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.
When people with infectious tuberculosis (TB) cough, sneeze or otherwise exhale droplets, they expose others to Mycobacterium tuberculosis. After a person is exposed, they can be infected with M. tuberculosis without having TB disease and without signs and symptoms. This is called latent TB infection (LTBI).
Childhood immunisation against S. pneumoniae is the most effective public health measure for preventing IPD both among vaccine recipients (direct effect), and among unimmunised populations (indirect ‘herd’ effect).
ECDC promotes the performance of external quality assessment (EQA) schemes, in which laboratories are sent simulated clinical specimens or bacterial isolates for testing by routine or reference laboratory methods. EQA schemes, or laboratory proficiency testing, provide information about the accuracy of different characterisation and typing methods as well as antimicrobial susceptibility testing (AST) and the sensitivity of the methods in place to detect a certain pathogen or novel resistance patterns.
