Doctors have advised him complete bed rest and have taken his blood samples.
Dr Bipin Mittal, who is treating Kejriwal, said, "The Chief Minister has been administered antibiotics to contain his diarrhoea and advised complete rest."
"He will rest for the day. As the day progresses we will see. He was very keen on going to the secretariat because he has very important announcements to make. I strictly advised him against going out," Kejriwal's doctor said.
The Delhi Chief Minister has been suffering from cough and cold since last month.
Yesterday, he had cancelled his meeting with people who had come to visit him due to fever. He later made a brief appearance and sought some time to put in place a system to redress their grievances.
Kejriwal is expected to meet Jal Board officials at his residence in Kaushambi in Ghaziabad district, Aam Admi Party sources said.
After taking charge on Saturday last, Kejriwal had said that the plan to provide 750 litres of water free to every household in Delhi would be announced on Monday.
