Abstract

INTRODUCTION: Infections caused by parasites still represent an important global health problem. Although parasitic infections are responsible for significant morbidity and mortality in developing countries, they are also prevalent in developed countries. This study aims to establish the dynamics of the parasitic infections registered in the country (local and imported) and to analyze the situation, based on data from the previous years.

METHODS: We used the annual reports of regional health inspectorates, diagnostic laboratories, medical universities, and data from the National center of infectious and parasitic diseases about all individuals infected with parasitic diseases in the country.

RESULTS: A total of 635,522 persons were examined in 2022, of whom 1.82% were diagnosed with various parasitic infections. In the local helminthic zoonoses such as echinococcosis and trichinellosis, a significant decrease in morbidity was observed,1.3%₀₀₀ (n = 89) for cystic echinococcosis and 0.16%₀₀₀ (n = 9) for trichinellosis. For soil-transmitted helminthiases (ascariasis and trichuriasis), the incidence was 6.7%₀₀₀ and 0.5%₀₀₀, respectively. Data on enterobiasis does not show any particular dynamics in 2022 either. The registered prevalence for the country was 1.48%, and for children from various childcare facilities - 2.45%. During the year, seven cases of vector-borne parasitic diseases were registered in the country: imported malaria was diagnosed in 5 patients (4 Bulgarian citizens and one foreigner), and autochthonous visceral leishmaniasis - in two persons.

CONCLUSIONS: The analysis shows that, in spite of a trend of   declining   morbidityfor some socially significant protozoan and helminth infections, human parasitic diseases still represent a significant problem with social and medical consequences for the population of our country. Therefore, it is necessary to preserve and strengthen the surveillance and control network  by including new personnel in the medical parasitology structures.
