Identification by the working group of research objectives pertaining domain of research 4

Nr.	Research objective	Short description	Key words
1	Study on the seasonal pattern and abundance of potential vectors	The aim is to determine the possible contribution of potential vectors on the seasonality of ASF in affected areas. Different groups of vectors should be included, considering blood and non‐blood feeders.	ASF seasonality, vectors
2	Comparative study of monthly ASF herd incidence risk in 2020 between EU member states	Compare the regional monthly ASF incidence in different types of domestic pig farms in affected Member States to understand disease dynamics over time	Monthly incidence, ASF seasonality, herd incidence
3	Harmonised case–control studies in pig herds for potential seasonal risk factor involving several ASF affected countries.	Case–control studies matched on the type of pig farm. This study could focus on commercial pig farms as the number of cases in previous case–control studies was too low to reach the power needed in seasonal risk factor studies. In backyard farms, on the contrary, case–control studies have already been performed with sufficient case farms. By involving several EU MS, it is possible to get a larger sample size and thereby investigate possible risk factors in these types of farms.	ASF seasonality, risk factors
