In October 2011, two primary cases of hepatitis A virus (HAV) infection with identical HAV genotype IB strains to those seen in other outbreaks associated with semi-dried tomatoes were reported in England. Both cases had consumed semi-dried tomatoes. Epidemiological investigations revealed two additional cases of genotype IB strains with different sequences who also reported having consumed semi-dried tomatoes. In November, five cases of HAV infection with closely related strains were identified in the Netherlands. A foodborne multiple-strain outbreak is suspected.
2011 年 10 月，英国报告了两例原发性甲型肝炎病毒（HAV）感染病例，这两例与其他与半干西红柿有关的暴发疫情中的 HAV 基因型 IB 菌株完全相同。两例患者均食用了半干西红柿。流行病学调查显示，还有另外两例基因型为 IB 株的病例，其序列不同，也报告食用了半干西红柿。11 月，荷兰发现了 5 例 HAV 感染病例，这些病例的菌株密切相关。疑似发生了一起食源性多菌株暴发疫情。
