Recently, molecular characterisation of E. suggests that the disease has extended to La Paz, Cochabamba, and Potosí. The most up-to-date map of the global distribution of Echinococcus spp. Moro and Schantz published, in 2006, the latest revision of the situation of CE in the Americas without adding new data due to the apparent lack of original publications from Bolivia. By 1995, it was believed that CE was endemic in the mountainous regions of Bolivia. Neghme also suggested (in 1987) that CE was present in Bolivia, but it was less common than in other South American countries. The only available data (at the time) indicated that 75 CE surgeries were performed in a hospital from the Altiplano region in 10 years. First, Peter Schantz in the 1970s highlighted the lack of information related to CE in Bolivia. Reviews of CE in South America have anticipated that the disease must be an important issue in Bolivia. Moreover, Bolivia is not yet an official member of the international control initiative mentioned above. In the case of Bolivia, data regarding any aspect of the epidemiology of CE are not well documented. Furthermore, these 5 countries have joined forces since 2004 in “The Regional Initiative for the Control of CE” sponsored by the Pan-American Health Organization (PAHO). Substantial research on different aspects of the epidemiology of CE in these countries has been published. l), is highly endemic in regions of Argentina, Brazil, Chile, Peru, and Uruguay. is circulating in Bolivia and that a proper prospective nationwide epidemiological study of CE is urgently needed to define transmission patterns as a basis for the planning and implementation of future control measurements.Ĭystic echinococcosis (CE), caused by Echinococcus granulosus sensu lato ( s. s.), Echinococcus ortleppi (G5), and Echinococcus intermedius (G7) have been identified in Bolivia. Finally, Echinococcus granulosus sensu stricto ( s. The highest prevalence in intermediate hosts reported at abattoir reached 37.5% in cattle from Potosí, followed by 26.9% in llamas from Oruro, 2.4% in pigs and 1.4% in sheep from La Paz. In the same report, 24% of dog faecal samples were positive for coproantigens of E. In the absence of other epidemiological studies, the highest prevalence in human comes from Tupiza, Potosí Department, where 4.1% (51/1,268) of the population showed signs of CE at mass ultrasound screening in 2011. In total, 876 human CE cases have been reported in the scientific literature, with an apparent increase since the 1970s. granulosus infection in animals dates in 1910, while the first human case was reported in 1913. We aim here to fill the gap in the current knowledge of the epidemiological situation of CE in Bolivia, providing a historical overview of documents published within the country, which have never been comprehensively reviewed. However, it is well known that CE occurs in Bolivia. For Bolivia, no official data concerning the incidence in humans or the number of livestock and dogs infected are available. CE is highly endemic in South America, including Argentina, Brazil, Chile, Uruguay, and Peru. Furthermore, CE represents a serious zoonosis causing a significant global burden of disease. l.) infect various intermediate hosts causing cystic echinococcosis (CE).
