A chosson learning in a yeshiva in Bnei Braq was nervous. With his wedding day approaching and the CoronaVirus spreading, he was concerned that within two weeks of his wedding perhaps someone in his yeshiva would be discovered to be carrying the CoronaVirus and then he would have to go into quarantine and it would mess up the wedding plans.

Mr Chosson went to Rav Chaim Kanievsky to ask if he should stay in yeshiva to learn for the next couple of weeks until his wedding, or if he should go home to avoid risk of exposure until the wedding.

Rav Chaim Kanievski responded that he should go home.

I guess his family members were worried that this might be taken as instructions that people should not be in yeshiva now but should go home, they announced that this psak was individual for this chosson and should not be taken as instructions for other people or for the general public.
