Abstract:
Objective In order to evaluate the distribution of genetic subtypes and epidemiological feature of HIV-1 circulating strains in Fujian province. Methods Blood samples and epidemiological data were collected from 104 newly infected patients who were distinguished by BED-CEIA methodology,during 2011-2012. Viral sequences (n=81) of HIV-1 gag,env,and pol segments were amplified by nested PCR. Results Subtypes B and four Circulating Recombinant Forms,(CRF01_AE,CRF07_BC,CRF08_BC and CRF55_01B) were found in the samples, CRF01_AE(45.68%)and CRF07_BC(35.80%)were the two main HIV-1 strains in Fujian province. Compared with previous data,the proportion of CRF07_BC rose significantly while it gradually decreased in CRF01_AE. Heterosexual contact was still the principal transmission route in Fujian province, but the number of infection among men-who-have-sex-with- men grew rapidly. Conclusion Results from this study suggested that different subtypes of HIV-1 strain existed in Fujian province. The distribution of subtypes and the mode of transmission were changing with the progress of epidemic. Dynamic monitoring of the molecular epidemiology trends of HIV-1 infection should be enhanced.
