Title: Risk of African swine fever virus introduction into the United States through smuggling of pork in air passenger luggage
African swine fever causes substantial economic losses in the swine industry in affected countries. Traditionally confined to Africa with only occasional incursions into other regions, ASF began spreading into Caucasian countries and Eastern Europe in 2007, followed by Western Europe and Asia in 2018. Such a dramatic change in the global epidemiology of ASF has resulted in concerns that the disease may continue to spread into disease-free regions such as the US. In this study, we estimated the risk of introduction of ASF virus into the US through smuggling of pork in air passenger luggage. Results suggest that the mean risk of ASFV introduction into the US via this route has increased by 183.33% from the risk estimated before the disease had spread into Western Europe or Asia. Most of the risk (67.68%) was associated with flights originating from China and Hong Kong, followed by the Russian Federation (26.92%). Five US airports accounted for >90% of the risk. Results here will help to inform decisions related to the design of ASF virus surveillance strategies in the US.

African Swine Fever (ASF), the greatest threat to the swine sector worldwide, has spread to more than 55 countries on three continents and is estimated to affect more than 77% of the world's swine population.
African Swine Fever is one of the viral diseases with the greatest impact on the pig sector, as viruelt strains of the virus can cause acute or even hyperacute haemorrhagic fever in animals, with mortality of up to 100%. Due to its devastating socio-economic consequences and its effects on animal health, ASF is classified as a Notifiable Disease to the OIE.

On September 13, the Institute of Animal Science (IAS), Chinese Academy of Agricultural Sciences (CAAS), from Beijing, China visited the SUAT group led by Prof. JM Sánchez-Vizcaíno. The visit took place at VISAVET, where José Ángel Barasona and Estefanía Cadenas-Fernández (members of the group) exposed the most recent aspects of African Swine Fever.
Professor José Manuel Sánchez-Vizcaíno has a meeting with members of the China Bioscwin group to discuss both the current situation of African swine fever (ASF) globally, and the specific situation of this disease in China.
On Saturday, September 14 and 16, Professor Sánchez-Vizcaíno visited the University of Minnesota to participate as a speaker at the Allen D. Leman Swine Conference with this presentations:
- "Global situation of ASF and the different epidemiological scenarios"
- "ASF Risk Analysis in Practice"
This conference is internationally acclaimed for bringing science-driven solutions to the complex challenges facing the industry. Each year hundreds of participants from over 20 countries attend the Leman Swine Conference.

Western honey bees (Apis mellifera) are key players in crop pollination and in the maintenance of global biodiversity. Their viability is threatened by Varroa destructor, which acts as a vector of the deformed wing virus (DWV). Several genetic DWV variants have been reported, but it is unclear whether their virulence differs. We examined the prevalence of V. destructor and DWV as well as bee health in two colonies over 21 months and then characterizing DWV variants from each colony using phylogenetics. Colony H showed no signs of disease or mortality, and DWV sequence from this colony clustered with VDV/DWV-B sequences previously reported in healthy colonies. Colony W showed DWV symptoms, and DWV sequence clustered with DWV-A sequences previously reported in colonies with symptoms. These results suggest that nucleotide variations in the DWV genome can affect its virulence. Genotyping DWV variants in colonies may be an effective tool to assess risk and initiate preventive measures early.
