This new directive is to take effect by midnight of Tuesday, a member of the Presidential Steering Committee (PSC) on COVID-19, Dr Mukhtar Mohammed, declared.
Mohammed, who is the Head of Technical Secretariat of the PSC, made the announcement while briefing reporters on Monday in Abuja.
With the lockdown imposed, mass gatherings in public spaces have been restricted to 50 people at any given time.
Access to government institutions would also be denied to anyone not wearing a face mask while government meetings and travels have been limited to the virtual platform.
According to Mohammed, the government has directed that bars and nightclubs should remain closed and the nationwide curfew will be in force until further notice.
He added that only essential international travels would be encouraged, and all existing protocols must be strictly adhered to.
The PSC member, however, stated that there was no limitation to intra-state travel.
