Phylogenetic tree of 60 hepatitis A virus sequences from outbreak cases, Germany, September 2018–January 2020

The outbreak sequences cluster in hepatitis A virus (HAV) subgenotype IB and are 100% similar to sequence MH730560 from Sweden/Austria. Outbreak cases, which are highlighted in blue, were analysed by molecular typing of 460 nt of the VP1/P2A region. The six most closely related European Nt Archive (ENA) database entries were from Egyptian strawberries, stool and sewage. Typical reference members of genotype I–VII are denoted by isolate name (italics) and database ID. Genotype VII was used as an outgroup. Numbers at the nodes indicate bootstrap values of > 60%. The Sweden/Austria outbreak sequence and three additional sequences from selected food associated hepatitis A outbreaks are shown in magenta. The scale bar represents 0.07 substitutions per site.
