Although the presence many arthropod vectors has been documented, collective burden arbovirus infections baseline pre-existing immunity remains enigmatic. Our goal was to determine seroprevalence exposure across country using resource-sparing, multiplex immunoassay IgG responses immunodominant antigens. 532 human serum samples, from healthy adults, collected 10...

The SARS-CoV-2 pandemic ignited global efforts to rapidly develop testing, therapeutics, and vaccines. However, the rewards of these were slow reach many low- middle-income countries (LMIC) across African continent globally. Therefore, two bead-based multiplexed serological assays developed determine exposure four counties in Liberia. This study was conducted during summer 2021 on 189 samples collected throughout Grand Bassa, Bong, Margibi, Montserrado counties. Our immunoassay (MIA)...
Introduction: lassa fever (LF) is endemic in Liberia and immediately reportable. Suspected cases are confirmed at the National Public Health Reference Laboratory. However, there limited information on trend factors associated with mortality. We described epidemiological characteristics of LF determined mortality from 2016 to 2021.
Liberia is endemic to Lassa fever (LF) and has the largest reported per capita incidence of LF patients in West African region. Cases disease increased unprecedentedly 2019 2020, characterized by a geographical drift epidemiology seasonal variation occurrence. This study aims describe epidemiological clinical characteristics from 2020.A retrospective was conducted on cases confirmed at National Public Health Reference Laboratory January December 2020. Medical records were reviewed, data...
Prevention is critical in safeguarding against the spread of hepatitis B virus (HBV) infection. The knowledge, attitudes, and practices healthcare workers (HCWs) regarding disease play an important role its prevention or spread, yet this regard, data Liberia remains scarce. Hence, determining Knowledge, Attitude, Practices (KAP) level HCWs toward HBV infection becomes necessary. A descriptive cross-sectional hospital-based study was conducted among 251 at two major health facilities...
In June 2021, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases surged in Liberia. SARS-CoV-2 sequences from patients hospitalized during March-July 2021 revealed the Delta variant was Liberia early March and dominant June, irrespective of geography. Mutations deletions suggest multiple introductions.
