This study is aimed to evaluate prevalence of hockworm infection in three mountainous and midland communes of BacGiang province. Results showed that general prevalence of hockworm infection in these populations was 28.7%, in farmers: 29.8%, the others: 21%. In hockworm infection people, the rate of anemia was 52.7%, no one suffered severe anemia. Anemia had bad influence to people’s health with symptoms of pale skin and mucosal lining, chronic fatigue, and dyspnea in effort

Cutaneous larva migrans(CLM) is a ubiquitous self-limiting skin eruption which has intensely pruritic, serpiginous, raised, sharply demarcated, red lesions. It is most frequently caused by larvae of dog and cat hookworms. We report two typical cases of cutaneous larva migrans that appeared as pruritic exanthems in two people after they had travelled in Southeast Asia. It is suggested one should consider cutaneous larva migrans in the differential diagnoses of erythematous pruritic lesions.

Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the transmission ecology of the site.

Cutaneous larva migrans is a characteristic serpiginous creeping eruption that is caused by the migration of the larval form of neomatodes in the skin. It is caused by hookworm larvae, which are present in the feces of infected dogs and cats. The skin lesions progressively evolve at a rate of 2~3 cm daily. Most cases have a travel history to tropical and subtropical countries, but our patient had no travel history to an endemic area and no contact history with the feces of dogs and cats. We report herein on a case of cutaneous larva migrans on the neck and the patient did not have a travel history to an endemic area and the lesions showed relatively rapid progression.

Cutaneous larva migrans (CLM) is a rare serpiginous creeping eruption caused by accidental penetration and migration in the skin with a larval form of nematodes. It is caused by hookworm larvae, which are present in the feces of infected dogs and cats. Most cases of CLM in Korea have been shown to involve travelers returning from tropical areas or hot climates. We experienced four patients who had pruritic serpiginous linear eruptions on their skin after traveling to the endemic areas (Boracay island in Philippine). After treatment with albendazole, the skin lesions resolved with post-inflammatory hyperpigmentation. We report herein these four cases, together with a literature review of CLM cases in Korea.

Adult specimens of Echinostoma ilocanum (Garrison, 1908) Odhner, 1911 (Trematoda: Echinostomatidae) were recovered from 2 riparian people who resided along the Mekong River in Savannakhet Province, Lao PDR. In fecal examinations done by the Kato-Katz technique, they revealed echinostome eggs together with eggs of Opisthorchis viverrini (and minute intestinal fluke eggs) and hookworms. To recover the adult flukes, they were treated with praziquantel 30–40 mg/kg in a single dose and purged with magnesium salts. A total of 658 adult fluke specimens were recovered from the 2 people; 456 from case 1 and 202 from case 2. Specimens from case 1 consisted of 335 echinostomes (301 E. ilocanum and 34 species undetermined), 120 O. viverrini, and 1 Haplorchis taichui, and those from case 2 consisted of 36 E. ilocanum, 134 O. viverrini, and 32 H. taichui. Thus, the number of E. ilocanum specimens was 337 in total (average per person, 168.5). From this study, it is suggested that foodborne intestinal flukes and liver flukes are highly prevalent along the Mekong River in Savannakhet Province. The present report describes for the first time human infections with E. ilocanum in Lao PDR.

With the improvement of sanitation, the infection rate of hookworm is greatly reduced and the severe infected case is rarely reported. Combined morphological and molecular biological examinations, a severe hookworm infection patient was diagnosed in Department of Laboratorial Examination, Quanzhou First Affiliated Hospital of Fujian Medical University. The morphological methods such as direct fecal smear microscopy, saturated brine flotation and hookworm larvae culture methods were used to identify the eggs and larvae from stool samples of the patient. There were a large number of hookworm eggs in patient's stool samples, and the average count was 60 840 per gram by modified Kato method, which belonged to severe hookworm infection. Meanwhile, to distinguish the hookworm species, the semi-nested RT-PCR assay was employed to detect hookworm internal transcribed spacer series from eggs in patient's stool samples, and the result showed that the hookworm species was confirmed to be Necator americanus.

Soil-transmitted helminths (STH), namely Ascaris, Trichuris and hookworms (Ancylostoma and Necator), present a global health problem to about a half of the earth's population. In the Republic of Korea, STH were highly prevalent and were considered a high priority target for national control. To promote the control, a non-governmental organization named Korea Association for Parasite Eradication (currently Korea Association of Health Promotion) was founded in 1964, and mass fecal examination followed by selective mass chemotherapy with anthelmintics was performed twice a year from 1969 to 1995 targeting whole nationwide schoolchildren. Meanwhile, decreasing patterns of national STH infections have been monitored by 7 times' quinquennial national surveys targeting general population. In 1971, the overall intestinal helminth egg positive rate was 84.3% (Ascaris 58.2%, Trichuris 65.4%, and hookworms 10.7%), which became 63.2% in 1976, 41.1% in 1981, 12.9% in 1986, 3.8% in 1992, 2.4% in 1997, and 4.3% (Ascaris 0.03%, Trichuris 0.02%, and hookworms 0%) in 2004. During the control period, national economy rapidly developed, and living standards including environment, sanitation, and agricultural technology greatly improved, which undoubtedly boosted the STH control effects. Our experience indicates that social driving force to establish an eligible national control system to conduct repeated mass chemotherapy, together with improvement of environment and sanitation, is important for initiating and achieving STH control in a developing community.

A 26-year-old male member of the Australian Defense Force presented with a history of central abdominal pain of 4 weeks duration and peripheral eosinophilia consistent with eosinophilic enteritis. Acute hookworm disease was diagnosed as the cause. Adult worms recovered from feces after therapy with albendazole were morphologically consistent with Ancylostoma ceylanicum. As the patient had been deployed with the Regional Assistance Mission to Solomon Islands for 6 months prior to this presentation, it is very likely that the A. ceylanicum was acquired in Solomon Islands. Until now, it has been assumed that any Ancylostoma spp. recovered from humans in Solomon Islands is A. duodenale. However, this case demonstrates that human hookworm infection acquired in the Solomon Islands could be caused by A. ceylanicum.

Creeping eruption is a syndrome characterized by the penetration in human skin of larvae from hookworms of various animals, mainly cats and dogs. A 26-year-old male presents with pruritic erythematous serpiginous linear skin lesion on the left lower leg for 2 weeks. The skin lesion was developed after walking in bare feet along the beach of an island in Philippines. Histopathologic finding showed a burrow containing numerous eosinophils and a few mononuclear cells in the epidermis. No parasite was found in multiple histologic section.
