AI Article Synopsis

  • Lassa virus (LASV) is a significant pathogen in West Africa, primarily spread by infected rodents and can cause serious illness known as Lassa fever, which has high morbidity and mortality rates.
  • Recent studies show that LASV is expanding beyond its typical regions, prompting global health organizations like WHO and the FDA to prioritize vaccine development and therapeutic measures against it.
  • The article discusses advancements in LASV vaccine research, emphasizing how the virus’s genetic and biological diversity influences the creation of effective vaccine candidates that align with WHO standards.

Article Abstract

Lassa virus (LASV) is a highly prevalent mammarenavirus in West Africa and is maintained in nature in a persistently infected rodent host, , which is widely spread in sub-Saharan Africa. LASV infection of humans can cause Lassa fever (LF), a disease associated with high morbidity and significant mortality. Recent evidence indicates an LASV expansion outside its traditional endemic areas. In 2017, the World Health Organization (WHO) included LASV in top-priority pathogens and released a Target Product Profile (TPP) for vaccine development. Likewise, in 2018, the US Food and Drug Administration added LF to a priority review voucher program to encourage the development of preventive and therapeutics measures. In this article, we review recent progress in LASV vaccine research and development with a focus on the impact of LASV genetic and biological diversity on the design and development of vaccine candidates meeting the WHO's TPP for an LASV vaccine.

Objectives: Lassa fever (LF) poses a significant health burden in West Africa. The pathophysiology of LF and determinants of clinical spectrum of disease remain poorly understood. We performed a study to understand the correlation of blood inflammatory marker C-reactive protein (CRP), with LF disease severity.

Background: Dengue fever (DF) poses a growing global threat, necessitating a comprehensive one-health approach to address its complex interplay between human, animal, and environmental factors. In Oyo State, Nigeria, the true burden of DF remains unknown due to underdiagnosis and misdiagnosis as malaria, exacerbated by poor health-seeking behavior, weak surveillance systems, and inadequate health infrastructure. Adopting a one-health approach is crucial to understanding the dynamics of DF transmission.

Lassa fever (LF), a viral hemorrhagic fever disease with a case fatality rate that can be over 20% among hospitalized LF patients, is endemic to many West African countries. Currently, no vaccines or therapies are specifically licensed to prevent or treat LF, hence the significance of developing therapeutics against the mammarenavirus Lassa virus (LASV), the causative agent of LF. We used in silico docking approaches to investigate the binding affinities of 2015 existing drugs to LASV proteins known to play critical roles in the formation and activity of the virus ribonucleoprotein complex (vRNP) responsible for directing replication and transcription of the viral genome.

Background and objective Viral infections caused by cytomegalovirus, lymphocytic choriomeningitis virus, varicella-zoster virus, herpes simplex type 1 and type 2, rubella, measles, rubeola, HIV, West Nile virus, Lassa virus, and mumps are known to be associated with hearing loss. There have been reports of inner ear involvement in coronavirus disease 2019 (COVID-19) patients but the extent and variations in cochlear involvement of symptomatic and asymptomatic patients has not been adequately described. This study aimed to evaluate the hearing status among symptomatic and asymptomatic COVID-19 patients to address the prospects for routine screening for hearing loss in COVID-19 patients.

Lassa virus genome consists of two single-stranded, negative-sense RNA segments that lie in the genus Arenavirus. The disease associated with the Lassa virus is distributed all over the world, with approximately 3,000,000-5,000,000 infections diagnosed annually in West Africa. It shows high health risks to the human being.
