Evaluation of infection prevention and control practices in Lassa fever treatment centers in north-central Nigeria during an ongoing Lassa fever outbreak.

Background: Outbreaks of Lassa fever (LF) in Nigeria have become more frequent, with increasing more healthcare worker infections. Prevention of infection is dependent on strict compliance to infection prevention and control (IPC) practices in treatment centres where patients are managed.

Objective: To evaluate IPC practices during an ongoing LF outbreak in the two major tertiary hospitals serving as the referral LF treatment centres in the north-central region of Nigeria.

Methods: This cross-sectional survey was carried out by the IPC subteam of the National Rapid Response Team of the Nigeria Centre for Disease Control (NCDC) deployed to Plateau State, north-central Nigeria during the 2019 LF outbreak. Information on IPC in these facilities was collected using the NCDC viral haemorrhagic fevers (VHFs) isolation and treatment facility IPC survey tool.

Results: Both treatment centres had national VHF IPC isolation guidelines and few health workers had received IPC training. In both centres, there were no clearly demarcated entry points for staff going into clinical areas after putting on personal protective equipment, and there were also no standard operating procedures in place for reporting occupational exposure of staff to infected blood or body fluids in both centres.

Discussion: The LF treatment centers located in Plateau State during the 2019 LF outbreak were not fully implementing the national VHF IPC guidelines. Periodic assessments of IPC are recommended for proper management of cases and effective control of LF in the State.
