Knowledge, attitudes, and practices of 50 patients with surgically treated cystic echinococcosis from Basrah Province, Iraq

Cystic echinococcosis (CE) is recognised worldwide as a neglected disease of public health concern, particularly in low- and middle-income countries. The objectives of this study were to describe, using a questionnaire survey, the characteristics, attitudes, knowledge, and practices of patients with CE from Basrah Province, Iraq. We interviewed 50 patients, 31 female and 19 male, of whom, 74% originated from rural areas. Approximately half (48%) of the participants reported slaughtering livestock at home for their families’ consumption; 78% indicated the presence of a large number of stray dogs roaming freely about their village; 86% reported that they never boiled water prior to drinking it; and 26% reported not washing vegetables prior to eating them. Although a large proportion of the participants (72%) had heard of hydatid disease prior to becoming ill, over half (57%) were not aware how the disease was transmitted from animals to humans. This study highlighted a gap in health education efforts regarding CE in Southern Iraq, with a lack of counselling of patients on how to prevent reinfection. An intensive control programme should be implemented and founded on health education to reduce CE disease in Basrah

Cystic echinococcosis in marketed offal of sheep in Basrah, Iraq: Abattoir-based survey and a probabilistic model estimation of the direct economic losses due to hydatid cyst

Cystic echinococcosis (CE) is a highly endemic parasitic zoonosis in Iraq with substantial impacts on livestock productivity and human health. The objectives of this study were to study the abattoir-based occurrence of CE in marketed offal of sheep in Basrah province, Iraq, and to estimate, using a probabilistic modelling approach, the direct economic losses due to hydatid cysts. Based on detailed visual meat inspection, results from an active abattoir survey in this study revealed detection of hydatid cysts in 7.3% (95% CI: 5.4; 9.6) of 631 examined sheep carcasses. Post-mortem lesions of hydatid cyst were concurrently present in livers and lungs of more than half (54.3% (25/46)) of the positive sheep. Direct economic losses due to hydatid cysts in marketed offal were estimated using data from government reports, the one abattoir survey completed in this study, and expert opinions of local veterinarians and butchers. A Monte-Carlo simulation model was developed in a spreadsheet utilizing Latin Hypercube sampling to account for uncertainty in the input parameters. The model estimated that the average annual economic losses associated with hydatid cysts in the liver and lungs of sheep marketed for human consumption in Basrah to be US$72,470 (90% Confidence Interval (CI); ±11,302). The mean proportion of annual losses in meat products value (carcasses and offal) due to hydatid cysts in the liver and lungs of sheep marketed in Basrah province was estimated as 0.42% (90% CI; ±0.21). These estimates suggest that CE is responsible for considerable livestock-associated monetary losses in the south of Iraq. These findings can be used to inform different regional CE control program options in Iraq

A retrospective study of human cystic echinococcosis in Basrah province, Iraq

Human cystic echinococcosis (CE) is a parasitic zoonosis with serious clinical burden and constitutes a challenge to public health in endemic areas worldwide. We performed a retrospective study to investigate the occurrence of CE in patients at six hospitals in Basrah province, Iraq. In the current study setting, data retrieval and validation of the quality of hospital records was very challenging considering the difficult situation Iraq is unfortunately facing. Hospitalization records were reviewed from January 2005 to December 2015. A total of 748 cases of human with CE were diagnosed and operated in Basrah hospitals, equivalent to an annual clinical incidence of approximately 4.5 cases per 100 000 people. Hospital records show that, cystic echinococcosis affected more females (61.2%) than males (38.8%). Descriptive review of recorded CE cases in the surveyed hospitals revealed that more cases were reported in the age group of 21–30 years than in the other age groups. Based on the reviewed recorded clinical reports, cysts were mainly found in the liver (46.3%) and lungs (28.1%) of the patients. Hospital reports demonstrate that females had more hepatic cysts (63.9%) than males (36.1%). This study found that CE continues to pose a threat to public health in Basrah, and there is a need for more epidemiological investigations of CE in humans in order to determine risk factors and the economic impact of the disease in this province of Iraq
