The Minister for Health, Osagie Ehanire, has said about 27 states of the federation have recorded cases of Lassa fever as at the last count.
Mr Ehanire said this during a meeting with state health commissioners across the 36 states, at a two-day event organised by the Nigerian Governors Forum in Abuja.
He also disclosed that progress is being made by the federal government on developing a vaccine against the disease in partnership with a German research firm.
The 36 state governors, under the aegis of the forum, said in January that state governments are partnering with other health agencies to tackle the epidemic.
At least 16 people have so far died in a fresh outbreak of the disease in Ondo State, and about 84 cases have also been recorded since the beginning of the year.
In Kano State, the outbreak has killed three victims, including a pregnant woman and two medical doctors, after they were diagnosed at the Aminu Kano Teaching Hospital.
