In Nigeria, at least 24 people have been killed in five states since the recent Lassa fever outbreak at the beginning of the new year, according to officials.
Over 100 patients have also been quarantined in designated treatment centers across the country after infected with a disease caused by a virus from rodent urine.
On Friday, the National Centre for Disease Control (NCDC) said in a statement on its website that the highest casualties were recorded in southwestern Ondo state with 16 deaths. There are also 84 cases reported.
In northeast Borno State, four cases were recorded and one of them died, according to Salihu Kwaya-Bura, the state health commissioner.
Two medical doctors and a pregnant woman died of the outbreak in northwestern Kano state, the state health commissioner Aminu Tsanyawa revealed.
World Health Organisation classifies Lassa fever as an acute viral hemorrhagic illness caused by Lassa virus, an arenavirus emerging with contamination of foods by infected rodent urine.
Contact with an infected person can also spread the disease and might be more severe, warns medical experts.
Lassa fever is endemic in many African countries — including Nigeria, Niger, Ghana, Guinea, Liberia, Sierra Leone, Mali, Togo and probably the northern part of Cameroon.
