Insights

This study found that over half of Pap smear exams revealed infections, with Gardnerella vaginalis and Trichomonas vaginalis being the most common. These high rates of genital infections indicate a significant public health concern requiring increased awareness and control measures.

Area of Science:

  • Gynecology
  • Microbiology
  • Public Health

Background:

  • Urinary tract infections are common human infections caused by various microorganisms.
  • Vaginal infections are a significant component of overall human infections.
  • Routine cytological exams, like Pap smears, can detect these infectious agents.

Purpose of the Study:

  • To determine the prevalence of vaginal infection-causing agents in routine Pap smear screenings.
  • To evaluate the characteristics of Pap smears positive for infectious agents.
  • To assess the public health implications of identified genital infections.

Main Methods:

  • A retrospective, descriptive study was conducted in a Clinical Pathology laboratory.
  • Data from 18,645 Pap smear exams performed between 2013 and 2017 were analyzed.
  • Results for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp., and HPV, along with coinfections, were recorded.

Main Results:

  • Over half of the analyzed Pap smear exams showed infections, with rates varying annually.
  • A total of 21.84% of exams (4,073) presented infections, primarily caused by Gardnerella vaginalis and Trichomonas vaginalis.
  • High rates of coinfection with Candida spp. were also observed.

Conclusions:

  • The study highlights a significant public health issue due to the high prevalence of genital infections.
  • There is a need for enhanced monitoring, guidance, and public awareness campaigns for prevention.
  • Effective control strategies are crucial to manage the burden of these infections.
