Because you aren't everyone else. There are lots of people that would be hit very hard and require intense hospitalization or face death if they were to get COVID-19. Furthermore, this would put a strain on medical resources if the number of patients is higher than medical capacity. Suddenly all the treatable conditions that require medical supervision become deadly because there aren't enough medical personnel and resources to treat everyone. Got in an accident requiring emergency care? Maybe you won't be able to get it now. More still, all the medical personnel who would otherwise have gotten a flu shot and been immune to its spread now have to worry about catching COVID-19 and having medical resources spread even more thin, at the worst time. You can't just think of yourself, you have an ethical duty to consider the externalities of your actions. Edit: Maybe I should point out that panicking or worrying about it does no good and that should be minimized as much as possible. However, if people are not treating it as seriously as they should, then maybe a little bit of panic and worry would be a good thing to get people into a proper state of mind about what is going to happen.
