Prevalence of high and low risk HPV genotypes among vaccinated and non-vaccinated people in Tehran.

ABSTRACT

BACKGROUND: Human Papillomavirus (HPV) is a prevalent STI (Sexually Transmitted Infection) that is estimated almost all sexually active Patients at some stage of their life will be infected by the virus. Although most HPV infections resolve spontaneously, some can result in health complications, such as genital warts and several types of cancer. This study analyzed the variety of HPV genotypes in females and males among the infected population. METHODS: Samples were obtained from the oral, vaginal, and genital sites of study participants and the samples underwent DNA extraction and subsequently amplified using Real-Time PCR. The recognition of high-risk (HR) and low-risk (LR) HPV genotypes was carried out using the HPV REALQUALITY RQ-Multi diagnostic kit and demographic information was analyzed alongside statistical virological data. RESULTS: Out of 936 samples, 324 cases (34.6%) were found to be positive for HPV, while 612 cases (65.4%) were negative. Of our participants, 70 samples of males (27.5%) and 254 samples of females (37.3%) were HPV-positive. Common genotypes included 16, 6, 11, and 18, while genotypes 59, 56, 31, 45, and 52 were also detected. CONCLUSION: According to the findings of this study, a significant prevalence of HPV infection was seen in males and females, and the incidence of high-risk genotypes was more diverse in males. While the vaccine was effective in preventing some types of HPV, such as 16, 18, 6, and 11, there seems to be an increase in infections caused by other genotypes, and precautions should be taken to prevent future health problems.
