Ultra-Orthodox communities in Israel have been more affected by the COVID-19 pandemic than other segments of the Israeli population. A variety of reasons might be responsible for this. Professor Yossi David of the Department of Communication of Johannes Gutenberg University Mainz (JGU) is investigating, among other things, the role of digital media in the health and safety practices of these religious communities. As evidenced by the study now published, using new media can make a significant difference in improving compliance with government health guidelines. The study is based on a representative survey of 500 ultra-Orthodox Israeli adults conducted during the second COVID-19 wave in the fall of 2020, i.e., before vaccinations were available.
