INTRODUCTION. The epidemiological situation of infectious diseases in Poland in 2020, including pertussis cases, was significantly influenced by the limitation of interpersonal contacts introduced to reduce the transmission of SARS-CoV-2 virus. There was a reduction by more than half in the number of recorded pertussis cases, from 1,629 in 2019 to 753 in 2020. Pertussis is most dangerous for young children, however, it can get sick at any age, and the disease does not leave permanent immunity. Severe pertussis can also develop in the elderly, which may increase the risk of mortality. Adults usually have pertussis is mildly symptomatic and constitute an important reservoir of B. pertussis. The most effective strategy for the prevention of pertussis is still immunization of children in accordance with the Protective Vaccination Program, and in the case of adults, vaccination with the pertussis component in acellular form, repeated regularly every 10 years. OBJECTIVES. The aim of the study was to assess the epidemiological situation of pertussis in Poland in 2020 compared to the situation in previous years, with particular emphasis on the assessment of the vaccination status of children against pertussis. MATERIAL AND METHODS. The assessment of the epidemiological situation of pertussis in Poland was performed on the basis of the results of the analysis of unit reports of pertussis registered in the NIPH NIH – NRI in the EpiBaza system and data from the annual bulletin “Infectious diseases and poisonings in Poland in 2020” and the bulletin “Vaccinations in Poland in 2020”. RESULTS. In 2020, 753 cases of pertussis were registered. The incidence was 1.96 per 100,000 population and was lower compared to the incidence in 2019 (4.24). The highest incidence of pertussis occurred in the age group 0-4 years (9.9), and high in children and adolescents aged 5-9 years (5.1) and 10-14 years (6.0 per 100,000 population). About half of the cases concerned people over 15 years of age. In general, a higher incidence of women was observed than that of men, as well as a greater number of cases in cities than in rural areas. In 2020, among people suffering from pertussis, 206 people (i.e. 27%) required hospitalization. In 2020, one fatal case of the disease was reported to the epidemiological surveillance system. SUMMARY AND CONCLUSIONS. In Poland, in 2020, there was a decrease in the number of pertussis cases by more than a half compared to the previous year. Despite the decline in disease rates, pertussis remains a public health problem as immunization-induced immunity is not sustained throughout life. Increasing the number of people susceptible to pertussis may lead to compensatory epidemics in the future, therefore the highest possible level of vaccination of the population, >92-94%, should be maintained to prevent new cases of pertussis.

ФГБОУ ДПО Российская медицинская академия непрерывного профессионального образования (РМАНПО) Минздрава России, Москва Актуальность проблемы сочетанной инфекции COVID-19 с ОРИ различной этиологии обусловлена высокой распространенностью респираторных инфекций в период эпидемии коронавирусной инфекции. Распространенность сочетанных инфекций COVID-19 с ОРИ по данным литературы варьирует от 0,6 до 45%. Исследования, посвященные особенностям течения сочетанных инфекций COVID-19 с ОРИ различной этиологии у детей, единичны, разнонаправленны и дискуссионны, что требует дальнейшего изучения данной проблемы.

IntroductionNon-pharmacologic interventions (NPIs), such as universal masking, implemented during the SARS-CoV-2 pandemic have reduced respiratory infections among children. This study focuses on evaluating the impact of NPIs onMycoplasma pneumoniaeinfections in children, analyzing data from two hospitals in Arkansas, and examining age-related differences and coinfections with other viruses.MethodsThe study was approved by the Institutional Review Board and included patients aged ≤18 years with upper respiratory tract symptoms. Data from the FilmArray® Respiratory Panel (FARP) were collected and divided into pre-NPI and NPI periods for analysis. Total test positivity rate and interval change in the positivity rate were evaluated. Statistical differences were determined by Chi-square (χ2-independence) analysis.ResultsA total of 68,949 tests were performed with a statistical increase in testing during the NPI period. The overall test positivity rate forM. pneumoniaedecreased by 74% (0.86% to 0.03%) during the NPI period, and the preschool age group had the highest number of positive tests in the pre- and NPI periods (Pre-NPI: n=40, NPI: n=12 positive tests, p=<0.001). The reduction inM. pneumoniaeinfections was consistent across age groups. Coinfections with other respiratory viruses, particularly human rhinovirus/enterovirus, were observed at much lower levels.ConclusionsNPIs effectively reducedM. pneumoniaein pediatric patients in Arkansas, and coinfections with specific viruses still occurred, albeit at lower levels during the SARS-CoV-2 pandemic. As NPIs are relaxed and the pandemic ends, we expectM. pneumoniaeinfections to return to pre-pandemic levels within the next 1-2 years.
