Current epidemiological situation
Since the 60-ties of the previous century infectious diseases are no longer the major killer. One reason for this change was the introduction of successful vaccinations of the population. Because the immunization programmes were very well accepted in the society, they had tremendous impact on the disappearance of some diseases (smallpox, poliomyelitis, diphtheria, typhoid fever). Another reason for limitation of infectious diseases in Poland was systematic improvement of the sanitary situation in post-war Poland.
