Background: Legionnaires' disease is a type of severe pneumonia caused by Legionella bacteria. The case fatality rate in this disease is 5-10%. People with various comorbidities, smokers and the elderly are at greater risk of developing the disease.

Objective: The aim of the work is to present the results of an epidemiological investigation into the outbreak of Legionnaires' disease that occurred in the city of Rzeszów and the surrounding area in August and September 2023 and to present the threat related to the presence of Legionella bacteria in water supply installations and networks.

Material and methods: The material for this publication was data from an epidemiological investigation conducted in the outbreak of Legionnaires disease in Rzeszów in 2023.

Results: Epidemiological investigation revealed 165 cases of Legionnaires' disease in the outbreak, including 152 confirmed cases and 13 probable cases. The case fatality rate in a legionellosis outbreak was 15%. Environmental tests were carried out in residential and public buildings and industrial installations during the investigation. As part of environmental tests, 187 water samples were collected, including 87 warm water samples.

Conclusions: The outbreak of Legionnaires' disease in the city of Rzeszów draws attention to the potential threat from the Legionella bacteria to the health and life of especially elderly people suffering from chronic diseases. The environmental tests carried out confirmed the highest number of Legionella bacteria at medium and high levels in water samples taken in the private apartments of sick people. Despite the lack of strict legal regulations clearly specifying the obligations regarding periodic disinfection of internal hot water supply installations, cooperation with their owners should be undertaken to enforce plans and actions in this area.

Zoonoses, diseases transmitted from animals to humans, continue to challenge public health despite advancements in controlling infectious diseases. The intricate link between human, animal, and environmental health is emphasised by the fact that zoonoses contribute to 60% of emerging human infections. Wet markets, wildlife hunting, intensive wildlife farming, and interactions between domestic animals and humans are key transmission sources. Historical examples like the bubonic plague and English Sweats illustrate the longstanding impact of zoonotic diseases. With new transmission patterns emerging, it is necessary to use new techniques to predict disease spread. This article delves into the emergence of new zoonoses, such as the Nipah virus and the SARS-CoV-2 pandemic, emphasizing the importance of understanding zoonotic aspects for outbreak prevention. Re-emerging zoonoses, like tuberculosis and vaccine-preventable diseases, present challenges, exacerbated by factors like globalized human activities and disruptions caused by the COVID-19 pandemic. Public health implications are explored, including economic losses, antibiotic resistance, and the disruption of international trade.

Introduction: Tuberculosis (TB) is a significant global health concern, particularly in developing countries. Diagnosing latent tuberculosis infection (LTBI) in hemodialysis patients is crucial because of the risk of developing active tuberculosis in this population due to attenuated immune response. Herein, we assessed the prevalence of LTBI in hemodialysis patients.

Methods: In this cross-sectional study, we included all patients referred to hemodialysis centers in Kohgiluyeh and Boyer-Ahmad Province, southwest Iran, in 2018 through census sampling. Tuberculin skin test (TST) was utilized to screen the patients for LTBI. All steps were done by trained physicians.

Results: In total, 183 patients (mean age: 59.3, SD= 16.0) were included in the study of which 76 (41.5%) were females, and 107 (58.5%) were males. Neither the patients nor their family members had a history of tuberculosis. Assuming an above 5-millimeter enduration as a positive TST result, 22 patients (12%) had LTBI. None of the demographic or clinical features differed between TST -negative and -positive groups.

Conclusion: Hemodialysis patients are prone to LTBI due to several immunological and environmental factors. Screening for LTBI may be beneficial to prevent active tuberculosis in this population.

Slackia exigua, originally classified as Eubacterium exiguum, is a Gram-positive, asaccharolytic, rod-shaped anaerobic bacterium. The virulence factors of S. exigua have not been accurately identified. The objective of the study is to evaluate the pathogenic potential of S. exigua by presenting the cases of infections diagnosed at our hospital laboratory. Additionally, we reviewed the literature to summarize the experience with S. exigua infections to clarify, in the light of current knowledge, the clinical picture, diagnostic, and therapeutic issues related to this anaerobic bacterium. We reported eleven severe human infections caused by S. exigua. All patients required hospitalization. Nine of the cases involved chronic infections in the stomatognathic system, in two patients, skin infections were diagnosed. As it is known, S. exigua is a component of the human microbiota; however, it can cause opportunistic infections, particularly in the case of translocation outside its natural habitat. A critical literature analysis revealed that S. exigua can be responsible for bacteremia, meningitis, tissue necrosis, periprosthetic joint infection, and osteomyelitis. Several studies have been published regarding the determination of drug susceptibility of S. exigua. The isolated strains were susceptible to most antibiotics used for the treatment of anaerobic infections. The interpretation of antimicrobial susceptibility testing for some slow-growing in vitro, infrequently causing infections anaerobic bacteria, such as S. exigua, is based on The European Committee on Antimicrobial Susceptibility Testing (EUCAST) additional guidance taking into account the determination of drug susceptibility for groups of microorganisms for which cut-off values have not been developed.

Actinomycosis is a very rare, infectious disease, which is especially difficult to diagnose due to non-specific symptoms and the ability to emulate neoplasms or inflammatory changes. Due to those facts, it is often misdiagnosed or diagnosed too late to be successfully treated. This article presents the case of 31-year-old Caucasian female with recurrent upper respiratory tract infections and tonsillitis as the potential risk factors of actinomycosis. Upon examination of material collected through the course of tonsillectomy, the patient was diagnosed with actinomycosis of the left palatine tonsil. Despite the introduction of antibiotic therapy, initial progression was noted with the appearance of numerous, hypodense changes in the liver and the spleen, which regressed during further antibiotic treatment. According to our team's knowledge, this is the first described case of a patient with actinomycosis occurring simultaneously in the cervico-facial and abdominal area. The unusual localization and potential dissemination of actinomycosis should be considered in clinical practice.

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.

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.

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.
