Two people have died in Ondo and Benue as a result of Lassa fever infection between May 18, 2020, and May 24, 2020.
According to the latest situation report published by the Nigeria Centre for Disease Control (NCDC) on Friday, May 29, the acute viral haemorrhagic illness, caused by rodents, has killed 197 people in 2020.
Nine new cases were recorded in the week under review with five in Ondo, two in Edo, and one each in Benue and Ebonyi.
Suspected cases in Aba, Bauchi, Delta, Imo, Plateau, and Taraba returned negative results.
One of the new cases recorded is a healthcare worker in Ondo State, according to the situation report.
The NCDC declared in April that the emergency phase of the 2020 Lassa fever outbreak was over because its case count dropped below levels considered to be a national emergency.
However, the agency's Director-General, Chikwe Ihekweazu, said Nigeria would continue to record Lassa fever cases even though the country had passed its usual January to April peak period.
