Article Synopsis
- * Overall, 29.7% of students tested positive for infection markers, with Stara Zagora students showing higher rates (33.6%) compared to Sofia students (23%).
- * Higher seropositivity was found in male students (32.8%) compared to females (16.0%), highlighting the need for improved safety protocols and infection control in veterinary training programs.
In recent years, hepatitis E virus (HEV) infection has been found to be widespread among different animal species worldwide. In Bulgaria, high HEV seropositivity was found among pigs (60.3%), wild boars (40.

The aim of the current research was to present the HEV seroprevalence among blood donors in Bulgaria. In the present study, 555 blood donors (479 males and 76 females) were enrolled from five districts in the country (Shumen, Pleven, Stara Zagora, Plovdiv, and Sofia districts).
