Background: Congenital syphilis is a serious infection transmitted from an infected mother to the fetus during pregnancy, potentially leading to adverse outcomes such as miscarriage, stillbirth, preterm birth, or neonatal death. The global COVID-19 pandemic and associated lockdown measures have posed significant challenges not only to individuals but also to national socio-economic systems, adversely affecting the quality and accessibility of healthcare services. Aim: This study aimed to compare the incidence of congenital syphilis in Mongolia during the pre-COVID-19 period (2016–2020) and the post-COVID-19 period (2021–2025). Materials and Methods: A cross-sectional study design was employed. Data from all 361 registered cases of congenital syphilis between 2016 and 2025 were included in the analysis. Results: The incidence of congenital syphilis per 100,000 live births decreased from 65.8 in 2016–2020 to 34.5 in 2021–2025, representing a 47.6% reduction (RR=0.52, 95% CI: 0.42–0.66, p<0.001). Overall, 67% of cases were concentrated in Ulaanbaatar. The proportion of cases among mothers aged 15–19 years increased from 11.5% to 21.3%, and the majority of mothers had completed secondary education. Conclusion Although the incidence of congenital syphilis declined significantly following the COVID-19 pandemic, 13.0% of pregnant women receiving antenatal care did not undergo serological testing. This underscores the need to strengthen surveillance and reporting systems and to implement continuous education and awareness programs, particularly targeting young women and mothers.

GoalTo determine current and the most widely used methods of delivering health information to urban population aged 15-64.Materials and MethodsA two-stage proportional sampling method was used and 809 respondents aged 15-64 were involved. The data was collected using quantitative and qualitative methods. Quantitative data was processed using the SPSS 13 software. Error limit (e) of 0.05 was chosen as having a statistical probability.ResultsSurvey involved 809 respondents aged 15-64 from Ulaanbaatar, Bayan-ulgii aimag (western region), Huvshul aimag (forest region), Dornod aimag (eastern region) and Dundgovi aimag (central region) centers of which 357 are male and 452 female. TV is the most popular information source although there are no regular hours for health information; in particular NCDs. Respondents prefer to watch related programs at specific TV hours every week. In regards to ways of receiving information, respondents would like to see live TV programs (60.9%), short commercials or ads (29.7%), documentaries (24.1%) and entertainment shows (17.1%).Conclusions:1. The most popular sources for getting health information, specifically on NCDs, to the population are television, newspapers, magazines, the Internet and friends. There is no difference noticed in information sources between Ulaanbaatar and aimag centers.2. There is a need to deliver information to population aged 15-64 on general understanding of NCDs, their prevention, on healthy diet, avoidance of harmful habits such as use of alcohol and tobacco. The most effective ways to deliver the information to the target population are communication channels such as television, health professionals and facilities, health volunteers, newspapers, magazines, Internet and friends.
