The European Centre for Disease Prevention and Control (ECDC) has updated its technical guidelines. These guidelines aim to prevent the transmission of hepatitis B virus (HBV) and hepatitis C virus (HCV). Transmission occurs through substances of human origin, including donated blood, stem cells, reproductive cells, and tissue. The objective is to enhance patient safety during medical procedures. The guidelines establish a single, EU-wide standard. This ensures a consistent level of protection for all recipients within the European Union. Their implementation is crucial for reducing the risk of infection through donated materials. ECDC thus contributes to a safer medical environment.
