Abstract
OBJECTIVES Human papillomavirus (HPV) infection is closely associated with cervical cancer, especially the persistent infection of high-risk HPV (HR-HPV) genotypes. Therefore, investigating the HPV prevalence, age-specific, genotype distribution and the impact of the COVID-19 pandemic among large populations was essential for HPV screening and optimising vaccination. DESIGN This was a cross-sectional study. METHODS A total of 38 056 cervical epithelial cell specimens were collected in Weifang city from January 2018 to December 2022. The study was divided into seven age groups based on the age of the participants. HPV genotype testing was performed by using a commercial kit which is designed for the detection of 23 HPV genotypes. RESULT A total of 8998 women were infected with HPV, with an overall positive rate of 23.64% (8998/38 056). Single infection of HPV was dominant among different age groups, which accounted for 71.33% of total infections. The most prevalent genotype was HR-HPV 16 (4.33%), followed by 52, 58, 53 and 68. Low-risk HPV (LR-HPV) 42 exhibited the highest prevalence (2.19%) among six LR-HPV genotypes, representing a novel finding. There was a significant difference in the prevalence across different age groups (p<0.01), with the highest prevalence in the group under 25 years old. During the 3 year COVID-19 breakout period, the number of HPV samples received in 2020, 2021 and 2022 was reduced by 24.03%, 14.79% and 24.76%, respectively. In 2018-2022, the annual prevalence varied between 21.09% and 25.30%, with a decreasing trend, while the prevalence of HR-HPV 39, 56, 31 and LR-HPV 42 increased. CONCLUSION This study indicates a high-HPV infection rate and age-specific distribution characteristics of HPV genotype infections, as well as analyses of the impact of the COVID-19 outbreak on the HPV prevalence, which provides an epidemiological basis for the control and prevention of HPV infection in this region.

Absolute Risk and Attributable Fraction of Type-Specific Human Papillomavirus in Cervical Cancer and Precancerous Lesions-A Population-Based Study of 6286 Women in Rural Areas of China. J Clin Med 2022; 11:jcm11216483. [PMID: 36362711 PMCID: PMC9655002 DOI: 10.3390/jcm11216483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/24/2022] [Accepted: 10/26/2022] [Indexed: 11/06/2022] Open
Abstract
Background: To investigate the human papillomavirus (HPV) genotype distribution among the general population and assess the attribution of HPV genotypes targeted by vaccines to protect against cervical lesions theoretically. Methods: Cervical samples were collected from women aged 21 to 64 years old from Inner Mongolia and Shanxi Province in China who had not been vaccinated against HPV. HPV type-specific absolute risk (AR) to classified cervical lesions was calculated and then the attributable fraction (AF) was estimated, together with the combined contributions of the HPV types, targeted by four available HPV vaccines and five HPV vaccines in clinical trials in China to protect against cervical lesions. Results: A total of 6286 women with an average age of 44.1 years ± 8.41 (range: 21−64) participated in the study. The age distribution of 14 HR-HPV and HPV16/18 all showed a ‘U’ shape, which peaked in the ≤25 year-group and >55 year-group. The five most common genotypes were HPV16 (4.3%), HPV52 (4.1%), HPV58 (2.1%), HPV51 (2.1%), and HPV66 (1.7%). The prevalence of HPV types 6 and 11 infections was 1.1% and observed with n significant differences across age stratifications in China. AF to CIN2+ was predominated by HPV 16 with 56.2%, followed by HPV58 (12.0%), HPV52 (8.5%), HPV18 (4.3%), and HPV51 (2.9%). HPV52 and 58 in the prophylactic HPV vaccine would enhance the protection against CIN2+ by approximately 20%. Conclusions: Regarding multi-valent HPV vaccine development in China, the HPV types 16, 52, 58, and 18 should be given priority for their high prevalence at the population level, high AR, notable AF, and high relative risk to high-grade cervical lesions.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. METHODS In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. RESULTS The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p<0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16-24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p<0.05). CONCLUSIONS HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

Abstract
Background: Human papillomavirus (HPV) DNA detection in cervical samples is widely used to identify HPV infection; however, there is little detailed evaluation of the characteristics of HPV prevalence by repeated DNA detection in community populations. Methods: Beginning in 2014, a Papanicolaou (Pap) smear and HPV cotesting program was implemented among older women living in the Minhang district of Shanghai. This report uses information from 225,000 participants, who provided person-time data. Of these, 632 subjects had 3 repeated visits and at least one HPV DNA-positive result in the last 5 years. Results: All 16 genotypes of HPV displayed thrice, twice, and once positivity results in 3 repeated tests and differed by proportions among and within genotypes. HPV52 and 58 are the two most dominant genotypes in total and in thrice positive person-time. The thrice positive person-time exceeded 50% in each of HPV58-, 35-, 52-, 56-, 18-, 68-, 31-, and 16-infected women. The single positive person-time ratio ranged from 7.9% (HPV35) to 38.9% (HPV11). Age differed among and within genotypes in thrice, twice, and once positive women. The average age of HPV-free controls was 59.0 ± 7.2 yo, which is close to the median of average ages for thrice and twice positive women and is older than most average ages for once positive women. The percentages of negative results for intraepithelial lesion or malignancy (NILM) for thrice HPV52-, 58-, 16-, 56-, and 59-positive women were significantly lower than the percentage of NILM for HPV-free women. Conclusion: Thrice and/or twice HPV DNA positivity are common in HPV-infected women and tend to occur in older women.

Prevalence and genotype distribution of human papillomavirus in Zhengzhou, China, in 2016. Arch Virol 2020; 165:731-736. [PMID: 31907615 DOI: 10.1007/s00705-019-04515-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Accepted: 12/02/2019] [Indexed: 01/22/2023]
Abstract
In this study, the prevalence and genotype distribution of human papillomavirus (HPV) in 49,793 women aged 25-64 years were determined by fluorescent real-time polymerase chain reaction (PCR) assay. HPV was detected in 6,020 women, giving a prevalence of 12.09% (6020/49,793). Single and multiple infections accounted for 71.81% (4323/6020) and 28.19% (1697/6020) of total infections, respectively. The most commonly found genotypes were HPV52 (19.90%, 1198/6020) and HPV16 (19.17%, 1154/6020), followed by HPV58 (13.11%, 789/6020), HPV81 (10.10%, 608/6020) and HPV56 (9.00%, 542/6020). The prevalence of HPV increased with age and was highest in the 54- to 64-year-old age group. The genotypes covered by the nonavalent HPV vaccine accounted for 39.32% (2367/6020) and 22.81% (1373/6020) of the total monoinfections and polyinfections, respectively. This study indicates a high HPV infection rate in women in the city of Zhengzhou and a large percentage of women are infected with single or multiple high-risk HPV genotypes that cannot be prevented using the current nonavalent HPV vaccine. Vaccines incorporating more HPV genotypes and extended age coverage for the current nonavalent vaccine might be necessary to better prevent HPV-related cervical cancer.

Abstract
We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at ≤25 years, a decline with age and a second peak at ≥55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing.

Abstract
The distribution of human papillomaviruses (HPVs) must be understood for the control and prevention of cervical cancer. Community-based Papanicolaou and HPV DNA tests were performed on 41 578 women. The prevalences of HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 were assessed. In total, 10% women were infected/co-infected by these HPVs. The infection rate increased from 7.1% in women aged ⩽30 years to 10.4% in those aged 50–60 years, and then decreased slightly to 9.9% in those aged >60 years. The HPV 16 and 58 positivity rates were significantly higher among women with high-grade squamous intraepithelial lesions (HSILs) than among those with cervicitis/negativity for intraepithelial lesion or malignancy (NILM) or low-grade SILs (LSILs). The HPV 18, 52 and 68 infection rates were significantly lower in women with HSILs than in those with NILM or LSILs. The proportion of women infected by multiple HPV strains was higher among those with HSILs. The proportions of the five most common genotypes, HPV 16, 18, 33, 52 and 58, increased with the number of co-infecting strains. HPV 16 and 58 were the high-risk HPVs in the Shanghai community and should be the focus in HPV screening and vaccination.

Abstract
Background Human papillomaviruses (HPVs) are strongly associated with the development of cervical carcinoma, and the distribution of HPV genotypes varies regionally. Methods To investigate the distribution characteristics of different genotypes of HPV infection in women in Wuhan, China, a total of 13 775 patients were enrolled over 2 years. Results Of these, 2436 patients were infected with HPVs, and the total infection rate was 17.68%. The infection rate of high‐risk HPV (HR‐HPV) was significantly higher (13.96%) than that of single low‐risk HPV (LR‐HPV; 3.72%). Among the HR‐HPV infections, the most common genotype was HPV 52 with an infection rate of 4.23%, followed by HPVs 16, 58, 39, and 51. The most common LR‐HPV genotype was HPV 81, followed by HPVs 6, 11, and 44. Patients under the age of 25 years were found to have the highest HPV infection rate (P < .05). After the age range of 51‐55 years, a downward trend in total HPVs and HR‐HPVs was observed. The HPV infection rate for a single genotype was higher than that for multiple HPVs (P < .01), and the detection rates in summer and winter were significantly higher than those in spring and autumn. Conclusions The results demonstrate that the distribution characteristics of various HPV genotype infections are associated with region and age and may be related to season. These data could be the basis for further epidemiological analysis into the control and prevention of HPV infection in this region.

Abstract
Human papillomaviruses (HPV) infected men causes continued transmission of HPV to women. The prevalence of 15 high-risk HPV strains (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68) and 6 low-risk HPV strains (HPV6, 11, 42, 43, 44 and CP8304) were evaluated in 935 males with genital warts. Of the 447 (447/935, 47.8%) HPV DNA positive subjects, 230 (24.6%), 356 (38.1%) and 139 (14.9%) were infected by high-risk, low-risk and both high and low-risk HPV respectively. Of the 356 low-risk HPV infected subjects, 333(93.5%) were infected by single HPV strain; 203 (57.0%), 147 (41.3%), 24 (6.7%) and 5 (1.4%) were infected with HPV genotype 6, 11, CP8304 and 44 respectively; population with age ≤ 20 showed the highest infection rate. High-risk HPV are also highly prevalent in our patients, genotype 16, 58, 51, 39, 52 and 53 are the top five prevalent genotypes with infection rates of 27.4%, 18.7%, 14.3%, 13.9%, 12.6% and 12.6% respectively; only 68.3% subjects were sole infection; subjects with 41 ≤ age ≤ 50 showed the highest infection rate. Both high and low-risk HPV are highly prevalent in men with genital warts, its impact on women HPV control and prevention need further evaluation.

Abstract
We aimed to characterize the trends and projections of cancer mortalities in Yangpu, an industry restructuring district of Shanghai, China. With high-quality data from the death registration system, the authors analyzed the trends in cancer mortalities during 1974-2014 and their relationship with pollution control and socioeconomic improvements. Cancer burden was projected into 2029. During 1974-2014, cancer death accounted for 28.80% of all-cause death. The 5 leading causes of cancer death were cancers of the lung & bronchus, stomach, liver, colon & rectum, and esophagus. Age-standardized mortality of all cancers was higher in men than in women (153.1/105vs. 88.8/105, p<0.001) and increased from 1974 to 1991 and decreased thereafter. The mortalities of cancers of the larynx, bladder, liver, nasopharynx, lung & bronchus, esophagus, lip oral & pharynx, stomach, kidney, and lymphoma were significantly higher in men than in women. Age-standardized mortalities of cancers of the esophagus, stomach, leukemia, female nasopharynx, female bladder, liver, and bone decreased especially after the 1990s, those of the colon & rectum, kidney, prostate, pancreas, breast, gallbladder, and ovary increased significantly. Lung cancer, breast cancer, colorectal cancer, and pancreas cancer in women and lung cancer, colorectal cancer, prostate cancer, and stomach cancer in men will be the leading causes of cancer death in 2025-2029. Cancer-caused life loss kept increasing since 2000. Conclusively, cancers associated with pollutions and infection decreased, especially after the 1990s, while those related to metabolic syndrome increased. These trends are related to closedown of polluted industries in the 1980s and lifestyle changes.

Abstract
Human papillomavirus infection is a major health problem and caused substantial benign and malignancy diseases among female and male worldwide. We aim to investigate the epidemiology of high-risk human papillomavirus (HR-HPV) and related diseases in Suzhou population. As well as evaluating the potential benefit of a nine-valent HPV vaccine (regardless of HPV-6 and -11) in Suzhou. A total of 40,108 people aged 13-89 years were retrospectively examined by database retrieval from 2010 to 2015. Thirteen genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 66) of HR-HPV were detected using Tellgenplex™ xMAP™ HPV DNA Test assay. The overall prevalence of HR-HPV was 21.1%, the female and male account for 96.4% and 3.6%, respectively. The infection rate among male (25.6%, 367/1,432) was significantly higher than that among female (20.9%, 8,100/38,676), X2 = 17.341 (P < 0.001), with OR = 1.293, 95% CI (1.146-1.460). The five most frequent HR-HPV genotypes were HPV-16 (5.12%), -52 (5.07%), -58 (3.02%), -39 (2.00%), and -18 (1.74%). HR-HPV infection rate was peak in person aged <20 years, and second higher in person aged 51-60 years. Infection modes as HPV-16, -18, -31, -33, -45, -52, -58 alone or mixed accounted for 63.2%. The top three prevalent diseases in HR-HPV infected women were cervicitis, vaginitis, and cervical lesions, and in men were verruca, urethritis, and balanitis, respectively. This is the first study to demonstrate HPV infection status in Suzhou population. Both women and men had a large burden of HPV infection. The nine-valent HPV prophylactic vaccines may potentially prevent 63.2% HR-HPV infection in Suzhou. J. Med. Virol. 89:895-901, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
FoodNet has provided a foundation for food safety policy and illness prevention since 1996. The Foodborne Diseases Active Surveillance Network (FoodNet) provides a foundation for food safety policy and illness prevention in the United States. FoodNet conducts active, population-based surveillance at 10 US sites for laboratory-confirmed infections of 9 bacterial and parasitic pathogens transmitted commonly through food and for hemolytic uremic syndrome. Through FoodNet, state and federal scientists collaborate to monitor trends in enteric illnesses, identify their sources, and implement special studies. FoodNet’s major contributions include establishment of reliable, active population-based surveillance of enteric diseases; development and implementation of epidemiologic studies to determine risk and protective factors for sporadic enteric infections; population and laboratory surveys that describe the features of gastrointestinal illnesses, medical care–seeking behavior, frequency of eating various foods, and laboratory practices; and development of a surveillance and research platform that can be adapted to address emerging issues. The importance of FoodNet’s ongoing contributions probably will grow as clinical, laboratory, and informatics technologies continue changing rapidly.

Abstract
A complete understanding of the natural history of infection with high-risk human papillomaviruses (HPVs) in cervical cancer requires data from regional and ethnic studies. The prevalence of high-risk HPVs was evaluated retrospectively in 2040 patients with cervicitis, 239 with cervical intraepithelial neoplasia grade 1 (CIN1), 242 with CIN2/3, and 42 patients with invasive squamous cell carcinoma (SCC) based on data from patients who visited our hospital between May 2013 and May 2015. The rates of high-risk HPV infection in patients with cervicitis, CIN1, CIN2/3, and invasive SCC were 40.8%, 74.9%, 70.2%, and 83.3%, respectively. The three most dominant HPV genotypes were HPV16, 58, and 52. HPV16 and HPV58 positivity in cervicitis, CIN1, CIN2/3, and SCC patients were 20.9% and 16.4%, 19.0% and 20.1%, 44.1% and 23.5%, and 60.0% and 31.4%, respectively. Compared to cervicitis, the odds ratios (ORs) for CIN2/3 in HPV16- and HPV58-positive patients were 2.99 (95% confidence interval [CI]: 1.32-4.33) and 1.56 (1.11-3.21), respectively; for SCC, the corresponding values were 5.68 (2.31-7.893) and 2.33 (1.41-3.87). Further identifying of carcinogenic HPVs and a fully aware of regional differences in HPV genotype distribution are tasks of top priority for cervical cancer control and prevention.
