    Cysticercosis is a major zoonotic disease in many developing countries leading to substantial economic and public health impacts on affected communities.

    Due to a lack of updated data on T. solium cysticercosis in Burundi, the present study was carried out to determine the prevalence of porcine cysticercosis and to identify potential associated risk factors in Ngozi province. This study was conducted in Ngozi and Marangara communes of Ngozi province during January and February 2020. A multistage random sampling strategy was used. Tongue palpation was performed on pigs to diagnose cysticercosis. Randomly selected heads of pig keeping households were interviewed to assess the risk factors for porcine cysticercosis. A logistic regression model was used to analyse the main risk factors associated with porcine cysticercosis.

    In total, 496 pigs from 321 households distributed in 16 hills, randomly selected in Ngozi and Marangara communes were inspected. The apparent prevalence by tongue palpation in Ngozi province was 15.5% (95% CI: 12.3-18.7%). In Ngozi and in Marangara communes, the prevalence was 22.9% (95% CI: 17.7-28.2%) and 8.1% (95% CI: 4.6-11.4%), respectively. The true prevalence was estimated at 31% for the province, with a prevalence of 45.8% in Ngozi and 16.2% in Marangara commune, respectively. Pig farming systems including free ranging, tethering and penned part of the day (OR = 3.5; 95% CI: 2.1-6.1; p = 0.001) and lack of meat inspection at home slaughter (OR = 2.5; 95% CI: 1.1-5.6; p

    The present findings show that porcine cysticercosis is highly endemic in Ngozi province and that pig management systems currently used in the area permit pigs to have access to human stool. Moreover, lack of meat inspection during home slaughter potentially gives the possibility for household and community members to eat infected pork. Total confinement of pigs, improved hygiene and sanitation in households, and improvement of meat inspection through awareness campaigns and overall health education of the community should be implemented to control T. solium infections.
