Animal models of Rift Valley fever virus infection

Virus Research, 2012
Emerging and naturally occurring infectious diseases from bacterial and viral sources are constantly threatening humans and livestock. Recently, a variety of infectious diseases have emerged into previously disease-free areas, resulting in new epidemics. Consequently, governmental agencies and researchers in the area of biomedical research have started

Biodiversity of Mosquitoes (Diptera: Culicidae) in High‐Risk Areas of Mosquito‐Borne Diseases in Southeastern Iran

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Background Bam County, owing its geographical location, is one of the high‐risk areas of mosquito‐borne diseases due to its ecological, socioeconomic, and topographic characteristics, but it seems that no study has been done on the species composition and biodiversity of mosquitoes in this area, so the present study aimed at determining mosquito ...

Interepidemic Rift Valley Fever Virus Seropositivity, Northeastern Kenya

Emerging Infectious Diseases, 2008
Most outbreaks of Rift Valley fever (RVF) occur in remote locations after floods. To determine environmental risk factors and long-term sequelae of human RVF, we examined rates of previous Rift Valley fever virus (RVFV) exposure by age and location during an interepidemic period in 2006.

Transboundary Animal Diseases Associated With Cross‐Border Camel Movement. A Systematic Review and Meta‐Analysis

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Transboundary animal diseases (TADs) are contagious diseases that significantly impact livestock health, public health and economic stability. In regions with frequent cross‐border trade and transhumance involving camels, particularly the Middle East and Africa, TADs pose a heightened One Health risk due to their zoonotic potential and capacity to ...

Silent Circulation of Rift Valley Fever in Humans, Botswana, 2013–2014

Emerging Infectious Diseases, 2020
We evaluated the prevalence of Rift Valley fever virus IgG and IgM in human serum samples (n = 1,276) collected in 2013–2014 in northern Botswana. Our findings provide evidence of active circulation of this virus in humans in the absence of clinical ...

Rift Valley Fever Virus: Propagation, Quantification, and Storage

Current Protocols in Microbiology, 2019
AbstractRift Valley fever virus (RVFV) is an arthropod‐borne, zoonotic disease endemic to sub‐Saharan Africa and the Arabian Peninsula. Outbreaks of Rift Valley fever have had up to 100% mortality rates in fetal and neonatal sheep. Upon infection of ruminant and human hosts alike, RVFV infection causes an at times severe hepatitis and pathology in many

Polysaccharide Adjuvants as Innate Immune Trainers: Bridging Pattern Recognition Receptor (PRR) Activation and Metabolic Reprogramming for Synthetic Vaccine Design

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Polysaccharides modulate immune responses by engaging pattern recognition receptors (PRRs) to induce T‐cell activation. In vaccine design, their particle size critically influences lymph node targeting and activation mechanisms. By engineering structural complexity and multivalent PRR engagement, polysaccharides enable precise modulation of immune ...

143 Rift Valley fever virus

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2014
The capacity of Rift Valley fever virus (RVFV) to spread into new territories by crossing significant natural geographic barriers, re-emerge in endemic regions after long periods of silence to cause large outbreaks in human and animal populations constitute a formidable challenge for public and veterinary health authorities as well as for scientific ...

Rift Valley Fever in Small Ruminants, Senegal, 2003

Emerging Infectious Diseases, 2005
During the 2003 rainy season, the clinical and serologic incidence of Rift Valley fever was assessed in small ruminant herds living around temporary ponds located in the semi-arid region of the Ferlo, Senegal. No outbreak was detected by the surveillance
