Governor Rotimi Akeredolu gave the order on Tuesday.
Last week, the state closed all schools and banned political, social and religious gatherings for 14 days.
Mr Donald Ojogo, Commissioner for Information and Orientation said only life-saving and sustaining items would be allowed.
Also prohibited, until further notice, were gatherings at clubs, beer parlours and joints.
The state executive council meeting on March 23 took all the decisions, to prevent the spread of the Coronavirus.
“Under this fresh directive, which is for a period of seven days in the first instance, only the sale of life-saving and sustaining items like food, water and medicals shall be allowed,” he said.
The governor also directed the immediate cancellation of all official engagements of the government, the commissioner said.
“This directive includes courtesy calls and other engagements already approved and scheduled prior to this time; and shall suffice for a period of 14 days in the first instance.
“Similarly, Akeredolu reiterates that the suspension of political gatherings and meetings is still in force.
“The governor seeks the co-operation and understanding of all residents in the state as he works assiduously to keep the state safe from COVID-19,” he said.
