Abstract: Objective:To investigate the infection rate and intra-type lineage distribution of human papillomavirus type 30 (HPV30) in Chinese women.Methods:Cervical exfoliated cells were collected within 30 days of cytological tests for patients from the People’s Liberation Army General Hospital. After DNA extraction and screening of HPV30 type specific polymerase chain reaction (PCR), full-length genomes were amplified for HPV30 positive samples.Results:A total of 1 600 cervical samples were collected. The infection rate of HPV30 was 0.56% (9/1 600). All the nine HPV30 strains belonged to lineage A. A1 accounted for 66.7%(6/9), A4 accounted for 22.2%(2/9), A5 accounted for 11.1%(1/9).Conclusion:HPV30 infection exists among Chinese women. Lineage A was the only prevalent lineage across all the HPV30 isolates.
