In the social network Facebook from April 2020 to October 2020 an online survey using the "Google Form" was conducted to study the perception of the COVID-19 pandemic by the residents of Ukraine. The study involved 550 participants residing in the Ukraine-controlled territory and the city of Kyiv. The data are as follows: the coronavirus is considered a serious danger by 33.3±2.0% of respondents and 11.6±1.4% agree with certain doubts (in total – Σ44.9±2.1%); 21.1±1.7% believe that the coronavirus is not serious and 17.3±1.6% believe that it is probably not serious (Σ38,4±2.1%). COVID-19 is recognized as a pandemic by 73.6±1.9% of respondents, of them 45.6±2.1% of respondents completely agree with this statement. Different views towards the severity of the problem show little but reliable correlation with age (rc =0,23; p<0.001), gender (rc =0,21; p<0,001) of the respondents, as well as with the size of the locality where respondents live (rc =0.30; p<0.001). It was revealed that men (47.2±3.6%), persons over 50 years of age (47.5±5.0%) and residents of small towns with a population of 3,000 to 10,0000 residents (47.7±4.3%) are more skeptical about this issue. The majority of respondents have a moderate level of epidemiological vigilance – 299 (54.4±2.1%); this means that a person emphasizes the seriousness and real threats of coronavirus infection, perceives and adheres to the adopted measures, but with certain hesitations. A high level of epidemiological vigilance characterized by confidence in the real situation and the adopted measures is found in 119 (21.6±1.8%) respondents. A low level of epidemiological vigilance is in 121 (22.0±1.8%) res­pon­dents. Only 11 people (2.0±0.6%) have the overall sum of points, which indicates the absence of epidemiological vigilance.
