Abstract
Human papillomavirus infection (HPV) is a significant global public health concern, known to be a leading cause of cancer related death among women in sub-Saharan Africa. This study assessed knowledge of HPV infection, transmission, prevention, and HPV vaccine uptake among tertiary institution students in Plateau State, Nigeria. A cross-sectional study was conducted among students from two tertiary institutions in Plateau State, Nigeria. Using a structured pretested questionnaire, data were collected from participants selected by two-stage sampling technique. Participants' responses were analysed to assess their knowledge regarding HPV transmission, prevention, and vaccination. A composite score was obtained for the general HPV knowledge. A score of more than 70.0% indicated good knowledge. The distribution of the variables was examined using frequency distribution and descriptive statistics. The chi-square test was performed for bivariate analysis. Logistics regression was performed to examine the odds of having good HPV knowledge among the students. Level of significant was set at 95%. Of the 425 participants, 302 (71.1%) were female and 123 (28.9%) were male, with a mean age of 23 ± 2.8 years. There was low awareness of HPV among participants, with higher awareness among the females 66 (23.1%) than the males 26 (22.2%) (p = .853). Both female 77 (26.1%) and male participants 31 (26.72%) had low awareness of HPV vaccination. Among all participants, only 19 (5%) demonstrated good knowledge of HPV. Participants who were employed significantly had good knowledge of HPV compared to those who were unemployed. There was inadequate general knowledge of HPV and its vaccination among tertiary institution students in Plateau State, Nigeria. The students' employment status was associated with their knowledge of HPV. Targeted educational programs focusing on diverse educational levels and institution types are recommended to enhance HPV knowledge and promote vaccine uptake.

Abstract
BACKGROUND The expected corresponding increase in tonsillar human papillomavirus (HPV) infection associated with increasing incidence of oropharyngeal squamous cell carcinoma (OPSCC) substantiate the evaluation of normal tonsillar tissue in different population. The epidemiology of HPV in tonsillar tissue varies geographically. This study evaluated samples from two countries to determine the prevalence in respective samples. OBJECTIVE To characterize HPV infection in non-malignant tonsillar tissue from Shaanxi, China (herein after referred to as China) and Punjab, Pakistan (herein after referred to as Pakistan). METHODOLOGY The DNA extracted from formalin-fixed, paraffin-embedded tumor free tonsillar tissue was evaluated using polymerase chain reaction (PCR). A total of 367 cases from China and 139 cases from Pakistan were screened for HPV DNA using GP5+/GP6+ consensus primer. Genotype of the positive cases was determined for common HPV types (6, 11, 16, 18, 52, 58) simultaneously by type-specific PCR. RESULTS The mean age of cohorts in China was 13.42 (Median age 7, Range 2-72 years) while in Pakistan it was 10.77 (Median age 8, Range 3-42 years) the gender distribution was 61.6% male in China and in Pakistan they were 56.8%, rest were females. The overall prevalence of HPV in China was 2.45% and 2.16% in Pakistan. High risk human papillomavirus was 1.63% in China with 5 cases positive for HPV 16 and HPV 58 in 1 case. In Pakistan, 2 cases (1.43%) of HPV 16 were detected. Low-risk types include HPV 11 present in 2 cases from China, while HPV 6 was detected in 1 case each from both the countries. CONCLUSION A low prevalence of HPV was found in China and Pakistan; high-risk and low-risk HPV were detectable in tonsillar tissue from both countries. Age stratification (< 5 years, 5-14 years, 15-25 years, > 25 years) suggest that sexual and non-sexual transmission of the virus can occur. The difference in the genotype distribution geographically within China and with Pakistan was observed in the case of HPV 58. The most common type in both the countries was HPV 16.

Abstract
Waterborne exposure to human viruses is possible through contact with contaminated water environments and can result in infections associated with a wide range of illnesses, including gastrointestinal, respiratory, ear, ocular, and skin infections. Recently, the occurrence in water environments of two groups of human viruses-both known with oncogenic potential, human polyomaviruses (HPyVs) and papillomaviruses (HPVs)-has been reported worldwide. These viruses, responsible for highly prevalent infections worldwide, have recently been proposed as potentially emerging waterborne pathogens. The objective of the present study was to examine the occurrence of HPyVs and HPVs in surface waters, by monitoring two rivers in Northwestern Italy, by nested PCR assays and sequencing. HPyVs (JC, BK, and Merkel cell polyomavirus) were detected in 10/25 (40%) samples. HPVs (HPV8, 17, 21, 25, 32, 80, 99, 105, and putative new HPVs) were identified in 14/25 (56%) river samples. The number of HPV DNA copies in waters was measured by quantitative real-time PCR. To our knowledge, this is the first detection and quantification of HPVs in surface waters. The possibility that HPyVs and HPVs can be transmitted by the waterborne route deserves to be explored in future studies.

Abstract
AIMS Viral outbreaks associated with swimming pools have been described worldwide. The objective of this study was to examine the extent of viral contamination in indoor and outdoor swimming pools. METHODS AND RESULTS Pools were examined for the presence of human enteric viruses (adenovirus, norovirus and enterovirus) and nonenteric viruses (papillomavirus and polyomavirus-BK, JC, KI, WU and Merkel cell). Bacteriological parameters were also evaluated. The analysed pool waters met microbiological quality standards. Enteric viruses were not detected. On the other hand, papillomaviruses (HPV8, 12, 23, 25, 120 and unclassified HPVs) and polyomaviruses (JC and Merkel cell polyomaviruses) were detected in 9/14 samples (64%). The number of HPV DNA copies in pool waters, measured by quantitative Real-time PCR, ranged from 1.27E+04 to 1.13E+05/10L. CONCLUSION Results show that a variety of nonenteric viruses may be discharged in pool waters by various secretions and excretions from infected individuals or asymptomatic carriers. SIGNIFICANCE AND IMPACT OF THE STUDY To the best of our knowledge, this is the first report on human papillomaviruses and polyomaviruses in swimming pools. The likelihood that these viruses can be transmitted by recreational activities deserves to be explored in future studies.

Abstract
Objective Much controversy still exists about maternal-to-infant transmission of human papillomavirus (HPV) infection, specifically about the magnitude of the risk and the route and timing of such vertical transmission. This prospective cohort study examines the risk of vertical transmission of maternal HPV in each trimester of pregnancy. Study design One hundred fifty three healthy pregnant women were followed longitudinally throughout pregnancy and cervical swabs obtained in each trimester and postpartum for HPV detection. Cord blood, neonatal nasopharyngeal aspirates, and placental biopsies were collected at delivery. DNA isolation, polymerase chain reaction, and hybridization were performed using the GG HPV Genotyping Chip Kit (Goodgene Inc., Seoul, Korea). Detection of HPV in neonates was defined as the presence of HPV DNA in either cord blood or neonatal nasopharyngeal aspirate. Results HPV DNA was detected in 14%(22/153) of healthy women in the first trimester, 18%(22/124) in the second trimester, and 10%(15/153) in the third trimester; 24%(37/153) were positive for HPV DNA on at least one occasion in pregnancy. At birth, 5.2%(8/153) of neonates were HPV DNA positive. Seven of these eight infants were born to HPV-positive mothers. Placental HPV DNA was positive in 3.3%(5/152) of cases, and all five cases were from mothers with at least one HPV-positive test. Detection of HPV DNA in neonates was associated with detection of HPV in mothers during any of the three trimesters of pregnancy. Conclusion HPV DNA was detected at birth in 5.2%(8/153) of neonates born to healthy women, and was associated with the detection of HPV in mothers during any of the three trimesters of pregnancy.

Abstract
OBJECTIVES To elucidate the concordance of human papillomavirus (HPV) genotypes between the mother and her newborn and to identify risk factors for the vertical transmission of HPV. STUDY DESIGN HPV genotypes present in 329 pregnant women, their newborns, cord blood, and placenta samples were determined by molecular techniques, including using pure DNA for nested polymerase chain reaction. HPV antibodies were tested using multiplex HPV serology. Kappa statistics and the Wilcoxon test were used to assess concordance, and regression analysis was used to calculate ORs and 95% CIs. RESULTS HPV DNA was detected in 17.9% of oral samples from newborns and in 16.4% of the cervical samples of the mothers. At delivery, mother-newborn pairs had similar HPV-genotype profiles, but this concordance disappeared in 2 months. Oral HPV carriage in newborns was most significantly associated with the detection of HPV in the placenta (OR=14.0; 95% CI, 3.7-52.2; P=.0001). The association between status of the cord blood and oral HPV was also significant at delivery (OR=4.7; 95% CI, 1.4-15.9; P=.015) but disappeared within 1 month. HPV antibodies in infants were of maternal origin (OR=68; 95% CI, 20.1-230.9; P=.0001). CONCLUSIONS HPV is prevalent in oral samples from newborns. The genotype profile of newborns was more restricted than that of the maternal cervical samples. The close maternal-newborn concordance could indicate that an infected mother transmits HPV to her newborn via the placenta or cord blood.

Abstract
Several viruses can pass the maternal-fetal barrier, and cause diseases of the fetus or the newborn. Recently, however, it became obvious, that viruses may invade fetal cells and organs through different routes without acute consequences. Spermatozoa, seminal fluid and lymphocytes in the sperm may transfer viruses into the human zygotes. Viruses were shown to be integrated into human chromosomes and transferred into fetal tissues. The regular maternal-fetal transport of maternal cells has also been discovered. This transport might implicate that lymphotropic viruses can be released into the fetal organs following cellular invasion. It has been shown that many viruses may replicate in human trophoblasts and syncytiotrophoblast cells thus passing the barrier of the maternal-fetal interface. The transport of viral immunocomplexes had also been suggested, and the possibility has been put forward that even anti-idiotypes mimicking viral epitopes might be transferred by natural mechanisms into the fetal plasma, in spite of the selective mechanisms of apical to basolateral transcytosis in syncytiotrophoblast and basolateral to apical transcytosis in fetal capillary endothelium. The mechanisms of maternal-fetal transcytosis seem to be different of those observed in differentiated cells and tissue cultures. Membrane fusion and lipid rafts of high cholesterol content are probably the main requirements of fetal transcytosis. The long term presence of viruses in fetal tissues and their interactions with the fetal immune system might result in post partum consequences as far as increased risk of the development of malignancies and chronic pathologic conditions are discussed.

Abstract
BACKGROUND This study is aimed to clarify data on the acquisition, persistence, and clearance of high-risk types of human papillomavirus (HPV) DNA from the mucosa and the determinants of persistent mucosal HPV infection in infants. METHODS Oral and genital scrapings from 324 infants were collected at birth, 3 days after delivery, and 1, 2, 6, 12, 24, and 36 months after delivery and tested for the presence of HPV DNA by nested polymerase chain reaction and hybridization with 12 high-risk HPV oligoprobes. HPV status and demographic data for parents were analyzed. RESULTS During the follow-up period (median duration, 26.2 months), HPV DNA was found to be present in 12%-21% of oral scrape samples and in 4%-15% of genital scrape samples obtained from the infants. Oral HPV infection was acquired by 42% of children, cleared by 11%, and persisted in 10% of the infants, whereas 37% were never infected. The corresponding figures for genital HPV infection were 36%, 14%, 1.5%, and 47%. Kaplan-Meier analysis revealed that both the cumulative incidence of infection and clearance of HPV were parallel in oral and genital sites. Persistent oral HPV infection in the child was significantly associated with persistent oral HPV infection in the mother at month 36 of follow-up, hand warts in the mother, young age at onset of sexual activity for the mother, and the mother's use of oral contraception, as well as with the father's oral HPV status at 24 months. Persistent genital HPV infection in the infant was predicted by if the mother had started smoking at 18-21 years of age and by a history of genital warts. CONCLUSIONS Persistent carriage of high-risk HPV types was detected in oral and genital mucosa specimens obtained from 10% and 1.5% of the infants during their first 26 months of life. The rates of acquisition and clearance of HPV were similar in oral and genital mucosa.
