Abstract
Cystic echinococcosis (CE) is a serious health problem in many countries worldwide, including in Romania, because of the high infection rates in both humans and animals. We retrospectively assessed the demographic and epidemiological features of CE in children and adults hospitalized in Western Romania between 2007-2022. Analyzed data were collected from the hospitals' medical records. This research involved 426 subjects (3-90 years): 60 (14.1%) children and 366 (85.9%) adults. A decreasing trend in the number of cases was noted during the analyzed period (p = 0.004). Multiple-organ involvement was reported in 16.7% of the children and in 6.3% of the adults (p = 0.005). The liver was the most commonly affected organ. The rate of lung involvement was higher in children (25%) than in adults (13.1%) (p = 0.02). Most of the patients had one hospital presentation (74.9%). Multiple hospitalizations were reported in 40% of the children and 22.7% of the adults (p = 0.004). CE is a severe zoonotic disease that impacts individuals of all ages. Despite the decline in cases, CE remains a public-health problem in Western Romania. Health programs that target risk factors and control measures should be implemented to stop the parasite's spread and maintain the trend toward reduced numbers of CE cases.
