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).
Hantavirus infections are widely distributed across Europe, with the exception of some Mediterranean countries which reported a very low number of cases.
Ticks themselves do not cause disease but if a tick is infected with a virus or bacterium, then that pathogen can be transmitted through the tick’s bite and cause disease in humans.
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).
