Aim Hand hygiene practice is still burdened by inadequate compliance, whether in the professional sphere by health professionals or in the non-professional sphere by lay population. Aim of this study was to map the hand hygiene knowledge and its compliance in the monitored group of people. MethodsThe research was conducted at the Jessenius Faculty of Medicine in Martin of Comenius University in Bratislava (JFM CU) among seventy 3 rd year students of General Medicine (medical study program), and Nursing, Midwifery and Public Health (non-medical study programs). Knowledge of hygienic hand washing according to the WHO guidelines from 2009 was investigated, as well as differences in the level of microbial contamination of hands after routine hand washing between the group that had been acquainted with hand hygiene protocols and the group that had not sufficiently. ResultsThe results have shown that 32.9% of the students did not perform hygienic hand washing properly. The differences between the groups of students with and without the proper hand hygiene compliance in routine hand washing were not statistically significant. Conclusion The results of our survey have suggested that the reasons for decreased compliance with hand washing protocols may be related to forgetting to wash the hands or not being acquainted with hand washing protocols at all. The strategies focused only on one aspect of hand hygiene are, according to scientific literature, ineffective in the long term.

We aimed to characterize Clostridioides difficile isolates cultured during a six-month single-center study from stool samples of patients with C. difficile infection (CDI) genotyped by the Xpert^®C. difficile/Epi assay by polymerase chain reaction (PCR) ribotyping, toxin genes’ detection and multi-locus variable number tandem repeats analysis (MLVA). The susceptibility to metronidazole, vancomycin and moxifloxacin was determined by agar dilution. In addition, the presence of Thr82Ile in the GyrA and a single nucleotide deletion at position (Δ117) in the tcdC gene were investigated. Between January 1 and June 30, 2016, of 114 CDIs, 75 cases were genotyped as presumptive PCR ribotype (RT) 027 infections using a commercial assay. C. difficile isolates cultured from presumptive RT027 stool samples belonged to RT176. These isolates carried genes for toxin A (tcdA), B (tcdB), binary (cdtA/B) and had Δ117 in the tcdC gene. Using MLVA, the 71/75 isolates clustered into two clonal complexes (CCs). Of these, 39 isolates (54.9%) were from patients hospitalized in acute care and 32 isolates (45.1%) were isolated from patients hospitalized in the long-term care department. All isolates were susceptible to metronidazole and vancomycin, and 105 isolates were resistant to moxifloxacin (92%) carrying Thr83Ile in the GyrA. An outbreak of RT176 CDIs, suspected as RT027, was recognized in a Slovakian hospital. In order to monitor the emergence and spread of RT027-variants, the identification of a presumptive RT027 CDI should be confirmed at a strain level by PCR ribotyping.

Background: Despite the effective National Immunization Programme of Slovakia, some population groups are incompletely vaccinated or unvaccinated. We aimed to describe the measles outbreak spread in Eastern Slovakia between May and October 2018, affecting the Roma communities in relation to the existing immunity gaps. Methods: We defined a group of persons living in socially closed communities with low vaccination coverage. Results: Of 439 measles cases (median age: 10 years), 264 (60.1%) were vaccinated, 137 (31.2%) received two doses and 127 (28.9%) one dose of measles vaccines, 155 (35.3%) were unvaccinated and 20 (4.6%) had an unknown vaccination status. Samples from 102 patients (with two-dose vaccination status) were additionally tested for antibodies against rubella and mumps. Of 102 cases, 68 (66.7%) cases had a positive IgM and 23 (22.5 %) IgG antibodies against measles. For rubella, only 20 (19.6%) cases had seropositive IgG levels, for mumps higher positivity was detected in 60 persons (58.8%). We could detect only a small percentage with positive serology results of rubella IgG antibodies across all age groups. We have assumed that rubella antibodies had to be produced following the vaccination. Their absence in the cases with two doses of MMR suggests that these vaccines could not have been administrated despite the fact that this data was included in the medical records. Sequential analysis of two samples showed measles genotype B3. Conclusion: This outbreak can outline the existence of a vulnerable group of the Roma. Low vaccinate coverage represents a serious public health threat.

Introduction: Decrease of nonspecific imunity in patients and the treatment with broad spectrum antibiotics form appropriate conditions for the appearance of medically severe Clostridium difficile infection (CDI) - enterocolitis that can have the characteristics of community or hospital acquired infection (HAI). The aim of our work is to identify the trend of their incidence in Slovakia and to define the risk groups according to age and department of hospitalisation. Material and Methods: Retrospective analysis and comparison of the appearance of CDI was performed within the groups of patients hospitalised in health care institutions in the SR and those in the district of Martin during the period of years 2010 to 2017. The data of reported cases were taken from the Epidemiological information system of the Slovak Republic (EPIS SR), the source of demografic data was the National Center of Health Information. Resuts: Analysis shows an important increase of incidence of CDI during years 2010 to 2017. Diseases had predominantly health care associated – nosocomial – character targeting mostly older patients (65+ - 24/10 000 in the Slovak Republic and 62/10,000 in the county of Martin) and less infants (7/10,000 and 11/10,000 repectively). Conclusion: The results of our analyses are consistent with literature data about CDI enterocolitis and show their serious health and social impact in our society.

Vaccination against measles is one of the most effective public health interventions which has saved millions of lives and interrupted circulation of the natural virus in the population. However, it is widely accepted that the immunity after vaccination can wane, especially in those who have had no contact with the virus. This study aimed to classify the particular birth cohorts of adults with regard to their exposure to the wild measles virus in the population with a long history of mandatory vaccination. We introduced two methods. In the first, we estimated the probability of exposure to the wild virus through an analysis of antibody levels from the Immunologic Survey performed in the Slovak Republic in 2018, while the second was based on historical epidemiological data. Both methods resulted in similar estimations. Cohorts born in Slovakia before 1964 can be considered to be cohorts in which most people were exposed to the wild measles virus. Cohorts born after 1977 can be designated as cohorts that most likely did not come into the contact with the wild virus. Cohorts born between 1965 and 1976 are composed of a mixture, with a decreasing proportion of people exposed to the wild virus with increasing year of birth. The proposed methods can help identify potential immunity gaps in the adult population. They can be applied in other countries with high measles vaccination coverage to estimate the probability of exposure to the wild measles virus in particular birth cohorts.

Background/Objectives: This study analyzed data on the actual timing of the first and second doses of the Measles, Mumps, and Rubella (MMR) vaccination in Slovakia according to the vaccination schedule. Methods: Histograms were constructed using immunological survey data on MMR vaccination conducted in Slovakia in 2018. Results: For the first dose (2560 individuals), 83.4% of them were vaccinated timely (15th–18th month, mostly in the 16th month), while 13.8% of them were delayed. For the second dose (1061 individuals), 72.7% of vaccinations were timely (11th year), and 23.2% were delayed. There was a bimodal distribution of the timing of the administration of the second dose, with peaks at the beginning of the 11th year and at the turn of the 11th and 12th year. Conclusions: The unexpected shape of the histograms suggests that ambiguous interpretations of the vaccination schedule may be one of the causes of vaccination delays.
