The mosquito species Aedes albopictus, a known vector of chikungunya and dengue viruses, is establishing itself further northwards and westwards in Europe, according to the latest data.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 11-17 June 2023 and includes updates on COVID-19, West Nile virus, chikungunya and dengue, avian influenza, measles, diphtheria, cholera, echovirus, and information on the Hajj.
The Asian Tiger, Asian Bush and Yellow Fever mosquitos have made themselves at home in Europe throughout the last years, bringing with them some of the more exotic diseases, rarely seen in the EU before.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 12-18 March 2023 and includes updates on COVID-19, iatrogenic botulism, group A streptococcal infection, influenza, chikungunya and dengue, and influenza B among young people.
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.
