Recent ECDC data show that despite progress in prevention and control efforts, the hepatitis B and hepatitis C viruses (HBV and HCV) continue to pose significant public health challenges in the European Union and European Economic Area (EU/EEA).
Rotaviruses are the single most important cause of severe diarrhoeal illness in infants and young children worldwide. By the age of five years most children irrespective of socioeconomic setting will have been infected at least once. While infected, many children will be in need of medical attention due to extensive fluid loss.
Despite good access to effective antibiotics, Streptococcus pneumoniae (pneumococci) is still a major cause of disease and death in both developing and developed countries. Pneumococci are the main cause of bacterial respiratory tract infections, such as pneumonia, middle ear infection, and sinusitis, in all age groups.
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.
Haemophilus influenzae type b (Hib) is an obligate human pathogen and an important cause of invasive bacterial infections in both children and adults, with the highest incidence among young children.
Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.

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.
