摘要

Introduction

The zoonotic parasite Echinococcus multilocularis emerged in Hungary in the early 2000s. During the next two decades, it continuously spread in both wildlife and the human population. The first comprehensive epidemiological study on human alveolar echinococcosis (HAE) was carried out in 2018. Then, a remarkable increase in HAE cases was detected in Hungary.

Methods

Our study aimed to identify the potential causes of trend alterations in the epidemiology of HAE. Thus, we compared the terms before (2003–2018) and after (2019–2024) the comprehensive analysis, focusing on disease outcomes and their associated background factors.

Results

We found that, during the latter study period, the prognosis of HAE improved (proportion of improving cases increased from 23.5% to 60.9%, p = 0.0006) owing to the shortening of diagnostic delay (47.1% versus 78.3% of delay within 12 months, p = 0.029), development in surgery (17.6% versus 26.1% of surgeries were R1/R2, p = 0.57) and medication (35.3% versus 73.9% of medications proved adequate, p = 0.015); however, the proportion of advanced-stage cases entering the healthcare system remained high (56.25% versus 56.52%). On the other hand, a non-significant increase in case numbers was experienced in the southwestern part of the country (11.77% versus 26.09% of all cases in Hungary).

Conclusion

We conclude that public interest arose from the first comprehensive HAE study that increased disease awareness within the healthcare system and contributed to better diagnoses and more efficient therapy. However, public awareness needs improvement, since the proportion of advanced-stage HAE did not decrease between the two study periods. Besides, the southwestern hotspot needs more attention and intervention.
