“…Such knowledge at the level of institutions, regions or entire countries can be very useful for the management of anti-pandemic measures. Therefore, it is not surprising that the results of such seroepidemiological studies are presented in dozens of scientific publications (Anda et al, 2022;Fernández-Rojas et al, 2022;Goldfarb et a.l, 2022;Lewin et al, 2022;Mahallawi et al, 2022;Mercado-Reyes et a.l, 2022;Olariu et al, 2022;Prakash et al, 2022;Prguda-Mujic et al, 2022).…”

Slovakia is a country with only 5.45 million inhabitants. However, the past two years of the COVID-19 pandemic have shown huge interregional differences. These were represented by different numbers of diagnosed SARS-CoV-2 cases and the vaccination rates in the regions, as well as by the willingness of the inhabitants to comply with anti-pandemic measures or to undergo testing. The occurrence of such regional disparities provided a rational basis for monitoring the epidemic situation within smaller areas, e.g. at city level.

Background and Objectives: The aim of this research was to assess the spread of SARS-CoV-2 infection; the study was motivated by parental hesitancy regarding child vaccination, and the potential passive immunity of infants acquired through breastfeeding from mothers vaccinated against COVID-19 or infected with SARS-CoV-2. Materials and Methods: We quantified the anti-SARS-CoV-2 immunoglobulin G (IgG) titer in the serum of 743 children under 5 years old, hospitalized between 1 August 2022, and 15 September 2023. Results: Among the participants, 52.76% had an anti-SARS-CoV-2 IgG titer that exceeded the reactivity threshold of the kit used, with an average of 1558.01 U/mL across the entire group. By age-specific categories, SARS-CoV-2 antibody prevalence was 43.04% for 0–12 months, 42.22% for 12–24 months, 61.67% for 24–36 months, 65.17% for 36–48 months, and 68.55% for 48–59 months. Gender analysis revealed 55.32% male participants, with a 52.07% seropositivity rate. Notably, IgG titer correlated positively with the child’s age. Gender, admission diagnosis, and emergency department presentation were not variation factors of the IgG titer. Conclusions: The majority of children in the study group demonstrated IgG against SARS-CoV-2, and this rate increased with the child’s age. Also, the IgG titer increased with the child’s age.
