    Lassa virus (LASV) causes Lassa fever, a severe disease with a high case-fatality rate, posing a significant public health threat in endemic regions.

  • 2

    A novel guinea pig model was developed to study Lassa fever, allowing for lethal infection with the LASV strain LF2384 without host-virus adaptation.

  • 3

    The study compared immune responses between LASV strains LF2384 and LF2350, revealing critical pathogenic differences linked to the L protein.

  • 4

    Understanding LASV pathogenicity is essential for developing effective preventive and therapeutic strategies against Lassa fever.

  • 5

    Research involving LASV was conducted in biosafety level 4 facilities, highlighting the logistical challenges of studying high-risk pathogens.
