In Argentina, Trichinella infection in pigs is endemic. The first report of human trichinellosis in Argentina was from 1898 in Buenos Aires. The number of human cases increased from 908, between 1971 and 1981, to 6,919, between 1990 and 2002. In pigs slaughtered in official establishments, the prevalence of Trichinella infection was 0.46% in 1914 and 0.01--0.03% during the period 1990--2004. T. spiralis is typically found in the domestic cycle that includes pigs, humans and rodents. Trichinella spp. from a sylvatic cycle has also caused human outbreaks resulting from the consumption of meat from puma, armadillo and wild boar. European migration to Argentina (principally Spanish and Italian) during the first years of the 20th century brought the tradition of preparing and eating raw sausages. This increased the risk of human exposure to Trichinella. Detection in pigs was initially made at slaughter by compression of muscle tissue (trichinoscopy) and continued this way until 1996, when artificial digestion was adopted for use in preventing human trichinellosis in Argentina. The following report synopsizes the evolution of trichinellosis in Argentina over the past century.
在阿根廷，猪的旋毛虫感染呈地方性流行。阿根廷首例人体旋毛虫病报告于1898年出自布宜诺斯艾利斯。人体病例数量从1971年至1981年期间的908例增加到1990年至2002年期间的6919例。在官方屠宰场宰杀的猪中，1914年旋毛虫感染率为0.46%，1990年至2004年期间为0.01%至0.03%。旋毛形线虫通常存在于包括猪、人和啮齿动物在内的家养循环中。来自野生动物循环的旋毛虫属也因食用美洲狮、犰狳和野猪的肉而导致人体发病。20世纪初欧洲向阿根廷的移民（主要是西班牙人和意大利人）带来了制作和食用生香肠的传统。这增加了人类接触旋毛虫的风险。最初在猪屠宰时通过挤压肌肉组织（旋毛虫镜检）进行检测，这种方式一直持续到1996年，当时阿根廷采用人工消化法来预防人体旋毛虫病。以下报告概述了阿根廷过去一个世纪旋毛虫病的发展情况。
