The AAP chief, who was unwell throughout the day, had a prior appointment with Prime Minister Narendra Modi at his official residence.
After meeting the Prime Minister, he went straight to his Kaushambi residence, where he was supposed to have meetings, including one with the MLAs to be inducted in the cabinet, but had to cancel them because of high fever, an AAP leader said.
"He has been down with fever for the last three days. Even today after he came back, it was difficult for him to sit, so we had to cancel all the scheduled meetings," an AAP leader said.
The AAP chief also has a sore throat, which often aggravates during winter. Even during the campaigning, he had to suspend his jansabhas due to it. Kejriwal is also a diabetic.
