AIM. The aim of this study was to train dentists on the different oral hygiene measures to be followed by COVID-19 patients via Webinar and Information Education Communication (IEC) Materials and compare the effectiveness of both. METHODOLOGY. A total of 100 dental professionals were included by non-probability convenience sampling. Webinar and IEC Materials on oral hygiene measures, oral symptoms, and management strategies during COVID-19 were created and training was conducted for all dental professionals who registered themselves. An online version of the self-administered questionnaire (English) was created on the official Edantseva website and circulated to all the registered participants to obtain the pre and post-training data. RESULTS. Out of the total 80 participants in the Webinar group, 47 were females and 33 were males. Comparing the mean total scores obtained by the participants in the webinar and IEC groups in the pre and post-test showed that there is a significant difference in the scores obtained by the participants in the two groups in the pre and post-test (p<0.01). CONCLUSION. Educating dentists via IEC Materials was effective in improving their knowledge regarding oral health management during the COVID-19 pandemic. IEC materials being handy and referable at any time was found to be more effective.

Kazimierz Funk, born on February 23, 1884, in Warsaw, demonstrated an early inclination toward the field of human physiology. He charted his scientific trajectory within esteemed European scientific institutions, commencing at the age of 16 in Geneva, where he pursued studies in natural sciences. Subsequently, he continued his academic endeavors in Bern, culminating in the attainment of his doctorate in 1904. Following this, Funk relocated to Paris and secured a position at the Pasteur Institute. In France, his research concentrated on elucidating the role of trace elements in the human body. In 1906 he transitioned to Berlin, collaborating with Hermann Fisher (1852-1919) to investigate proteins and cancer processes. In 1910, Funk ventured to London, joining the Lister Institute, where he initiated research on beriberi disease. His investigations led to the isolation of a substance pivotal in treating the ailment, which he termed "vitamin" (derived from 'vita' meaning life and 'amine' indicating a nitrogen-containing compound). Despite four nominations for the Nobel Prize (in 1914, 1925, 1926, and 1946), Kazimierz Funk didn't receive the prestigious accolade. In 1925, at the urging of Dr. Ludwik Rajchman (1881-1965), the director of the National Institute of Hygiene, Funk assumed the directorship of the Biochemistry and Hygiene of Nutrition Branch at the National School of Hygiene. Under Funk's guidance, Poland became the third European country to produce insulin. Kazimierz Funk passed away on November 19, 1967, in New York City, at the age of 83. His significant contributions to the fields of biochemistry and nutrition endure as a testament to his enduring impact on scientific understanding. This proposal aims to condense and emphasise Kazimierz Funk's diverse scientific interests and the various scientific teams and sites he collaborated with, which ultimately led to his groundbreaking discover.

The exponential increase in internet use and the consequent surge in data generation present both opportunities and challenges for public health. Infodemiology, an emerging field at the intersection of information science and public health, seeks to harness the vast amounts of health-related data generated online for public health benefits. This paper provides a comprehensive overview of infodemiology, examining its development, methodologies, and potential to address public health challenges. We discuss the role of infodemiology in identifying and mitigating the spread of misinformation, especially in the context of the COVID-19 pandemic, which underscored the dangers of the "infodemic" - an overabundance of information, both accurate and not, that complicates public health responses. Through both demand and supply-based studies, infodemiology offers unique insights into health trends, misinformation dynamics, and the digital behaviors of health information seekers. Tools such as sentiment analysis are highlighted as essential in navigating the vast digital landscape for real-time health data analysis. Despite the potential of infodemiology, challenges such as data overload or misinformation. The paper concludes by emphasizing the importance of interdisciplinary collaboration, the development of advanced analytical tools, and the need for guidelines to maximize the field's impact on public health policy and practice.

Introduction: Giardiosis is a parasitic disease caused by the protozoa Giardia lamblia (also known as Giardia intestinalis and Giardia duodenalis), which causes gastrointestinal symptoms. Infection usually occurs through the ingestion of contaminated water/food or through contact with an infected person. In Poland, giardiasis is notifiable disease, acoording to the EU deffinition implement in the polish surveillance system.

Aim of the study: The aim of this study is to asses epidemiological situation of giardiasis in Poland in 2021 and compare it to the previous years.

Materials and methods: The assessment of the epidemiological situation of giardiasis in Poland in 2021 was performed on the basis of data from the annual bulletins "Infectious diseases and poisoning in Poland" for the years 2008-2021, data on individual cases collected for the purposes of epidemiological surveillance in the EpiBaza system and data from food-born outbreak investigations recorded in the Registry of Epidemic Outbreaks (ROE).

Results: In 2021, 559 cases of giardiasis were reported in Poland (558 confirmed case, 1 probable case). There was an increase in the number of reported cases in comparision to 2020 by 56% and decrease to 2019 by 29%. Cases of giardiasis were reported in all voivodeships, with the highest incidence rate in Podlaskie voivodeship (9.1/100 000), incidence rate for Poland was 1.5/100 000. Giardiasis was diagnosed in patiens in all age group, the largest group of patiens were children (age groups 0-4 and 5-9). The hospitalization rate of patients diagnosed with giardiasis was 9.7% and was lower than in 2020, when it was 12.4%. As in previous years, no deaths from giardiasis were reported.

Conclusions: The number of cases of giardiasis has increased compared to 2020, but has not reached pre-pandemic levels. As in previous years, differences in the incidence by age and sex of people with the disease were noted when comparing data reported from Poland and EU/EEA countries.

Background: Despite a temporary decrease in the number of newly HIV infections in Poland in 2020, a return to the growing number of new infections was observed in 2021 in the surveillance.

Objective: The aim of the study was to assess the epidemiological situation of newly HIV infections and AIDS cases and death among AIDS cases in Poland in 2021 in comparison to the changes in preceding years.

Material and methods: Analysis of the epidemiological situation was based on reports of newly detected HIV cases and AIDS cases received from doctors and laboratories and the results of the annual survey of HIV testing conducted by laboratories throughout the country. A dataset on clients from Voluntary Testing and Counselling, coordinated by the National AIDS Center, which anonymously collects epidemiological and behaviour data on tested people was used.

Results: In 2021 there were 1 367 HIV cases newly diagnosed in Poland (diagnosis rate 3.58 per 100,000), including 236 among non-Polish citizens. The number of HIV infections increased by 43.3% compared to the previous year and was higher by 3.8% compared to the median in 2015-2019 years. Similarly, among VCT clients, number of HIV increased by 45%, from 309 in 2020 to 448 in 2021 year. The total number of AIDS cases reported to surveillance was 62 (incidence 0.16 per 100,000). The HIV infection was most often detected in the age group 30-39 year (35.8%) and among men (82.1%). Among cases with known transmission route, 68.7% concerned among MSM. The percentage of AIDS cases diagnosed at the same time with HIV increased by more than 30 percent points (from 63.5% to 95.1% of all AIDS cases).

Conclusions: In 2021 the number of newly detected HIV infections increased compared to the previous year, probably due to a reduction in restrictions related to the COVID-19 pandemic and increased in HIV testing rate.

OBJECTIVE OF THE WORK. As 2021 was the second year of COVID-19 pandemic we expect the continuous impact of the pandemic on other infectious diseases. We aimed at reviewing the national infectious surveillance data based on available surveillance reports (Epidemiological Chronicle) to summarize the infectious disease situation in 2021. MATERIAL AND METHODS. National infectious disease surveillance system collects mandatory notifications from physicians and laboratories as well as epidemiological investigation reports prepared by State Sanitary Inspection, where relevant. We also include mortality data based on the reports of Statistics Poland office. RESULTS AND DISCUSSION. In 2021, there were 2,852,789 cases of COVID-19 reported, corresponding to the incidence of 7475.4 per 100,000 and 90,126 deaths related to COVID-19. For most of diseases the incidence remained lower than before the pandemic. This included influenzea and influenzea-like illness incidence (- 5.4% vs 2020 and - 37.6% vs median 2015-2019) and tuberculosis incidence (+9.3% vs 2020 and -35.9% vs median 2015-2019). The incidence was lower than in 2020 for: pertussis (-75.7%), measles (-54.9%), rubella (48.7%), mumps (-16.4%), chickenpox (-19.0%) or H. influenzea invasive disease (-33.0%). A notable exception to these trends was Clostridium difficile intestinal infections incidence, which was higher by 88.2% from the 2015-2019 median with 21,157 case and 1,120 fatalities reported in 2021. There was also an almost 4-fold increase in norovirus infections incidence. The number of chronic hepatitis infections diagnoses were substantially lower than median for 2015-2019 (-53.7% for HBV and - 68.8% for HCV). The COVID-19 pandemic still played the crucial role as a public health problem, but its impact on other infectious diseases was less clear than in 2020. The reduction in the number of registered cases was with likely attributable to non-pharmaceutic interventions and to delays in registration due to reduced public health resources.

Background: The incidence of gonorrhoea at the European level increased over 2012-2019, decreased in 2020, and then reached higher values in 2021 than in 2019.

Objective: Analysis in the descriptive epidemiology scheme of gonorrhoea notification in surveillance in Poland in 2021 (being the second year of the COVID-19 pandemic).

Material and methods: Case-base data from surveillance of gonorrhoea were used: confirmed case (meeting laboratory criteria), probable (meeting clinical criteria and contact with confirmed case) and possible (only in Poland - physician diagnosed gonorrhoea, no information available for proper classification). Statistic Poland data was used to calculate the indicators. Data on patients treated in dermatology-venereology clinics between 2019-2021 were taken from the Bulletins of the Ministry of Health.

Results: The incidence of gonorrhoea in Poland in 2021 was only a fraction of recorded in the EU/EEA (0.74 vs. 13.7/100000)-similar to the first pandemic year and were about half of those notified in the 2019 (the peak year; 281 vs. 522 cases). There were 15.5 men per one female (incidence: 1.6/100000 men, 0.1/100000 women). Every second case was among aged 25-34 (49.62%), every fourth-aged 35-44 (23.11%). Under 15, no cases were reported. The predominant site was the genitourinary (excluding missing data: 85.3%). The cases with missing information on transmision increased (49.1%; aged 45+: 72.0%, women: 76.5%). Delays in reporting data were identified (greater than in 2019, however, less than in 2020), ~17% cases were from 2019-2020. Dermatology-venerology clinics treated 385 people - less than in 2020, however, more than reported in epidemiological surveillance (vs. 281).

Conclusions: The COVID-19 pandemic has influenced on the surveillance system in Poland. There are difficulties in interpreting the epidemiological trend. It is necessary to: 1) intensify systemic solutions in the area of prevention, including sexual partners; 2) raise the awareness of healthcare professionals and sanitary inspection workers on the role of collecting epidemiological information.

Introduction: Chickenpox is a highly contagious disease, but one that can be effectively prevented by vaccination. In Poland, vaccination against the disease is recommended, paid for, and chickenpox remains very common. In recent years, starting in 2002, the upward trend in the incidence of chickenpox has continued, except in 2020. In 2020, there was a decrease in incidence.

Objectives: The aim of this study was to evaluate epidemiological indicators of chickenpox in Poland in 2021 compared to previous years, taking into account the impact of the COVID-19 pandemic.

Material and methods: The evaluation of the epidemiological situation of chickenpox in Poland in 2021 was carried out based on the results of the analysis of aggregate data published in the annual bulletins: "Infectious Diseases and Poisons in Poland in 2021" and "Immunization in Poland in 2021". In addition, recommendations from the 2021 Immunization Program are described.

Results: 57,669 cases of chickenpox were registered in Poland in 2021, 42% less than in the previous year. The incidence of chickenpox in 2021 was 151.1 per 100,000, which was lower than in 2020, as well as in 2019, when it was 470.6/100,000. The lowest incidence was registered in Lower Silesia Province - 99.2/100,000, while the highest in Silesia Province - 215.8/100,000. The highest incidence was in children aged 0-4 years (18,028). The incidence of chickenpox in males was higher than in females (159.5 vs. 143.3/100 thousand), and urban residents were higher than rural residents (152.1 vs. 149.6/100 thousand). Hospitalization due to chickenpox in 2021 included 210 people, which accounted for 0.36% of the total number of registered cases.

Conclusions: In 2021, there was a decrease in the number of chickenpox cases compared to the previous year. The lower incidence may have been the result of a decrease in the transmission of the chickenpox virus, the decrease in the number of cases has to do with, among other things, the restrictions put in place in connection with the COVID-19 pandemic, which result in, among other things, reduced human contact, the wearing of masks and increased social distance.

Introduction: Mumps is a contagious viral disease occurring mainly in children, the source of infection being the sick/infected person. Since 2003, vaccination against mumps has been mandatory in Poland, performed according to a two-dose schedule. As part of the Public Health Immunization Program (PSO), the MMR combination vaccine (against measles, mumps and rubella) is used for the entire population of children.

Objectives: The aim of this study was to evaluate epidemiological indicators of mumps in Poland in 2021 compared to previous years, taking into account the impact of the COVID-19 pandemic.

Material and methods: The analysis of the epidemiological situation of mumps in Poland in 2021 was based on the interpretation of data from the bulletin , "Infectious diseases and poisonings in Poland in 2021" and , "Immunization in Poland in 2021".

Results: 484 cases of mumps were registered in Poland in 2021. The total incidence was 1.3 per 100,000 residents, which was lower than in 2020. The highest incidence of 1.8 per 100,000 residents was registered in Pomorskie Province, and the lowest incidence of 0.7 in Lower Silesia Province. The highest incidence (6.4/100 thousand) was recorded in children aged 0-4 and 5-9. The incidence rate for men (1.4/100,000) was higher than for women (1.1). In 2021, there were 9 patients hospitalized due to mumps, this was more than in 2020.

Conclusions: The decrease in the number of cases of mumps in 2021 remained related to the ongoing pandemic - the restrictions introduced during the pandemic period led to a decrease in the number of cases not only of COVID-19, but also of other diseases spread by the droplet route, including mumps. The number of registered cases based on the reports of diagnosing physicians may be underestimating the actual number of cases due to the continued difficult access of patients to primary care physicians.
