China’s IPVS Congress with four major themes
More than 5,000 pig vets made it to Chongqing, China this year to attend the biannual International Pig Veterinary Society (IPVS) Congress, from 11-14 June. The vast majority came from China – time for a recap for those who could not make it there. Here are a few topics that jumped out.

1. ASF will reach Germany in four years According to a computerised model, African Swine Fever virus will reach wild boar populations in Germany in about four years. The virus has been a growing problem in Eastern and Middle Europe for the last decade with amongst others Russia, Ukraine and seven countries in Middle and Eastern Europe reporting the virus in wild boar. The Polish researcher Andrzej Jarynowski of the Interdiscipli- nary Research Institute in Wroclaw, Poland, introduced an early warning analysis for ASF propagation in this area of Europe. On the basis of older outbreaks he and his team wanted to predict where and when outbreaks will take place in the future. The team analysed 3,230 infection events that took place be- tween February 2014 and November 2017 and copied down time, longitude and latitude. The team concluded that the vi- ral disease spreads west at a speed of around 200 km per year. In the conclusion, Dr Jarynowski said, “Even if the epidemio- logical situation in previously affected regions could stabilise in the near future, the propagation will continue.” Dr Jarynowski, who received an award for his research during the IPVS Congress, explicitly mentioned in his presentation that ASF could be introduced to Germany’s wild boar population in four years’ time. That is excluding the role of humans, he told Pig Progress, as humans have been responsible for spreading

the ASF virus a lot quicker through Europe by irresponsibly dealing with infected meat or carcasses. Dr Jarynowski told Pig Progress as well that in his view, Europe- an authorities pay too much attention to the risk of truck driv- ers who dispose of half eaten sandwiches at the road side – and seemed to overlook the danger of migrating farm workers. In his view, farm employees pose the biggest risk for spreading ASF, having become redundant when farms shut down due to ASF. They might try their luck on farms further west, unintentionally spreading the disease.

ASF in Russia Prior to Dr Jarynowski, Prof Denis Kolbasov of the Russian Fed- eral Center for Virology and Microbiology highlighted the ASF situation in Russia in a keynote lecture, ‘Ten years with African Swine Fever – lessons learned’. One of the main messages he had for the audience was that “there is some evidence that after quite a long time (18 months) and a dramatic decrease of the wild boar subpopulations
