Evolving Pattern of Human Cystic Echinococcosis: A Cross-Sectional Study

Abstract Introduction Cystic echinococcosis (CE) poses a considerable public health challenge in many countries. Due to the absence of comprehensive CE surveillance and management guidelines and varying demographic and geographical factors across countries, examining the disease's epidemiology and clinical manifestations within specific regions is essential. The current study aims to investigate CE trends, clinical features, and patient complaints in an endemic area of Iraq. Methods This retrospective cross-sectional study was conducted at Smart Health Tower in Sulaymaniyah, Iraq, from May 2020 to May 2024. It involved patients diagnosed and treated for CE. Data was collected using detailed case forms covering patient demographics, cyst location, presentation, medical and surgical history, and recurrence. Results The study involved 605 CE patients with nearly equal gender distribution and a mean age of 40.1 ± 18.6 years. Most patients, 217(35.9%), were aged 31-50 and lived in urban areas 505(83.5%). The majority, 382(63.1%), were asymptomatic, with liver cysts being the most common 361(59.7%). Single cysts were more prevalent in 513(84.8%) cases, with surgery performed in 222(36.7%) of cases, and recurrence was rare 8(1.3%). Conclusion This study highlights a significant burden of CE in urban areas, where asymptomatic cases often lead to delayed diagnosis. The high prevalence of liver and lung cysts underscores the necessity for targeted public health strategies and enhanced control measures for free-roaming dogs.
