Introduction: Sanitation facility supply and service availability of Mongolia is essential due to the slow process of bacterial decomposition which is getting significant difficulties because of the cold and arid climate. Only 37 percent of Ulaanbaatar’s population is connected to the central sewerage system, and the majority of ger area residents, or 95 percent, use pit latrines in demand of sanitation facility. Numerous studies have shown that the main contaminant of the soil in ger area were pit latrines. It not only pollutes the environment but also affects human health. There is a lack of awareness about the transmission of infectious diseases and options of new sanitation facilities and poor knowledge and bad conditions to introduce new drainage systems. Most pit latrines in ger areas are of poor quality and do not meet relevant standards. Goal: To determine the effect of ”Gipon” ionized disinfectant solution produced by Japanese technology for disinfecting pit latrines Material and Methods: This study was conducted in December 2019 using a random sampling method. Five households in ger areas were selected and pit latrines were disinfected by ”Gipon” ionized disinfectant solution. Results: The survey covered pit latrines of 5 households in the 21st khoroo of Bayanzurkh district. All owners allowed to participate in the survey. The pit latrines are located approximately 9.8 meters away from the households participated in survey. They have been utilized it for 7.6 years and used by an average of 6 people per day. For inner cover, 60.0 percent are lined with wood, and 40.0 percent are cleaned once a month. Before the use of the disinfectant solution, having taken the swab from door handles, floors and walls of the toilet and were detected Enterobacter spp, E.Coli, and Pseudomonas spp in all samples.
However, after one and 24 hours of spreading of the disinfectant solution, the amount of intestinal coliform bacteria and E. coli was reduced dramatically and in some places no bacterial were detected. 72% of the soil near the latrines in the study covered ger areas was contaminated with bacteria. In terms of E.Coli contamination in soil, 60% of them were contaminated in low degree and 32% were medium and 8% were high degree. Anaerobic microorganisms such as Cl.prefrings were accounted for 82% of the total sample, 19% moderate and 81% low contamination. Conclusion Intestinal coliform bacteria (Enterobacter spp, E.Coli, Pseudomonas spp) and pathogenic bacteria (Serratia spp, Staphylacoccus spp) were not detected and the number of fungi was sharply reduced after 1 and 24 hours using Hypon disinfectant. No intestinal pathogens (Salmonella spp, Citrobacter freundii) were found in the soil near the latrine. The amount of coli titers was reached to the acceptable limits. According to this study, the disinfection activity of “Gipon” solution was ranging from 105 to 104.

Introduction: Vaccination is a cost-effective intervention to prevent major illnesses that contribute to child mortality in the country. Increase in parental knowledge abour vaccination will lead to increase in vaccination rates of children. The main aim of our study was to assess the knowledge, attitudes and perceptions of vaccination. People’s knowledge about immunization and their attitudes toward them are likely influence uptake. Goal: The main purpose of the study is to evaluate the knowledge and attitude of the population towards measles and to clarify their satisfaction and understanding of the measles immunization program. Materials and Methods: We conducted cross-sectional study, involved participants from 3 aimags and 6 districts covered voluntarily. Total participants were 509. We used to online model and with the participant’s self-answer closed questionnaire. Results: 76% of the respondents were female and 24% were male. 64.1% of respondents who have children of 0 to 5 years of age, had little or bad knowledge towards immunization schedules against measles. Overall, the general attitude towards vaccines was positive, but the knowledge about significance of vaccines was weak. Further, district and province family doctors need to pay particular attention to increasing awareness and knowledge on importance of vaccines among families with young children. It is necessary to conduct extensive, long-term research and training among population to evaluate their knowledge and attitude towards measles, its vaccine and prevention, and to identify causes of lack of knowledge. Conclusion Our study shows the importance of good physician–patient communication in improving knowledge attitude and practice of parents towards their children’s vaccination.

Introduction: Researchers have found that people living in polluted areas have a lower ability to resist skin bacteria and increase the number of skin microflora. Decreased immune function increases the risk of sore throat, influenza, respiratory infections, pneumonia and gastrointestinal diseases. One of the main indicators of the human immune system is the normal microflora. Goal: To study the relationship between normal human microflora and specific immunity. Material and Methods: This study was conducted within the framework of the project “Effects of non-specific immune factors on injectable infectious disease immune system”. The survey sampled 10 households from Dornod aimag, 8th khoroo of Chingeltei district, Ulaanbaatar city, and 3rd khoroo of Baganuur district. A total of 176 people aged 6 months to 50 years were involved. A total of 528 swab samples and 31 blood samples were collected from the throat, tonsils, skin and mucous membranes to study the relationship between normal human microflora and specific immunity.
The research methodology was discussed at the meeting of the Academic Council of the Ministry of Social Welfare and the Medical Ethics Review Committee under the Ministry of Health (January 5, 2018, Resolution 646) and the research was approved. Results: The total number of normal microorganisms in the skin and mucous membranes of the study participants changed, and the number of hemolytic strains and fungi increased. 58%-67% of the participants had normal and long-term immunity against diphtheria and tetanus, while 5% -14% were not. This result was as high as in urban and rural areas. Conclusion This result was as high as in urban and rural areas. As the age group increases, the level of the body’s specific immunity decreases, the structure of the normal microflora changes, and the number of fungi and hemolytic bacteria increases. Furthermore, it is necessary to study specific and nonspecific immunity in detail in relation to environmental pollution indicators.
