Chikungunya is not endemic in the EU/EEA and the majority of the cases are travellers infected outside of the EU/EEA. When the environmental conditions are favourable, in areas where Ae. albopictus is established, viraemic travel-related cases may generate a local transmission of the virus as demonstrated by the sporadic events of chikungunya virus transmission since 2007.

Hepatitis A cases in 2021 were at their lowest levels since EU-level hepatitis A surveillance began in 2007, while five other food and waterborne diseases are rising towards pre-pandemic levels. The information is revealed in the Annual Epidemiological Report 2021, of which six chapters are published today by ECDC.
In 2021, 30 EU/EEA countries reported 3 864 cases of hepatitis A (Table 1). The EU/EEA notification rate was 0.9 cases per 100 000 population. In 2021, both the lowest number of reported cases and the lowest notification rate were reported since the beginning of EU-level hepatitis A surveillance in 2007. The total number of hepatitis A cases reported in EU/EEA countries in 2021 represented a decrease of 65.7% and 12.3% compared to 2019 and 2020, respectively.
This issue of the CDTR covers the period 11 – 17 December 2022 and includes updates on COVID-19, diphtheria, measles, streptococcal infection, invasive meningococcal disease, poliomyelitis, influenza, mass gathering monitoring, and Ebola virus disease.
Viral hepatitis is an infection that causes inflammation of the liver. It can be caused by different viruses, including hepatitis B virus (HBV) and hepatitis C virus (HCV). Both HBV and HCV can cause acute and chronic infections and are leading causes of liver cirrhosis and hepatocellular carcinoma.
A number of European countries (including Ireland, France, the Netherlands, Sweden and the United Kingdom) indicate an increase seen during 2022, particularly since September 2022, in the number of cases of invasive Group A Streptococcus (iGAS) disease among children less than ten years of age.
