The commissioner said prior to their arrival in the country, the siblings and their teacher had close contact with someone infected with the virus.

Nigeria recorded her first Coronavirus case since the outbreak began in China, late February.

The first case was discovered when an Italian businessman landed in Lagos, the country's most populous city.

Barely a week after the discovery of the first case, a second case of the deadly disease was recorded.

The new coronavirus case made contact with the Italian businessman who was first diagnosed, on a Turkish Airlines flight.
