In 1988 there were examined in Poland 10% of the population of children aged 7 years for the presence of intestinal parasites. The examination included 61,700 children, 39,018 inhabiting towns and 22,682 from the country. Among the examined in each province the numbers of children from towns and country were proportional to the actual number of children living in the two localities. The methods included examination of direct faecal smear in 0.85% NaCl and in Lugol's iodine, zinc sulphate flotation according to Faust, decantation and cellophane swabs according to NIH. The parasites encountered in order of decreasing frequency comprised: E. vermicularis, T. trichiura, A. lumbricoides, G. intestinalis and E. coli. The highest number of infected children were found in the middle-eastern territories of Poland. The differences in numbers of infected in towns and the country were insignificant.
