Nigeria has confirmed 21 cases of monkeypox since the start of the year with one death reported, the Nigeria Centre for Disease Control (NCDC) said late on Sunday.
Monkeypox, a usually mild viral infection, is endemic in the African countries of Cameroon, Central African Republic, Democratic Republic of Congo and Nigeria.
But it has caused global alarm after more than 200 suspected and confirmed cases of the virus were detected in at least 19 countries since early May, mostly in Europe. No deaths have been reported so far.
The NCDC said out of 61 suspected cases of monkeypox reported since January, 21 had been confirmed with one death, that of a 40-year-old man. The cases were reported in nine states and the federal capital Abuja.
"Among the 21 cases reported in 2022 so far, there has been no evidence of any new or unusual transmission of the virus, nor changes in its clinical manifestation documented (including symptoms, profile and virulence)," NCDC said.
Six of the cases were detected this month, it said.
