Many of Nigeria's earliest coronavirus cases were people who had history of travel to high risk countries where they contracted the disease.

There have been a few notable cases across the country of patients who made consultations for coronavirus-related symptoms in health facilities but failed to disclose their history, and unduly exposed others.

During a media briefing on Monday, April 20, 2020, Governor Sanwo-Olu said it's a serious matter and his government will make some violators scapegoats.

He said, "We have taken a decision coming out of this meeting that we're actually going to be prosecuting people.

"We're going to make three or four people scapegoats and examples because it's not only unfair, you're also risking the lives of other health workers.

"I think it's only when the full arm of the law touches a few that they'll know it's a very serious matter we're talking about."

Sanwo-Olu said his government is already working on the names of "three to four" people.

"We're going to publish and publicise such names," he said, urging people to be completely honest with healthcare workers.
