Ureaplasma urealyticum (UU) infection can spread quickly through populations, and is associated with cervical intraepithelial neoplasms, human papillomavirus infections, and mortality in newborns. This study aimed to provide information that could be used to protect public health and decrease the incidence and transmission of sexually transmitted diseases (STDs), particularly among childbearing women. Here, the epidemiology of UU infection was examined in Cheonan, South Korea. During 2006–2017, specimens collected from 4,893 patients were submitted for sexually transmitted disease screening with multiplex polymerase chain reaction (STD-PCR) assay. Data were analyzed for UU infection cases using the R statistical program and presented as the median and range. Categorical data were analyzed using the chi-square test, and p-values <0.05 were considered statistically significant. STD-PCR tests showed positive results in 17.8%, 9.0%, and 18.7% of the total patient population, men, and women, respectively. Individuals in their teens and twenties accounted for the largest proportions of UU-positive specimens. Although Mycoplasma hominis was the most prevalent bacteria in 2006, it was superseded by UU in 2017. Of 870 UU-positive specimens, 50.1%, 33.1%, 13.4%, and 2.8% had single, double, triple, and quadruple infection, respectively. UU was most common among Korean individuals in their twenties, indicating high risks of maternal-to-fetal transmission that should be addressed through rapid diagnosis, treatment, and management.
