[Analysis of the occurrence of intestinal parasites among children in first grade in elementary school in Poland in the school year 1992/3].
In 1992/93 there were reexamined in Poland 10% of the population of children aged 7 years for the presence of intestinal parasites, continuing country-wide operation launched in 1988. The examination included 60,288 children, 38,003 inhabiting towns and 22,285 from the country. Among the examined in each voivodeship 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, decantation and cellophane swabs according to NIH. The parasites encountered in order of decreasing frequency comprised: E. vermicularis, G. intestinalis, Entamoeba coli, A. lumbricoides and T. trichiura. The highest number of infected children was found in the Biała Podlaska district. The number of infected among children inhabiting country was significantly higher than among those from the towns. The obtained results have confirmed hitherto existing views that in Poland the epidemiological situation of infections with intestinal parasites is steadily improving.
