The coronavirus is a virus, the causative agent of a disease that manifests itself withflulike symptoms. Its spreads quickly and can infect human and animal populations. In some cases, severe respiratory complications and fatal outcomes can occur. A coronavirus infectionhas a number of symptoms, the most common being: fever, headache, sorethroat, shivering, shortness of breath and breathing difficulties. I conducted research on the virus by collectingdata through a written electronic survey and used a software called Google Forms. This software isused to create questionnares, surveys and quizzes. The surveyed population wasaged 18 to over 50 in Croatia. The questions were mostly related to the coronavirus andvaccination against COVID-19. As this topic is currently relevant, my work was mostlybased on the question of why some citizens still do not want to be vaccinated, which wouldgreatly reduce the effects of this pandemic. According to the results, a larger percentage ofthe female population took part in the survey, and most respondents were aged 23-28. According to the results, the majority of citizens want to get vaccinated, while the most commoncited reason for not getting vaccinated is coercion. Most citizens believe that the bestprotection against the coronavirus is washing and disinfecting hands. Also, the majority ofcitizens believe that they are sufficiently informed about the coronavirus situation. According to the survey, most citizens were worried about how the coronavirus would affect theireveryday life and about infecting family and friends. While conducting the research, I came to the conclusion that there is still no specific treatment against the disease available, rather, itis the clinical symptoms of patients that are treated. What is also specific to this disease isthatthere are no rules on whom the virus will attack and whom it wont. When it comes to thecoronavirus, all age groups are at risk, but there is a group of people who are most likely to have more severe symptoms if they are infected. These are most often diabetics, heart diseasepatientsand patients with respiratory difficulties. As we have not yet discovered everythingaboutthis disease, we are still fighting to discover medicine and new methods that couldprevent the spread of the virus.
