A Sick Person Going to Shul
Question: If someone is sick, coughing, sneezing and is spreading germs in shul, doesn't he have an obligation to stay home?
Answer: One who infects another person with this type of illness is exempt from any fine, since this is "Gerama" – an indirect cause. The germs do not directly penetrate a person's body, but are spread throughout the room, and afterwards are breathed in by others. This is not a certain injury since it is not certain that the other person will become sick: Perhaps he will be affected or perhaps he is immune. One who infects another person in this manner is therefore exempt from paying a fine. Nevertheless, it is forbidden for a person to injure another, even indirectly, even with germs, which are like arrows. In the book "Kehillot Yaacov," the Steipler Gaon discusses similar cases, such as one who damages through witchcraft (Kehillot Yaacov, Baba Kamma #39, #44 in the new edition at the end of the chapter). Therefore, someone who is coughing and sneezing should not go to shul, but should daven on his own. For the same reason, one should not send children with infectious sicknesses to nursery school or school, unless a doctor decides that it is better for children to be infected with this illness when they are young.
Asking Someone to Remove a Used Tissue from the Table
Question: If a person wipes his nose and places the used tissue on a table on which food is going to be served, is it permissible to tell him or should one refrain so as not to embarrass him?
Answer: It is certainly forbidden to put a used tissue on the table since it disgusts another person, as it is written: "For every deed, G-d will judge, on everything which is hidden" (Kohelet 12:13). The Talmud in Chagigah (5a) says, "This is one who kills a louse in front of another person and he is disgusted by it…This is one who spits in front of another person and he is disgusted by it." "On everything" means even on a small thing. ""Which is hidden" means even if the person who is disgusted does not inform the other person what he caused, since in his eyes there was no problem in doing such a thing. Therefore, one must certainly tell him, but it must be with gentleness and wisdom, as with every instance of giving rebuke. If, however, despite this he is still hurt or insulted, this is not our responsibility, since we acted according to the law, and he placed himself in this position.
Pointing Out to Someone to Clean their Nose
Question: Is it appropriate to tell someone that his nose is not clean or is there a concern for embarrassment?
Answer: This is similar to the previous question. Again, one should act with wisdom.
Kissing the Torah by Hand
Question: Isn't it preferable to kiss the Torah with your hand, and not your mouth, during the winter since it is unclear whether the others kissing it are sick?
Answer: It appears that this is a remote concern. We therefore leave this to the discretion of each person.
Windows Open or Shut in Shul
Question: According to doctors, it is important to have windows open in order to ventilate rooms and halls. If one of the people davening says that he is cold, does he take precedence over the many when there is a danger of becoming sick because of lack of ventilation?
Answer: We follow the accepted practice of people in all of these matters, and it is forbidden to act in a way which injures another person and is difficult for him to endure (Shulchan Aruch, Choshen Mishpat 155:39 in the Rama). It therefore seems that the general rule is: In the summer, if someone wants to open the window, it is opened, even if the majority wanted it closed. In the winter, if someone wants to close the window, it is closed, even if the majority wanted it opens. However, since doctors have established that there is a need for ventilation and that cold weather does not cause the common cold, but germs do, there is a need for ventilation in every place. This rule also applies in catering halls, yeshivot, school classrooms, buses and similar places.
