“…Regarding species 7, HPV-18 was the second most prevalent type in single infections, whereas HPV-45 was found only in multiple infections. These results agree with those of previous reports showing that genotypes belonging to this species are more often present in multiple infections than in single infections [15].…”

The prevalence of human papillomavirus (HPV) infections in 2109 females inhabiting five cities of Colombia was determined. Of the 49.2% with an HPV infection, 59.8% were infected with more than one viral type. Species 7 (of the the genus Alphapapillomavirus) was associated with multiple infections. Analysis of the socio-demographic data revealed a statistically significant protective effect associated with the status of civil union (civil recognition of cohabitation without marriage), and indigenous ethnicity proved to be a risk factor for HPV infection. This is the first study comparing HPV infection among women from geographical regions of Colombia with different socio-cultural structures.

“…In some countries, HPV co-infection is less frequent than the mono-infection, [21, 22] but others have a higher co-infection prevalence [13]. In Mexico the prevalence and patterns of co-infection differ according to the geographic location analyzed [23, 24].…”

BackgroundHuman papillomavirus (HPV) is associated with the genesis of cervical carcinoma. The co-infection among HPV genotypes is frequent, but the clinical significance is controversial; in Mexico, the prevalence and pattern of co-infection differ depending on the geographic area of study. We analyzed the mono- and co-infection prevalence of multiple HPV genotypes, as well as preferential interactions among them in a Mexico City sample population.MethodsThis study was designed as a retrospective cohort study. Cervical cytology samples from 1163 women and 166 urethral scraping samples of men were analyzed between 2010 and 2012. The detection of HPV infection was performed using the hybrid capture and the genotyping was by PCR (HPV 6, 11, 16, 18, 30, 31, 33, 35, 45, 51, and 52).Results36% of women were HPV-positive and the most prevalent genotypes were HPV 51, 52, 16, and 33 (42, 38, 37, and 34%, respectively). The prevalence of co-infection was higher (75.37%) than mono-infection in women HPV positives. All genotypes were co-infected with HPV 16, but the co-infection with 51–52 genotypes was the most frequent combination in all cases.ConclusionThe co-infection was very common; each HPV genotype showed different preferences for co-infection with other genotypes, HPV 51–52 co-infection was the most frequent. The HPV 16, 33, 51 and 52 were the most prevalent and are a public health concern to the Mexican population.Electronic supplementary materialThe online version of this article (doi:10.1186/s12885-017-3519-7) contains supplementary material, which is available to authorized users.

“…Estudo realizado nos EUA relatou uma alta frequên-cia de HR-HPV entre mulheres com idade de 20-29 anos 21 , consistente com outro que encontrou 85% de positividade para HPV composto por genótipos de alto risco oncogênico em mulheres jovens. 22 Esta prevalência é atribuída à maior exposição aos fatores de risco que está faixa está está sujeita e que favorecem a aquisição viral. 23,24,25 A infecção por múltiplos tipos de HPV foi detectada em 35% das amostras positivas, com associação significativa entre a detecção de genótipos HR-HPV (p ≤ 0,05).…”

Study design: cross. Study objective: estimate the frequency and distribution types of human papillomavirus (HPV) in sexually active young women. Methods: samples of vaginal and endocervical canal of 158 women, aged between 18 and 35 years were collected through self-collection technique. The HPV DNA was extracted and amplified by PCR end point using the consensus primers PGMY09/11 and genotyping was performed by PCR specific type (TS-PCR) and by analysis of the fragments obtained from the use of restriction enzymes (RFLP). Results: HPV DNA was detected in 23% of participants, 92% were high-risk HPV genotypes (HR), being the prevalent HPV45, followed by HPV16 and 31 infections with multiple HPV types were detected in 35% of samples, indicating infection by more than two types in 22.2% of the genotyped. Higher frequency of HPV DNA was detected in women ≤ 25 old. Conclusion: this demonstrated a high frequency of HPV infection in sexually active young women, as well as a high prevalence of infection with multiple types of high oncogenic risk.
