For agents of disease and their vectors to suddenly occur at places which were thought to be safe. Thus, it is not astonishing that worldwide so-called emerging diseases occur at a formerly unbelievable speed.

Therefore, it is needed to observe intensively the development and progress of such aggressive organisms.
