The Ogun State Government on Friday quarantined 28 people it claimed had physical contact with the Italian diagnosed with the deadly coronavirus.
A factory located in the Ewekoro community in the state, which the unnamed Italian visited, has been shut down with government intensifying effort to locate others who had met with him.
The search is taking place simultaneously in Lagos and Ogun states as part of the strategies aimed at containing the deadly virus.
It was not clear last night how many people had physical contacts with the unnamed Italian between his arrival in Nigeria on Monday night and Thursday when he tested positive to COVID-19.
He is currently in isolation at the bio-security facility in Yaba, Lagos.
The Nigeria Centre for Disease Control (NCDC) has already deployed its rapid response teams in Lagos to deal with the situation.
Governor Dapo Abiodun of Ogun State confirmed the decision to quarantine the 28 people during a press conference in Abeokuta last night.
Government, according to him, was leaving no stone unturned to bring the situation under control.
He advised residents and visitors to be calm.
He said officials of the Federal Ministry of Health were already in the state to assist in ensuring that the situation does not get out of control.
