Socio-economic factors relating to prevalence of intestinal helminthic infections were studied in 189 Thai adults residing in and around Bangkok. Questionaires were used to interview each individual about occupation, income, family occupation, family income and educational level. All participants were subjected to three microscopic stool examinations and to stool cultures for Stronglyoides stercoralis. Of 189, 34 were students (20%), 60 were unemployed (35%), and the remainder were employed in private or public sectors. The overall average personal incomes were low (less than US$ 1,000/year), while 56 per cent of them came from middle class families (US$ 2,000-4,000/year). Regarding the educational level, only 151 persons answered this question. Fourteen (9.3%) did not complete primary school; 20 (13.2%) completed primary school; 97 (64.2%) completed secondary or vocational school and 20 (13.2%) were university graduates. Prevalence of intestinal parasitic infection was 25 per cent (47/189) and 23.4 per cent (11/47) of infected individuals had multiple infections. The distribution among them was as follows: strongyloidiasis 30.5 per cent, hookworm 25.5 per cent, giardiasis 23.4 per cent, opistorchiasis 17 per cent, amoebiasis 12.8 per cent, trichuriasis 4.3 per cent, taeniasis 2 per cent and ascariasis 2 per cent. There were no statistical differences in incomes, occupations, family incomes and educational levels between infected and uninfected individuals.

The studies were carried out for six years (1980 - 1984 and in 1987) considering the frequency of invasion by A. lumbricoides and G. intestinalis in various years depending on age and sex. The clinical material involved 5948 children of either sex aged from 0 to 3 years. Ascariasis was found in 123 children (2.06%) and giardiasis in 54 cases (0.9%). The infestation was more frequent in boys and it was associated always with other diseases.

This report describes parasitic infections recorded from April 1984 to December 1987 in refugees using services of the Fort Worth-Tarrant County Public Health Department. Infections with 1,601 parasitic infections were documented in 824 laboratory specimens obtained from refugees. Ascariasis and giardiasis were more prevalent than other parasitic infections. The highest attack rates occurred in refugees from Cambodia (70.0%), Laos (69.7%), and Vietnam (54.3%). Information from this study supports published data on high attack rates and endemicity of infections in refugees from Southeast Asia. Continued surveillance and treatment of these refugees should improve their health conditions and prevent the development of endemic foci in the United States.

Stool examination from primary schoolchildren in Chiang Mai Province, north Thailand, was performed to determine the present state of parasitic infections in this area. Out of a total of 491 children, 239 proved positive (48.7%). The most common type of parasite was found to be soil-transmitted helminths such as hookworm (26.3%) or Strongyloides stercoralis (11.2%), while Ascaris lumbricoides was not so prevalent (1.2% being positive in one school out of three). These results are in contrast to earlier reports showing higher prevalence rates, leading the authors to hypothesize that improvements in sanitary conditions and eradication projects have been effective. Opisthorchiasis is another parasitic disease with a relatively high prevalence rate of 7.5%. This disease rate increases with age and it was found in two out of three schools (8.3-15.8%) and was the most common type of helminth infection. Ascariasis was not seen in these two schools, but strongyloidiasis was found to be the second most prevalent helminthiasis, having a higher infection rate than hookworm. Therefore, eradication efforts now need to be directed toward eliminating opisthorchiasis and strongyloidiasis in addition to continuing to eradicate ascariasis and hookworm infections. The most common protozoal infection with a high pathogenicity in this region was found to be giardiasis (7.7%).

A survey on intestinal parasitism was carried out by microscopic examination of stool specimens from 517 children (0 to 16 years old) or from mothers living in two rural towns in Somalia. Burao represented the hot and dry region in the north and Kismayo the more humid area in the south. The overall prevalances of intestinal parasitism were 48 and 88%, respectively. Protozoal infestation was found in 46% (potentially pathogenic protozoa in 20%) in Burao and 37% (potentially pathogenic protozoa in 17%) in Kismayo. In contrast a major difference between the two towns was observed with helminthic infection. In Burao only 6% of the specimens showed worm eggs or larvae, whereas in Kismayo the prevalence was 84% (P less than 0.001). The difference in helminthic infection rates might be explained by the different climatic factors, different population densities or habits of the people. Among 14 detected parasitoses the following five were found with an overall frequency of 10% or greater: trichuriasis (45%); entamebiasis coli (23%); ascariasis (17%); giardiasis (16%); and ancylostomiasis (15%).

A survey was conducted to assess the prevalence of intestinal parasitism in 65 native-born preschool and school-age children living in an unincorporated area of northern Florida. Fifty-seven percent of the children were found to be infected with intestinal parasites. Sixty-eight percent of males surveyed and 47% of females had either single or multiple infections. Prevalence was greatest in the five-10-year-old age group. For the total child population surveyed, parasitic infections in order of most to least prevalent were ascariasis (32%); giardiasis (29%); trichuriasis (14%); and hookworm (2%).

For the purpose of assigning priorities for research, each of the following parasitic disease is examined in regard to its affect on the nutritional status of the host: schistosomiasis, malaria, amebiasis, giardiasis, ascariasis, and hookworm. The epidemiology, diagnosis, immune response to, and available therapies for these diseases are discussed. It is suggested that highest priority be given to three diseases: hookworm, ascariasis, and schistosomiasis, because they can be treated successfully, diagnosed easily, and have a high prevalence.

One hundred fifty-nine children aged 24 to 61 months with 60% ascariasis prevalence and 21.5% giardiasis prevalence in rural Guatemala were studied prospectively for 1 yr. They were divided into four groups comparable for age, sex, socioeconomic status, and past growth experience as judged by slopes of height and weight on age. Each group was randomly assigned to the following 2-monthly treatment regimens: group I, placebo, group II, piperazine, group III, metronidazole; group IV, piperazine and metronidazole. Height and weight were measured every 3 months and stools were examined for parasites every 4 months. Piperazine administration decreased the prevalence of ascariasis to 33.8% at the end of the study but growth remained unaltered. Metronidazole administration decreased the prevalence of giardiasis to 2.5% at the end of the study and was accompanied by increased growth as judged by delta weight, delta % weight for age, slope of weight on age, delta height, delta % height for age and slope of height on age. It is suggested that failure of antiascaris treatment to enhance growth in this study may be because of 1) absence of severe malnutrition in the subjects, 2) adequacy of dietary protein, 3) possible low worm load, and 4) failure to eradicate ascariasis. The findings suggest that giardiasis is associated with reduced growth in preschool children.

In response to public concerns, 165 Meo Laotians had stools screened for intestinal parasites by the Illinois Department of Public Health. One hundred twenty-nine had at least one pathogenic parasite detected. Hookworm was detected most frequently, followed by Giardia lamblia, Trichuris trichiura, and Ascaris lumbricoides. Hookworm and overall infection were more frequent in persons 4 years of age and older, while giardiasis, ascariasis, and trichuriasis were most common in the 4- to 14-year age group. Most infections were helminthic and of no public health consequence in the United States. However, giardiasis was seven times as prevalent in refugee children as in the general US population, posing a potential public health risk in child-care settings.

When 239 (1982) and 361 (1991) five- and nine-year-old children in St. Kitts were assessed for the presence of parasitic infections, there were significant reductions in the prevalence of trichuriasis from 83% to 58%, of ascariasis from 24% to 8.6% and of giardiasis from 15% to 9.4%. Anthelminthic use, which appeared to be the most important responsible intervention tool, remained roughly at the same level at 59-51%. However, the types of anthelminthics used changed over the period. Piperazine citrate, which was used by 66% in 1982, only had 35% usage in 1991. Albendazole which was not used at all in 1982 was taken by 32% of the children in 1991 and at the same time use of laevo-tetramisole increased by 20% from 14%. Suggestions are made for an island-wide mass intervention programme to manage parasitic infections.
