The report includes 17 new cases between October 31 and November 6, 2022.

The agency said the national Lassa fever multi-partner, multi-sectoral Technical Working Group, continues to coordinate the response activities at all levels.

Health minister Osagie Ehanire said, “It seems to have a particular pick in Edo, Ondo Ebonyi, and Bauchi states, and we are trying to find out why.”

Mr Ehanire said the country had learnt a lot in the management of Lassa fever, noting that it had set up an intensive care unit in the four states.

He added, “We have a lot of good stocks of the medicine for the treatment of Lassa fever, like Ribavirin, an antiviral drug, which has been used with success. This is what is used, and it is in good stuck.”
