Cystic echinococcosis (CE) is a parasitic zoonotic disease with a widespread occurrence, particularly in developing countries. Known as a neglected disease, it is highly prevalent in Algeria with a significant public health concern and substantial financial losses. The objectives of this study was to explore knowledge and awareness and practice of the Algerian population regarding this disease. A cross-sectional online-based survey was conducted between July 15 and September 25, 2022 using a self-administered questionnaire targeting all Algerian people of more than 18 years of age. Out of the total respondents, 87.7% have ever heard of CE with livestock rearing connection (OR:2.550, CI 95% OR: 1.108-5.870) and educational level (OR:3.826, CI 95% OR: 1.599-9.156) as the main factors associated with the level of awareness. Regarding their knowledge, results showed dispersing notions about the disease. The majority (84.8%) were aware of the zonnotic nature of the disease while only 49.6% knew that CE is caused by parasitic disease. Also, 83.3% were knowledgeable of the role of contaminated offal in the contamination of dogs which are considered as the main source of contamination of humans (65.19%). Regarding their practices, even home slaughtering was common (92.96%), some positive attitudes were prevalent where most of the participants declared washing vegetable before consumption (97.41%) and washing their hands after touching a dog (91.11%). Also, 68.29% among the dog owners declared that deworming their pets. This study has revealed that despite the high level of awareness and some positive attitudes, the level of knowledge about CE among the Algerian public has shown some gaps related to the epidemiology of the disease. These results could be helpful for the awareness campaigns programmers in their missions through focusing their efforts on raising the level of knowledge for the items that have shown a lack of understand which will be of great importance in the strategy of CE elimination.
