Session III - FAST Update
Peste des petits ruminants (PPR) and Rift Valley Fever are examples of transboundary animal diseases having major consequences in terms of health and economics. PPR is a highly pathogenic viral disease infecting principally sheep and goats, but also some wild artiodactyls, camelids and suids. This disease circulates in large parts of Africa, Asia, Eurasia and Middle-East and it has recently appeared at the gates of Europe in Georgia (2016) and Bulgaria (2018). A vaccine sxiste and the disease is the target of an eradication campaign by 2030. RVF is an arbovirus also affecting small ruminants and camelids, but also cattle and can be transmitted to human. The virus is transmitted among ruminants through the bite of infected mosquitoes (belonging to the Aedes and Culex species) and to human through the direct contact with infected blood or tissues. The disease circulates mostly in most countries in North, East, West and Sahelian Africa as well as in the Arabian Peninsula. Despite the different way of transmission, transboundary animal movement is the most likely route of the spread of the two diseases. Even though the livestock trade is strictly regulated between endemic regions of the two diseases and most of the Mediterranean countries, regional, locally adapted strategies are needed to control the diseases efficiently. The aim of this talk is to provide a panorama of the epidemiological situation around Europe and provide some preliminary scenario for the introduction of the diseases, through animal movement, and risk of transmission due to the presence of competent vectors (only for Rift Valley Fever).

  1. 1. EuFMD OS22 Peste des petits ruminants (PPR) and Rift Valley Fever (RVF) events 2020-2022 and risk of introduction in Europe A.Apolloni1*, A.Bataille1, V. Chevalier1 CIRAD
  2. 2. #OS22 Digitalization and innovation applied to the prevention and control of foot-and-mouth and similar transboundary animal diseases (FAST) OS22 2 ● Peste des Petits Ruminants (PPR): highly pathogenic viral disease ● Hosts: sheep and goats, but also some wild artiodactyls, camelids and suids. ● Direct Transmission ● Mobility main driver for virus dissemination ● Present in Northern , Sahelian Afraca, Middle East ● EU: appearance in Bulgaria in 2018 ● UN Commtrade data: reconstruct livestock network Presenter name Short title for presentation PPR declaration 2020-2022 WAHIS
  3. 3. #OS22 Digitalization and innovation applied to the prevention and control of foot-and-mouth and similar transboundary animal diseases (FAST) OS22 3 ● Rift Valley Fever(RVF): arbovirus ● Hosts: small and large ruminants ● Can be transmitted to human. ● Transmission: ● ruminants through the bite of infected mosquitoes (belonging to the Aedes and Culex species) ● to human through the direct contact with infected blood or tissues. ● Presence in most countries in North, East, West and Sahelian Africa as well as in the Arabian Peninsula. ● No appearance in EU ● Vector competency in Mediterranean areas ● UN Commtrade data: reconstruct livestock network Presenter name Short title for presentation RVF declaration 2020-2022 WAHIS
  4. 4. #OS22 Conclusion Presenter name Short title for presentation Andrea Apolloni PPR and RVF 2020-2022 • Except for the case of Bulgarai , the diseases have not yet appeared in EU • In the period 2020-2022 outbreaks/decalartaion in area surrounding EU directly or indirectly connected • PPR: some countries in Eurasia with poor reporting ; circulation among wildlife • RVF: circulation in sahlian areas • Thraces Area, Romania and Southern Spain possible entry area due to regulated livestock movements and wildlife • Five species of concern (Ae. Caspius, Ae. Detritus, Ae. Vexans, Cx. Pipiens, Cx. Theileri) could be involved in RVFV transmission in the Mediterranean Basin • Regional, locally adapted strategies are needed to control the disease efficiently.
