Objective:To comprehend the status of infection as well as distribution of types of Human papillomaviruses(HPV) and provide evidence for diagnosis and prevention.Methods:665 samples were detected and genotyped with the technology of gene chips.The data was analyzed with the statistical software SPSS13.0.Results:①37.65% of those samples were detected positive for HPV infection and 20 HPV genotypes were detected successfully.Among them

27.25% were infected by single HPV genotype

7.22% were infected by two genotypes and 3.18% were infected by three genotypes.In the single infection of HPV

the percentages of 16

and the rate of others of other genotypes were 3.29%.②The rates of different age group of high risk HPV were 14.1%(≤20)

15.2%(21～30)

17.2%(31～40)

17.3%(>40)(χ2=3.0

P>0.05).The rates of different age group of low risk HPV were 20.3%(≤20)

11.7%(21～30)

10.1%(31～40)

10.1%(>40)(χ2=23.28

P<0.01)

a statistically significant difference between the groups.Conclusion:①In the area of Sichuan

HPV infection situation was comparatively severe and most were single infection.Among the high risk HPV infections

HPV16 prevalence was highest

and among the low risk HPV infections

types 6 and 11 were the most prevalent.②Age had certain something to do with HPV infection.③The present study palyed an important role in preventing and treating the diseases caused by HPV

such as cervical cancer

condylomata acuminate.
