We evaluated the effects of risk factors and control policies following the highly pathogenic avian influenza (HPAI) epidemic that struck northern Italy's poultry industry in the winter of 1999-2000. The epidemic was caused by a type-A influenza virus of the H7N1 subtype, that originated from a low-pathogenic AI virus which spread among poultry farms in(More)
Emergency oral fox vaccination campaigns, targeting a recent rabies epidemic in wild foxes (Vulpes vulpes) in north-eastern Italy, were implemented twice, first in the winter of 2009 and then in the spring of 2010. Following on an unsuccessful manual bait distribution campaign, vaccine baits were aerially distributed by helicopters using a(More)
A pilot study was implemented in the Veneto Region of Italy, aimed at classifying dairy farms which produce milk to be commercialised unpasteurised on the basis of their risk of faecal contamination of milk, which is directly correlated to the probability of a foodborne pathogen, if present in the herd and eliminated through faecal excretion, to contaminate(More)
A Geographic Information System (GIS) is a very powerful and flexible software tool for effective management of spatially referenced data (e.g., geodata). Coupling database and GIS technology provides the tools for a detailed analysis of spatial patterns and distributions in veterinary applications. A specific veterinary GIS (VetGIS) toolbox was developed(More)
In 1999-2000, Italian poultry production was disrupted by an H7N1 virus subtype epidemic of highly pathogenic avian influenza (HPAI). The objectives of the present study were to identify risk factors for infection on poultry farms located in regions that had the highest number of outbreaks (Veneto and Lombardia) and the impact of pre-emptive culling as a(More)
This paper illustrates and discusses the key issues of the geographical information system (GIS) developed by the Unit of Veterinary Epidemiology of the Veneto region (CREV), defined according to user needs, spatial data (availability, accessibility and applicability), development, technical aspects, inter-institutional relationships, constraints and(More)
Fox rabies re-emerged in north-eastern Italy at the end of 2008 and circulated until early 2011. As with previous rabies epidemics, the Italian cases were linked to the epidemiological situation in adjacent regions. To obtain a comprehensive picture of the dynamics of the recent Italian epidemic, we performed a detailed evolutionary analysis of RABVs(More)
Italian poultry production was affected by several outbreaks of low-pathogenicity avian influenza (LPAI) between 2000 and 2005. Intervention measures (IM), such as stamping out of infected and suspected farms, controlled marketing, restocking bans, movement restriction, and emergency vaccination, were put into force in the most affected areas of Lombardia(More)
