ing and resistance to treatment are not uncommon among the other cases. The distribution of taeniosis by age between 1961 and 1970 0-9 10-14 15-19 20-29 30-39 40-49 50-59 60-69 above age not years 70 determined 9 3 4 31 28 27 16 9 2 4 2/3 The youngest patient was 12 months old and was infected by home-made minced-meat. The oldest was 80 years old; the origin of his contamination could not be discovered. It is very interesting that 2/3 of the patients were between 20 and 50 years of age. The following conclusions can be drawn from our figures: The incidence of infection is not affected by the geographical si tuation. A large number of cases came to light in Sárospatak (14), Sátoraljaújhely (7) and Sajószentpéter (il) near to Miskolc. The number of patients in Miskolc amounts 24.8% of the total for the county. It is probable, however that the present data still do not completely reflect the true territorial distribution of taeniosis. People in the countryside are shy to reveal their complaints to the doctor and consequently infections can be brought to light only by chance. This is shown by the case revealed by our screening examinations at the Szerencs Chocolate Factory. Further despite the Ministry of Health orders in force notification of infection is not always made. In Hovember 1970 we checked the case-history sheets for the last 3 years at the internal department of the hospital at Sátoraljaújhely and discovered 6 Taenia treatments that had not been reported and for which the compulsory laboratory examinations by the Public Health and Epidemiological Service were consequently not undertaken.
