As of 3rd June 2022, 445 cases of monophasic Salmonella Typhimurium sequence type 34 infection had been reported globally. The outbreak was caused by two novel strains of monophasic S. Typhimurium with unusual multi-drug resistance. The majority of these cases involved children aged 10 or younger, and they had a hospitalization rate higher than most previous outbreaks of monophasic S. Typhimurium, but no fatalities were recorded. The infection was traced to certain Belgian chocolate products after extensive microbiological and epidemiological research. Public health officials took immediate action to recall all the contaminated products, and the risk of exposure was reduced. The common symptoms are bloody diarrhea, acute onset of fever, abdominal pain, and vomiting. This article aims to thoroughly review the recent outbreak of monophasic Salmonella Typhimurium ST-34, including its epidemiology and comparison with ongoing outbreaks. We also highlighted past chocolate-related salmonella outbreaks and current control and prevention guidelines and recommendations.
截至2022年6月3日，全球已报告445例单相鼠伤寒沙门氏菌序列型34感染病例。此次疫情由两株具有异常多重耐药性的新型单相鼠伤寒沙门氏菌引起。这些病例大多数涉及10岁及以下儿童，其住院率高于以往大多数单相鼠伤寒沙门氏菌疫情，但无死亡记录。经过广泛的微生物学和流行病学研究，感染源被追溯到某些比利时巧克力产品。公共卫生官员立即采取行动召回所有受污染产品，降低了接触风险。常见症状为血性腹泻、急性发热、腹痛和呕吐。本文旨在全面回顾近期单相鼠伤寒沙门氏菌ST-34疫情，包括其流行病学情况以及与正在发生的疫情进行比较。我们还重点介绍了过去与巧克力相关的沙门氏菌疫情以及当前的控制和预防指南及建议。
