The One Health Synergy Group works on issues affecting human, animal and plant health with environmental impacts. Zoonotic diseases such as rabies, avian influenza, etc. are very important. It is currently focusing intensively on the risks and impacts of antibiotic overuse. The group, in cooperation with the CZEPAR platform and the other expert institutions, is preparing materials for the worldwide campaign EAAD 2024 (European Antibiotic Awareness Day) and WAAW 2024 (World Antimicrobial Awareness Week).
