The infodemic, as a phenomenon of excessive information dissemination, represents one of the key challenges of modern society. It is especially prominent with the development of digital media and social networks, which enable the rapid spread of inaccurate or false information. Disinformation and misinformation not only affect the perception of reality but also have serious consequences on social behavior and health outcomes. The aim of this paper is to explore how false information shapes people's behavior and attitudes and how it negatively affects public health, with an emphasis on the role of healthcare workers in combating this phenomenon. The methods used in the research include surveying social media users to assess their attitudes toward fact-checking and trust in various sources. The survey was conducted online through different platforms, and the responses of a total of 63 participants were analyzed. The collected data were processed using statistical methods to determine the level of media literacy and its correlation with susceptibility to disinformation. The methodological approach encompasses a quantitative analysis of the sample and the interpretation of the obtained results. The research results showed that a significant portion of respondents has a lower level of media literacy, making them susceptible to accepting and sharing inaccurate information. It was found that many respondents do not verify the accuracy of the information they consume on social media, further complicating the fight against disinformation. Additionally, the results highlight the importance of education on recognizing and verifying the reliability of information sources, especially in the context of health topics. In conclusion, the paper emphasizes the need for continuous education and raising awareness about media literacy among the general population. Highly educated nurses and technicians, who play a significant role in combating the spread of disinformation through patient education and providing accurate information, are particularly highlighted. Education on critical thinking and responsible use of information is crucial to reducing the harmful effects of the infodemic on public health.
