泰国北方旋毛虫病的流行病学可能是独特的。自1962年以来，该病几乎每年都会爆发。公共卫生部传染病控制司报告了118起离散疫情，涉及5，400名患者，其中95人死亡。流行病学调查显示，疫情大多发生在农村地区，与村民庆祝当地和传统节日有关，如北方泰国新年、婚礼或其他节日。在几乎所有的病例中，感染源都被追踪到了像野生动物一样饲养的hilltribe猪，或者野猪肉。感染通常是通过食用当地的一种名为“lahb”的菜肴获得的，这种菜肴传统上在这些庆祝活动中供应。这道受欢迎的菜由切碎的生肉混合香料和辣椒组成，几乎是生的。泰国北方旋毛虫病的常见临床症状是发热和肌痛，在摄入含有包囊旋毛虫幼虫的生肉后约两周出现。根据其对大鼠和猪的感染性和同种异型酶分型，该种似乎是旋毛虫。泰国北方旋毛虫病的传播周期主要是森林型。山地猪、野猪、黑熊和豺狼是常见的宿主。人类通过食用这些动物的生肉或未煮熟的肉而闯入了这个循环。
The epidemiology of trichinellosis in northern Thailand may be unique. Since 1962, outbreaks of the disease have occurred almost every year. The Department of Communicable Disease Control, Ministry of Public Health reported 118 discrete outbreaks of the disease, involving 5,400 patients, 95 of whom have died. Epidemiological investigations reveal that the outbreaks have occurred mostly in rural areas, associated with villagers celebrating local and traditional festivals such as the northern Thai New Year, wedding ceremonies, or other festive occasions. In almost all cases the source of infection has been traced to either hilltribe pigs, which are raised like wild animals, or to meat from wild boar. Infection is usually acquired through consumption of a local dish called "lahb," traditionally served during these festivities. This popular dish consists of raw finely chopped meat mixed with spices and chilies and is served nearly raw. Common clinical symptoms of trichinellosis in northern Thailand are fever and myalgia, presenting about two weeks after ingestion of raw meat containing encysted Trichinella larvae. Based on its infectivity for rats and pigs and on alloenzyme typing, the species appears to be Trichinella spiralis. The transmission cycle of trichinellosis in northern Thailand is primarily of a sylvatic type. Hilltribe pigs, wild boars, black bear and jackal are common reservoirs. Man intrudes into the cycle by eating the raw or under-cooked meat of these animals.
