摘要

Visceral larva migrans (VLM) is a type of toxocariasis and is among the most widespread zoonotic parasitic infections of public health importance. This study aimed to describe the structure and epidemiological trends in hospitalization of patients with VLM in Poland (2014–2023). This population-based, retrospective study utilized hospitalization records of VLM patients in Poland obtained from the Nationwide General Hospital Morbidity Study. A total of 3559 hospital discharge records were assessed. The study group consisted of 1888 males (53% of all patients) and 1671 females (47%). Patients under 20 years of age accounted for 64.8% of all hospitalizations. The mean VLM hospitalization rate was estimated at 0.93 per 100,000. Significant differences were found between mean annual hospitalization rates in 2014–2019 and 2020–2023 (1.1 vs. 0.67 per 100,000, P < 0.001). A significantly greater share of VLM-related hospitalizations was observed in rural populations compared with urban counterparts (59.6% vs. 39.8%; P < 0.001). Hospitalizations of VLM patients primarily involved individuals under 20 years of age, males, and those living in rural areas. The reported data may be useful for comparative analyses in global contexts and suggest a need to promote higher public health standards for the monitoring and prevention of toxocariasis.
