We publish a new open access article "The Evolution of African Swine Fever in China: A Global Threat?" in the journal Frontiers in Veterinary Science.
Abstract: African swine fever (ASF) is one of the most critical diseases in the pig industry. In Asia, 15 countries have already reported an outbreak as of November 22, 2021. In 2021, China reported the genotype II lower virulent ASF virus (ASFV) and the emergence of genotype I ASFV. ASF is generally known as a contagious and lethal disease, but if chronic infection spreads, then disease control would be more difficult. In the current study, we highlighted the possibility of lower virulent virus distribution throughout China and the subsequent general risk of the virus being released from the country. The kernel density estimation showed that the two highest kernel density areas of ASF notification were located in Northeast and Midwest China. Four of the five provinces where lower virulent ASFV was isolated overlapped with areas of relatively high ASF notification density. In terms of the risk of ASFV spreading from China, eight of the 10 largest airports and three of the 10 largest seaports are located in areas of relatively high ASF notification density. There were flight flow from China to 67 countries and ship flow to 81 countries. Asia had the highest flight flow, followed by Europe, North America, Africa, and Oceania. The highest number of ship flows was also concentrated in Asia, but about 10% of ships head to Africa and South America. Chinese overseas residents were distributed in each continent in proportion to these results. Here, we highlight the potential risk of ASFV spread from China to the world.

New article in the Veterinary Research Communications jorunal: "Evaluation of the clinical evolution and transmission of SARS-CoV-2 infection in cats by simulating natural routes of infection".
Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the current pandemic disease denominated as Coronavirus Disease 2019 (COVID-19). Several studies suggest that the original source of this virus was a spillover from an animal reservoir and its subsequent adaptation to humans. Of all the different animals affected, cats are one of the most susceptible species. Moreover, several cases of natural infection in domestic and stray cats have been reported in the last few months. Although experimental infection assays have demonstrated that cats are successfully infected and can transmit the virus to other cats by aerosol, the conditions used for these experiments have not been specified in terms of ventilation. We have, therefore, evaluated the susceptibility of cats using routes of infection similar to those expected under natural conditions (exposure to a sneeze, cough, or contaminated environment) by aerosol and oral infection. We have also evaluated the transmission capacity among infected and naïve cats using different air exchange levels. Despite being infected using natural routes and shed virus for a long period, the cats did not transmit the virus to contact cats when air renovation features were employed. The infected animals also developed gross and histological lesions in several organs. These outcomes confirm that cats are at risk of infection when exposed to infected people, but do not transmit the virus to other cats with high rates of air renovation.

March 15 in Vic Barcelona.
Professor José Manuel Sánchez-Vizcaíno will give a talk entitled "Immunization against African Swine Fever".
Animal´s Health news.
The EU H2020 project VACDIVA «A safe diva vaccine for African Swine Fever control and eradication» invites you to participate in this meeting. The seminar will be held On-line 8th February 2022, 09:30-14:00 CET.
We will review the global risk situation and the advances in the development of a safe, effective and DIVA vaccine. The meeting will aim at updating the situation around African Swine Fever, presenting the objectives and results already obtained through the VACDIVA project but will also include different presentations and discussions on three main topics:
- Effective and safe vaccines against African Swine Fever in wild boar and domestic pigs.
- DIVA tests to accompany vaccine candidates.
- African Swine Fever control and eradication strategies for different epidemiological scenarios in the world & Pilot Vaccine test in real environment.
