Nosocomial outbreak of Lassa fever in Conakry, Guinea, 2022

Key Points

This research investigates the transmission dynamics of Lassa fever in healthcare settings in low-prevalence areas.
Capacity building programs for viral hemorrhagic fevers were implemented.
Rapid diagnosis and genomic analysis were utilized for tracking the virus.
Ecological assessments were conducted to support control measures.
The outbreak was effectively controlled due to early intervention.
Community response strategies significantly reduced new cases of Lassa fever.
Genomic analysis pinpointed the virus's strains responsible for transmission.

Abstract

This outbreak highlights the vulnerability of healthcare settings in low-prevalence areas of West Africa to nosocomial Lassa virus transmission due to human mobility. Facilitated by capacity building programs for viral hemorrhagic fevers, rapid diagnosis, genomic analysis, and ecological assessment enabled an efficient outbreak response and control.
