Rift Valley Fever : processes of emergeance and dissemination [PDF]
Risk factors of Rift Valley fever (RVF) emergence remain partially unknown [1]. RVF is endemic in the Ferlo area (northern Senegal).A serological study performed in this region in small ruminants associated with an entomological study showed that the ...

Vector competence of Aedes vexans (Meigen), Culex poicilipes (Theobald) and Cx. quinquefasciatus Say from Senegal for West and East African lineages of Rift Valley fever virus [PDF]
Background Rift Valley fever virus (RVFV; Phlebovirus, Bunyaviridae) is a mosquito–borne, zoonotic pathogen. In Senegal, RVFV was first isolated in 1974 from Aedes dalzieli (Theobald) and thereafter from Ae. fowleri (de Charmoy), Ae. ochraceus Theobald,

Bee products as alternatives in the treatment of viral infections
Abstract Medicines used in the treatment of viral infections usually reduce symptoms. There is a need to develop drugs that inhibit the viruses and do not merely relieve the symptoms. Natural bee products possess many pharmacological properties and are widely used in folk medicine. There are many studies on the antibacterial effects of bee products but

Threshold Dynamics in a Periodic Three-Patch Rift Valley Fever Virus Transmission Model
This paper investigates a three-patch Rift Valley fever virus transmission model with periodic coefficients. The basic reproduction number Ri0i=1,2,3 is calculated for the model by using the next infection operator method. The threshold conditions on the

The Pathogenesis of Rift Valley Fever
Rift Valley fever (RVF) is an emerging zoonotic disease distributed in sub-Saharan African countries and the Arabian Peninsula. The disease is caused by the Rift Valley fever virus (RVFV) of the family Bunyaviridae and the genus Phlebovirus. The virus is

Amphibian Strategies Against Attacks by Flies: Host‐Specificity and Threats
Species interactions between Diptera flies and amphibians play a significant role in tropical ecosystems, but their ecology and evolution remain understudied. This review explores the costs flies impose on amphibians, such as pathogen transmission and disruption of communication systems, and highlights the evolutionary strategies employed by both ...

Rift Valley Fever in Small Ruminants, Senegal, 2003
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

Relevance of Management Science in the One Health Paradigm
ABSTRACT The One Health paradigm recognises the interconnectedness of human, animal, and environmental health, calling for collaborative and cross‐sectoral responses to increasingly complex health threats. However, operationalising this vision requires more than biomedical or ecological knowledge.

Scientific Opinion on Rift Valley fever [PDF]
Based on a comprehensive review of literature and OIE (World Animal Health Organisation) outbreak reports, this scientific opinion reports, first, that there is no evidence that Rift Valley fever (RVF) has spread to previously uninfected countries during
