Coronavirus patient in public hospital when missiles fall

Not a simple question. First, you should know that there is no real danger from missiles. The chance that a missile will hit where you are is very small. The obligation to enter the shelters is mainly because it is a public place and one of them will most likely be hit. But the danger to a specific person is very small. Therefore, in principle, if there is a problem entering the shelter, there is definitely a reason not to enter. On the other hand, you can enter the shelter and be careful with masks and keeping your distance. Therefore, I tend to think that if you can be careful enough, it is still worth entering the shelter. If it is small and there are a lot of people in it, then in my opinion it is better not to enter. The question of the financial right is irrelevant. If only you have the financial right and others do not, then of course you have the right not to let them in (I did not say that it is a mitzvah to do so, only that it is your right). But if everyone has the right, then there is no difference. At most, it can be said that others do not have the right to prevent you from entering. But if the instructions of the Ministry of Health and the Home Front Command in such a situation are not to enter, then the Dina of Malkhuta obliges you not to enter anyway. If you are diagnosed with the disease, the obligation to check whether you can be kept in a shelter is doubled, especially if there are others who are not vaccinated. Although, if someone did not get vaccinated by their own decision, you do not have to give them anything. The risk of infection is their problem. If they do not want to get infected, let them leave the shelter.
