The emergence of Schmallenberg virus across Culicoides communities and ecosystems in Europe

Schmallenberg virus (SBV), a novel arboviral pathogen, has emerged and spread across Europe since 2011 inflicting congenital deformities in the offspring of infected adult ruminants. Several species of Culicoides biting midges (Diptera: Ceratopogonidae) have been implicated in the transmission of SBV through studies conducted in northern Europe. In this study Culicoides from SBV outbreak areas of mainland France and Italy (Sardinia) were screened for viral RNA. The role of both C. obsoletus and the Obsoletus complex (C. obsoletus and C. scoticus) in transmission of SBV were confirmed in France and SBV was also discovered in a pool of C. nubeculosus for the first time, implicating this species as a potential vector. While collections in Sardinia were dominated by C. imicola, only relatively small quantities of SBV RNA were detected in pools of this species and conclusive evidence of its potential role in transmission is required.

E-Readiness Among Male and Female Extension Officers in North-West Province,South Africa

E-readiness, as the inclination to benefit from information technology, among other digital facilitations, was examined among 169 extension officers selected through stratified random sampling. Data were collected by a structured, face-validated questionnaire. E-readiness of extension officers was operationalized as a composite score of awareness, availability, accessibility, competencies, and importance of information and communication technology (ICT) tools. Data obtained were analyzed using means and standard deviation. Multiple linear regression was used to isolate the determinants of e-readiness for both male and female extension officers. Significant determinants of e-readiness include living in the job area (t = 2.35, p <.05), means of mobility (2.72), educational level (1.68), number of farmers covered (1.93), working experience (1.80), and age (?2.53).
