Detecting disease progression from animal movement using hidden Markov models
Journal of Applied Ecology, Volume 63, Issue 3, March 2026.We demonstrate how (H)HMMs can be tailored to different epidemiological scenarios and provide a template workflow for developing and selecting Hidden Markov models to infer disease status from animal movement data. Identifying infection before mortality occurs offers a valuable early‐warning tool for population managers, reduces reliance on difficult ...

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

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

Observations on rift valley fever virus and vaccines in Egypt [PDF]
Virology Journal, 2011 Abstract Rift Valley Fever virus (RVFV, genus: Phlebovirus, family: Bunyaviridae), is an arbovirus which causes significant morbidity and mortality in animals and humans. RVFV was introduced for the first time in Egypt in 1977. In endemic areas, the insect vector control and vaccination is considering appropriate measures if applied properly ...

Characterization of Attenuated Strains of Rift Valley Fever Virus
Journal of General Virology, 1988 The wild-type ZH501 strain of Rift Valley fever (RVF) virus and two small-plaque strains (T1 and T46) derived from it were characterized by plaque size, pathogenicity for hamsters and ability to replicate in Vero cells. Additionally, a mutagenized, attenuated, large-plaque, vaccine-candidate strain of RVF virus (ZH548-M12) was also studied.
