 spread in Hebei Province, China. However, little information is available on HIV-1-transmitted drug resistance (TDR) among HIV-1-infected youths aged 16 to 25 years who are infected with HIV-1 and sexually active. In this study, the overall prevalence of TDR was 6.6% (10/152), a moderate level(More)
BACKGROUND To understand HIV-1 drug resistance in 11 prefectures of Hebei Province, China, we implemented a cross-sectional HIV-1 molecular epidemiological survey. METHODS Blood samples were collected from 122 newly diagnosed drug-naïve HIV-1-positive individuals and 229 antiretroviral therapy (ART)-failure individuals from 11 prefectures in Hebei(More)
HIV-1 genetic diversity has recently been more and more complicated in Hebei province. To know about the transmission pattern of HIV-1 in Hebei, the phylogenetic analysis of non-CRF01_AE strains was performed using the maximum-likelihood (ML) method. Four clusters and two clusters were observed in the CRF07_BC and subtype B ML tree, respectively. Of these(More)
New human immunodeficiency virus type 1 (HIV-1) diagnoses are increasing rapidly in Hebei. The aim of this study presents the most extensive HIV-1 molecular epidemiology investigation in Hebei province in China thus far. We have carried out the most extensive systematic cross-sectional study based on newly diagnosed HIV-1 positive individuals in 2013, and(More)
