Q. I am sharing an apartment with someone that has corona in separate rooms. very late at night there was a lady nurse that came in to see him so it was two men and a lady at night. what should I do?
A. Remah (E. H. 22: 5) rules that two men are permitted to seclude themselves with one woman. This applies especially when it involves a Gentile woman, since then yichud according to many Poskim is only Rabbinical (Avoda Zarah 26a). Therefore while the nurse visits, the door between the rooms should be kept open, and if possible the door to the outside or staircase also, as well as a window to the street, if there are still some passers-by.
It is very recommended that a recording security camera should be installed.
We wrote on question 828: 'Horav Nissim Karelitz Shlita (quoted in Moriah-Elul 5771 p.146) maintains that security cameras are to be regarded as an open door to the street in regards to the yichud prohibition, which the Noda Beyihuda (E.H. 71) permits. He mentions that they do not have to be scrutinized on real time, as long as there is a possibility that the tape (or digital recording) could later be seen, and it is an effective deterrent.'
On question 2809 we wrote: 'Asking a friend that is close by, to call on you is certainly beneficial, when he can have actual access at his will. See similar question 1688 where we wrote; “The home door should be left unlocked or the meeting should take place in a room with an uncovered window facing the street.
Horav Shlomo Miller Shlit’a has advised on similar situations to take your cell phone with you and leave it with the camera on facing you, while a friend is checking on you.'
