Some governors have expressed frustration at the apparent collapse of the interstate travel ban by many commercial drivers and commuters.
They worried that this trend might increase the spread of the coronavirus and shoot up the number of COVID-19 cases.
Fresh 553 cases were recorded on Saturday in 14 states and the Federal Capital Territory.
Data from the Nigeria Centre for Disease Control showed that Lagos had 378; FCT, 52; Delta, 23; Edo, 22; Rivers, 14; and Ogun, 13.
Others were Kaduna, 12; Kano, 9; Borno, 7; and Katsina, 6. Jigawa and Oyo had 5 cases each while Yobe and Plateau had 3 cases each. Osun had 1.
With the new cases, Nigeria had 9,855 COVID-19 cases. There were 273 deaths and 2,856 recoveries.
To curb the coronavirus spread, the President, President Muhammadu Buhari (retd), had on March 30 ordered lockdown in the FCT, Lagos and Ogun states for an initial period of two weeks, followed by a three-week extension.
Several state governments introduced similar restrictions to curb the COVID-19 spread.
Buhari, however, announced a gradual easing of the lockdown from May 4, based on the recommendations of the Presidential Task Force on COVID-19.
But the President announced a nationwide curfew from 8 pm to 6 am and directed that measures such as the ban on public gatherings and non-essential interstate travel, as well as social distancing remained until further notice.
He also ordered new measures such as the compulsory wearing of face masks. Many state governors also made similar moves.
