NCDC Reports Rising Lassa Fever Cases
The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed 1,018 cases of Lassa fever out of 8,411 suspected cases reported across the country from January 1 to September 29, 2024. The cases were recorded in 28 states, affecting 128 local government areas. The outbreak has led to 172 deaths, with a Case Fatality Rate (CFR) of 16.9%, according to a report obtained from the NCDC on Friday.
Major Impact in Ondo, Edo, and Bauchi States
The NCDC highlighted that Ondo, Edo, and Bauchi states account for 68% of all confirmed Lassa fever cases. Ondo alone recorded 28% of the cases, followed by Edo with 23%, and Bauchi with 17%. The disease predominantly affects people between the ages of 31 and 40, with a near-equal ratio of male-to-female infections. Despite ongoing efforts, the number of suspected cases in 2024 has surpassed those reported during the same period in 2023.
WHO Raises Awareness of Lassa Fever Spread
Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus, which is endemic in West Africa. The World Health Organisation (WHO) has warned that the disease is primarily spread through contact with food or household items contaminated by the urine or faeces of infected Mastomys rats. Person-to-person transmission can also occur, especially in healthcare settings lacking adequate infection control measures.
Increase in Confirmed Cases in Week 39
The NCDC report revealed a rise in confirmed cases during week 39, with nine new cases reported, compared to four in the previous week. These cases were detected in Ondo and Edo states. Despite the increase, no healthcare workers were affected during the reporting period. The multi-sectoral technical working group, which includes various partners, continues to coordinate the response efforts across Nigeria.
Cumulative Death Toll for 2024
A total of 172 deaths have been reported in 2024, with a CFR of 16.9%, which is slightly higher than the 16.8% recorded during the same period in 2023. This raises concerns about the ongoing spread of the disease, particularly in endemic areas where Lassa fever continues to thrive.
Ongoing Response Efforts
The NCDC and other national health agencies remain vigilant in their efforts to contain the outbreak. Response activities continue across the affected states, with a focus on raising public awareness, improving infection control in healthcare facilities, and ensuring early detection and treatment of new cases.
