Summary

Dirofilaria repens, a parasite typically found in pets, is increasingly causing human infections in Hungary. Six recent cases highlight the need for greater physician awareness of this zoonotic filariosis.

Area of Science:

  • Veterinary Parasitology
  • Human Infectious Diseases
  • Medical Entomology

Background:

  • Dirofilaria repens is a filaroid nematode transmitted by mosquitoes, commonly found in the subcutaneous tissues of dogs and cats in temperate regions.
  • Accidental human infections can occur, often remaining undiagnosed due to limited physician awareness of the parasite.

Observation:

  • Six new cases of Dirofilaria repens infection were identified in Hungary within the last two years.
  • These infections presented in various locations, with five cases localized in the skin and one involving deeper tissues.
  • Two cases were potentially acquired during travel to Italy, while four were considered autochthonous (local) infections.

Findings:

  • Histological examination is crucial for diagnosing Dirofilaria repens, utilizing features such as cuticle thickness, body diameter, and surface ridge characteristics.

  • The study identified six human infections, a significant number within the Hungarian medical literature, with five being dermal and one deep tissue.

    • Implications:

    • Increased incidence suggests a potential rise in autochthonous Dirofilaria repens infections in Hungary.
    • Enhanced diagnostic awareness among healthcare professionals is critical for accurate identification and management of filariosis.
    • Understanding transmission dynamics, including travel-related and local acquisition, is vital for public health strategies against zoonotic filarial diseases.
