Rabbi Chaim Kanievsky, 92, was diagnosed with the coronavirus at the beginning of October. He participated in a special live broadcast for the Sukkot holiday. The broadcast lasted two and half hours.

Rabbi Kanievsky sat in his sukkah and watched the Simchat Beit Hashoeva celebrations accompanied by his family. At one point he was given a gemara to peruse.

After the gemara was brought to Rabbi Kanievsky, his grandson, Yanki Kanievsky, whispered a few words to him and he opened it. Rabbi Kanievsky strained and leaned forward toward the Gemara when he suddenly collapsed. His eyes closed and he fell back into his chair.

The camera was moved immediately after Rabbi Kanievsky collapsed so as not to show the rabbi in that state. After a few moments the camera as refocused on Rabbi Kanievsky, who appeared to have recovered and was examining the gemara.

"The event continued as normal in [Rabbi Kanievsky's] presence," one participant told Arutz Sheva.

Rabbi Kanievsky's condition was defined as good last night following the Simchat Torah holiday. Prior to the holiday his condition worsened as his temperature rose.

According to the official announcement, the Rabbi's doctors explained that he is experiencing the "second and most dangerous stage of the coronavirus disease."

Prime Minister Binyamin Netanyahu wrote on his Twitter account: "I join the prayers of the masses of the people of Yisrael for the health of Rabbi Chaim Kaneivsky. Please G-d, heal him."
