Abstract

To present the situation of human trichinellosis in Southeast Asia in the last 20th years we analyzed outbreak data and seroprevalence studies from 2001 to 2021 for this region. We queried PubMed (https://pubmed.ncbi.nlm.nih.gov) using keywords “Trichinella”, “human” and “Southeast Asia”. In addition, we described Trichinella species circulating in this region.

In Southeast Asia, in communities eating pork, several cultural factors play important roles in the transmission of Trichinella to humans. The seroprevalences of Trichinella infection in humans are known for Laos and Vietnam to be 0–10.5% in some villages. Also, in Cambodia, Laos, Malaysia, Thailand and Vietnam relatively few human outbreaks (13) and cases (1604) have been recorded during the last 21st years. Their associated mortality rates were low (0.75%). Trichinella spiralis and T. papuae were transmitted after consumption of raw or undercooked pork from domesticated and wild pigs. T. papuae transmission was related to consumption of wild boar. In this region, trichinellosis was frequently subclinical and clinical or severe cases were sporadic and occurred more in male patients. Nevertheless, it is likely that trichinellosis is widely under-diagnosed and is an endemic disease.

2001-2021年东南亚人类旋毛虫病

为了介绍过去20年东南亚人旋毛虫病的情况，我们分析了该地区2001年至2021年的暴发数据和血清流行率研究。我们使用关键词“旋毛虫”、“人类”和“东南亚”查询PubMed (https://pubmed.ncbi.nlm.nih.gov)。此外，我们还描述了在该地区流行的旋毛虫种类。在东南亚，在吃猪肉的社区中，一些文化因素在旋毛虫向人类传播方面发挥了重要作用。已知老挝和越南一些村庄的人类旋毛虫感染血清流行率为0-10.5%。此外，在柬埔寨、老挝、马来西亚、泰国和越南，在过去21年中记录的人间暴发(13例)和病例(1604例)相对较少。其相关死亡率较低(0.75%)。旋毛虫和帕帕氏锥虫是在食用生猪肉或未煮熟的家猪和野猪猪肉后传播的。T. papuae的传播与食用野猪有关。该地区旋毛虫病多为亚临床，临床或重症病例多为散发，男性多见。然而，旋毛虫病很可能被广泛诊断不足，是一种地方病。

期刊介绍： Food and Waterborne Parasitology publishes high quality papers containing original research findings, investigative reports, and scientific proceedings on parasites which are transmitted to humans via the consumption of food or water. The relevant parasites include protozoa, nematodes, cestodes and trematodes which are transmitted by food or water and capable of infecting humans. Pertinent food includes products of animal or plant origin which are domestic or wild, and consumed by humans. Animals and plants from both terrestrial and aquatic sources are included, as well as studies related to potable and other types of water which serve to harbor, perpetuate or disseminate food and waterborne parasites. Studies dealing with prevalence, transmission, epidemiology, risk assessment and mitigation, including control measures and test methodologies for parasites in food and water are of particular interest. Evidence of the emergence of such parasites and interactions among domestic animals, wildlife and humans are of interest. The impact of parasites on the health and welfare of humans is viewed as very important and within scope of the journal. Manuscripts with scientifically generated information on associations between food and waterborne parasitic diseases and lifestyle, culture and economies are also welcome. Studies involving animal experiments must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences.
