Hookworm is highly endemic to Hainan Province, an island located in the South China Sea. To investigate the prevalence and intensity of infection in the area, the village of Xiulongkan was surveyed between April and July 1998. A cross-sectional study was conducted in which fecal samples of 80% of the village residents (631 individuals) were tested for the presence of helminth eggs. Hookworm was the predominant intestinal helminth in Xiulongkan, where it was determined that 60% of those tested… 

Hookworm infection: A severe health problem in periurban community of North central, Nigeria.

The findings have suggested that the listed risk factors which play a major role in the transmission of the disease need to be taken into account when formulating sustainable control strategies for hookworm and other intestinal parasites in Nigeria and elsewhere.

Incidence and risk factors of hookworm infection in a rural community of central Thailand.

The data suggest transmission of both human and animal hookworms in this community suggest prevention and control strategies of hookworm infection should cover both human or animal infection.

Age and sex made the most important contributions to the variation in infection intensity, and the importance of aging in Necator infection reveals an emerging public health problem among the elderly population of developing countries.

Efficacy of Albendazole in Reducing Fecal Egg Counts of Soil Transmitted Helminths in School Children.

The efficacy of single dose 400 mg albendazole in the treatment of Soil transmitted helminths (STH) in school children, living in areas that were or were not part of an annual mass drug administration with albENDazole was assessed.

Intestinal helminth infections among reproductive age women in Vietnam: prevalence, co-infection and risk factors.

The findings suggest that reproductive-age women, especially rural farmers, should be included among the high priority groups for helminth control programs through mass chemotherapy and improving sanitation.

Evaluating the occurrence of schistosoma haematobium and geohelminthes infection in residents of two villages in Msambweni district of coast province, Kenya

The results of this study have shown that the problem of urinary schistosomiasis and soil transmitted helminthes persists despite the control programs and enhancement of these control programs is required.

HOOKWORM AND THREADWORM INFECTIONS AND THEIR ASSOCIATION WITH HEMOGLOBIN AND EOSINOPHIL CONCENTRATIONS IN RESIDENTS OF SALVADOR-BAHIA, BRAZIL

The hemoglobin concentration was lower in the hookworm- Infected individuals than in non-infected ones, but none of the examined patients were anemic, suggesting lack of anemia could be a consequence of the socioeconomic status of these patients.

The overall infection rate of intestinal parasites was 62.6% whereas at provincial level, the highest infection rate was recovered in Hainan, and the lowest in Heilong-jiang, and a high proportion of polyparasitism among the infected population (882,080) was revealed.
