The economic feasibility of timely implementation of anti-epidemic measures is substantiated. It is demonstrated that the delay in the implementation of an effective set of anti-epidemic measures, during the period of increasing morbidity, is associated with serious economic damage. It is shown that every day of «delay» in carrying out a set of measures during the outbreak of HFRS in the Saratov region in 2019 added 15 new cases of HFRS, which cost the budget 2,107,425 rubles daily. Calculations are given indicating that the implementation of timely anti-epidemic measures is highly cost-effective, since the benefits of the measures carried out significantly exceed the costs of their organization.

The multiplied load on medical organizations, forced use of unsuitable premises for treatment of people could not but affect disinfection activities. In addition, given the closed borders in 2020, there was a shortage of both raw materials and ready disinfectants on the market. On the one hand, this situation has led to an explosive interest of the business community in the disinfectants market. This is evidenced by the increased number of disinfectants registered in the Russian Federation from 164 in 2019 to 467 and 471 in 2020 and 2021, respectively. In this study, we analyzed technical specifications for the procurement of disinfectants by medical organizations posted on www.zakupki.gov.ru. Despite the fact that during the period there were relaxations in the procurement legislation that allowed medical organizations to directly purchase disinfectants from suppliers, the analysis revealed significant deviations in 2020 and 2021 in the consumption of disinfectants compared to 2017–2019 and 2022. For example, the consumption of disinfectants based on sodium hypochlorite increased significantly. Also, with the shortage and increased cost of alcohol-based skin antiseptics, purchases of soaps with antibacterial properties have increased, which is especially noticeable in 2021. However, the 2022 purchases indicate that healthcare organizations are returning to normal operations and their consumption of disinfectants is becoming similar to that seen in 2017–2019. Keywords: disinfectants, auctions, hospital-acquired infection.","PeriodicalId":502737,"journal":{"name":"Disinfection affairs","volume":"57 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140271660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the analysis of 11 scientific articles on the topic of the characteristics of epidemic foci in the teams of medical workers. Results and discussions. The COVID-19 pandemic has demonstrated the importance of developing national bed resources and the human resources of medical workers, taking into account the need for rapid conversion of somatic hospitals. Doctors, mid-level and junior medical personnel are at higher risk of infection both through contact with patients if they do not follow the rules for using PPE, and when interacting with each other. Repurposed somatic hospitals (GBUZ SB «SOKB named after V.D. Seredavina», FGBI VO «Clinics of SamSMU»), in comparison with a specialized infectious diseases hospital (GBUZ SB «GBS № 6»), due to the peculiarities of construction and planning solutions, represent an environment with a higher risk of infection of medical personnel, which requires additional organizational preventive measures. In addition to the general requirements of biological safety in the repurposed red zone, a comprehensive formation of a safe working environment is required, including such components as: organization of rest rooms for staff separately from the residents, development and observance of a meal schedule to eliminate the intersection of personnel flows as much as possible, digitalization of medical documentation, time-limited reception of biomaterial in the laboratory, issuance of the results of research through an electronic information system.

Low efficiency of deratisation measures can be related both to resistance of rats and mice to blood anticoagulants and to low attractiveness of baits. Thus, low eatability of baits entails insufficient cumulation of poison and, as a consequence, insufficient toxic effect on the animal organism. This paper describes the results of experiments to study the degree of sensitivity of grey rat individuals to the second generation anticoagulants bromadiolone and brodifacoum, most commonly used in deratisation practice. Sensitivity was determined by direct injection of anticoagulant solutions in neutral solvent into the stomach. The mean lethal concentration calculated by Hill’s equation for a single gastric administration was 0.35 mg/kg for bromadialone and 0.182 mg/kg for brodifacoum. The data obtained can be used in calculating the required amount of bait that must be eaten by the rodent to achieve lethality.

The aim of the work is to evaluate the effect of DS on the stage of formation of V. cholerae O1 and O139 serogroups biofilms on biotic and abiotic substrates. Materials and methods. Combined and monobiofilms were obtained according to previously developed methods, the concentration of V. cholerae of planktonic and biofilm forms was evaluated by bacteriological method and polymerase chain reaction in real time (PCR-RV). The statistical significance of the differences in experimental data was assessed using Student criteria. Results. At the stage of cell adhesion, cholera vibrions in the combined biofilm showed resistance to the action of ethyl alcohol (10 and 20?%), chloramine (0.1 and 0.2?%) at exposure up to 20 min. The bactericidal effect, expressed in the absence of culture growth and positive results in PCR-RV, was observed in samples with the addition of hydrogen peroxide of all dilutions, ethyl alcohol (50?%) and chloramine (0.5 and 1.0?%). At the monolayer stage, resistance to the action of ethyl alcohol of all dilutions, hydrogen peroxide (0.1 and 0.2?%) was revealed at exposure up to 20 minutes. Under the action of chloramine of all dilutions and hydrogen peroxide (0.5 and 1.0?%), the absence of V. cholerae growth on agar was noted with positive values of their concentrations in PCR-RV. The effect of all DS on mature biofilms maintained the previous pattern. Abio- and biotic biofilms of V. cholerae O139 ctxAB?¬ and ctxAB+ showed resistance to ethyl alcohol of all dilutions, chloramine (0.1 and 0.2?%) at exposure up to 30 min. The bactericidal effect of hydrogen peroxide of all concentrations on abiotic biofilms of all strains and resistance of strains in biotic biofilms were noted.
