On Monday, Ehanire said although the country had not enforced isolation, it would take any step to ensure that those who were returning to Nigeria from high risk nations did not infect others.
He said some of the returnees had been hiding while also pleading with them to take the right approach.
He said, “We have not come to forced isolation, but we have had occasion to go after those who came from abroad and have not registered their presence and have not gone into self-isolation. We will publish their names until they volunteer themselves and be put under investigation.
