Challenges
Meanwhile, NCDC also highlighted the challenges in combating Lassa Fever cases in Nigeria, which include the late presentation of cases resulting in an elevated case fatality rate.
Others are poor health-seeking behaviour due to the high cost of treatment and clinical management of Lassa fever; poor environmental sanitation conditions observed in high-burden communities; and poor awareness observed in those high-burden communities
Additionally, challenges like poor environmental sanitation conditions and low awareness were also observed in high-burden communities.
