Molecular epidemiology of African swine fever in East Africa

Abstract: African swine fever (ASF), a hemorrhagic disease of domestic pigs, is caused by a large enveloped icosahedral arbovirus of the Asfivirus genus in the family Asfarviridae . It has a linear, covalently close-ended, double stranded DNA (dsDNA) genome, 170 – 190 kbp in size. Warthogs (Phaecochoerus aethiopicus ), bushpigs (Potamochoerus porcus ) and soft ticks of the Ornithodoros genus are natural reservoirs of ASF virus (ASFV) in Africa. Serological differentiation between field str...

ECO-EPIDEMIOLOGY OF EBOLA AND MARBURG VIRUSES UNDER A CHANGING CLIMATE IN WESTERN UGANDA

Abstract: Despite the fact that the Ebola Virus (EBOV) and Marburg Virus diseases (MARV) are well known zoonotic diseases, most of the existing studies focus on secondary infection (humanhuman transmission) and clinical treatment of the viruses often ignoring the primary source of infection. However, improving our understanding upon the interactions that promote contact among host species and identifying risky areas are important in determining EBOV and MARV transmission and subsequent contr...

Modeling the effects of information-dependent vaccination behavior on meningitis transmission

Abstract: We propose a mathematical model to investigate the effects of information–dependent vaccination behavior on meningitis transmission. The information is represented by means of information index as early proposed by d'Onofrio et al. (Theor. Popul. Biol., 2007). We perform a qualitative analysis based on stability theory, focusing to the global stability of the disease-free equilibrium (DFE) and the related transcritical bifurcation taking place at the threshold for the DFE. Finall...
