Avian influenza viruses (AIV) remain prevalent among wild bird populations in the European Union and European Economic Area (EU/EEA), leading to significant illness in and death of birds.
Poliovirus is highly contagious and infected individuals shed virus in the faeces and from oral secretions, thus the mode of transmission is person-to-person, both via the faecal-oral and the oral-oral routes.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 16-22 July 2023 and includes updates on avian influenza, Echovirus 11, COVID-19, West Nile virus, poliomyelitis, and botulism.
