Loneliness is an uncomfortable state that arises when a person notices an obstacle between their own desire for social connection and virtual situation. Loneliness poses a serious menace to the health and affects all age groups. In order to assess the possible loneliness between the participants, the survey "Impact of the COVID - 19 pandemic on the occurrence of loneliness in the population" was applied. A total of 285 participants participated in the survey, which was conducted during the months of June and July 2020 using an online survey. The results of this study indicate partial loneliness of the participants in this study, which is the result of emerging situations due to the COVID-19 pandemic. Due to the measures ordered by the Civil Protection Headquarters of the Republic of Croatia, people feel as if they have lost touch with others. Due to the fact that once a social gathering guaranteed fun and merriment, today we consider it dangerous because of the risk of infection. Due to limited freedoms of movement, people spend more time with their families, staying in nature, dedicating themselves to sports and making extensive use of social networks that are during such times the salvation of socialization. Social networks ensure connectivity without bringing a person into direct contact with others, eliminating the source of COVID-19 infection. Loneliness is a growing problem of today, which is being ignored. The task of the nurse/technician is to recognize the symptoms of loneliness in time so that they can intervene in a timely manner. The approach of the nurse/technician towards such patients is especially important because kind words and a smile are an indispensable part of the work and they positively affect a person’s mood.
