What is avian influenza (bird flu)? Why are we concerned about bird flu outbreaks? What are the control measures in birds and animals? How do outbreaks of avian influenza spread? etc.
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.
