International Organizations are seriously concerned about the fake news phenomenon. UNESCO has defined the term of misinformation/disinformation, which are the two faces of fake news. European Commission has conducted a survey about “Fake News” through EU citizens to estimate the awareness and people behaviour related to the appearance of fake news and disinformation on electronic. The findings are quite worrying, since about 40% come across fake news daily and 85% evaluate fake news as a problem. The aim of this work is to introduce an Artificial Intelligence approach, the Decision Trees algorithm to identify fake news on the COVID-19.

During the first months of COVID-19 pandemic, authorities of many countries imposed to educational institutions of all educational levels, the online delivery of their courses to prevent the spread of SARS-CoV-2. We investigated the perceptions and first experiences of Nursing students that attended the synchronous distance learning undergraduate course of Health Informatics. Respondents’ perceptions and experiences were positive regarding the design and material of the course and the discussions with their peers while the technical support was negatively rated. Students could not decide if distance learning is more difficult than traditional or whether distance learning is more time consuming than traditional learning. Nursing students prefer traditional learning as they stated that they learn more and feel more comfortable to participate in personal discussions. Distance learning can be ameliorated by careful design, more interaction initiatives, creative methods to enhance learning and availability of timely technical support. Future research should be conducted in a larger sample.

Daily, people are being exposed to an enormous amount of Covid-19 information, but not all of it is reliable. This phenomenon seriously affects the public health policy effectiveness, because there is a lot of misleading or inaccurate information, which is spreading rapidly and makes it more difficult to restrict the pandemic. Healthcare informatics has emerged as a diverse and important new field. Healthcare informatics applications are becoming more and more popular and are providing easy access to new sources of knowledge. This way, the quality of patient care will improve and productivity will increase. However, people should also learn how to navigate this infodemic properly.

Introduction: Vaccination is the best method for microbial and viral infections prevention. Especially for health professionals, flu vaccination is the best method to protect them, and the same applies for the patients and the general population from being infected. One of the most important preventive measure is vaccination and the main types of vaccines available, the limitations and side effects are briefly presented. Aim: The aim of this paper is to present the necessity of the healthcare professionals to conceptualize the importance of flu vaccination ifor themselves and the general population. Healthcare professionals are influenced by their knowledge, attitudes, and beliefs. Epidemiological surveys on this issue are presented for Greece, European Union, and the USA. Methods: A broad scope literature review was conducted based on a strict selection process of articles referring to the general population and the healthcare professionals with emphasis on the time period from the fall of 2018 until the spring of 2020 across Greece. The method used in this research obtained information through bibliographical references throughout Europe, USA, and relevant studies in Greece. Results: The results of this research indicated that influenza vaccination among healthcare professionals in Greece in the time period 2018-2019 was higher in primary health centers (PHCs) with a percentage of 43.8% than in Hospitals which was 30.6%. In addition, in the time period 2019-2020 flu vaccination among health professionals was higher in PHCs with a percentage of 57.9% rather than in Hospitals with a percentage of 38.8%. Specifically, flu vaccination rate which took place in hospitals was higher among physicians than in other healthcare personnel. Furthermore, the fundamental reasons for recommending flu vaccination in healthcare professionals are presented, and issues related to denial or acceptance of it are highlighted. Measures and strategies are proposed in order to increase flu vaccination coverage in healthcare facilities in Greece. Conclusions: Based on this research review healthcare professionals (HCPs) especially the ones working in ICUs, in ICUs for newborn children, in Departments for acute care infections, in Departments caring of persons with immunodeficiency or Units for transplantation, Oncology and Haematology Departments, and finally, in Emergency Care Units need directly to be vaccinated for the flu virus. Different measures have been undertaken to promote flu vaccination and the percentage of implementation has been highlighted.

The aim of this work is to shortly provide the public with an overview about fake news and artificial intelligence (AI) technology. Especially in our days, where there is a high speed of spreading news, the impact of fake news on public health is crucial and the development of valid and effective means of technology to support the provision of safe and trustworthy information about public health issues is vital. The role of informatics in health area is profoundly important and AI in public health, so people will be able to distinguish the genuine information from the fake one.
