The article consists in an account of the numbers of reported cases of infectious diseases among approximately 10,000 refugees who came to the Stockholm area, primarily from the former Yugoslavia, Africa, Asia and Irak during the period 1992-1993. High prevalences were noted of hepatitis B and tuberculosis, and in certain groups high prevalences of HIV. Hitherto there has been no increase in the spread of infections to the general population. In the event of a wave of refugees from Russia and the Baltic countries, it is primarily diphtheria and tuberculosis that will entail vigilance.
