ABSTRACT
Objective To evaluate the infection status and genotype distribution of high risk human papillomavirus (HPV) in Chongqing women with different healthy status of cervix .Methods A retrospective analysis including 3 118 cases from June 2013 to March 2014 were performed ,945 of which were carried out multiplex real time PCR ,and data of cervix healthy status and HPV positive cases were subjected to chi‐square test .Results The general positive percentage of high risk HPV was 27 .49% ,16 .35%in healthy check‐up group ,and 24 .42% in cervicitis group and 39 .87% in cervical neoplasia lesion ,there was a significant difference of HPV positive ratio between these three groups(P< 0 .05) ;and HPV positive ratio was higher in older women without significant difference .In Chongqing region ,the three most common HPV types were HPV52 (21 .97% ) ,HPV16 (20 .00% ) and HPV58 (14 .75% ) .However ,the three most common HPV types in various groups are different :HPV52 (26 .20% ) ,HPV58 (14 .3% ) and HPV51 (10 .70% ) in health check‐up group ; HPV52 (21 .10% ) ,HPV58 (20 .00% ) and HPV16 (18 .90% ) in cervicitis group while HPV16 (29 .00% ) ,HPV52 (19 .80% ) and HPV58 (11 .50% ) in cervical neoplasia lesion group .The multiple infec‐tion rate of HPV was 5 .86% ,as the cervix status gets worse ,HPV concurrent infection increases ,and concurrent HPV types vary :mostly with HPV 52 in healthy check‐up group while with HPV 16 in cervical neoplasia lesion group .Conclusion The prevalence and genotype distribution of HPV in Chongqing women with different healthy status of cervix are significant difference.
