Soil-transmitted helminth (STH) infections caused 4.98 million years live with disability globally in 2014, mostly affecting the poor. When farmers handle excreta for reuse in agriculture, involuntary ingestion of excreta particles is an important infection pathway for STH infections. The aim of ...

Estimation of involuntary excreta ingestion rates in farmers during agricultural practices in Vietnam
We studied the health risks related to wastewater and excreta reuse in an agricultural community in northern Vietnam, with a focus on intestinal parasitic infections and diarrhoeal diseases. Several epidemiological studies were conducted to assess the relative importance of exposure to wastew...

Objectives
We studied the influence of different additive materials (lime, and rice husk) and aeration conditions on Ascaris lumbricoides egg die-off in 24 vaults of an experimental excreta storage unit.
Methods
Excreta samples were collected once every two weeks over a 181-day period. Tempera...

Objectives
The aim of this paper was to assess the diarrhea risks caused by various pathogens among those exposed to biogas wastewater through different activities.
Methods
Application of quantitative microbial risk assessment (QMRA) of biogas wastewater was conducted in Hanam Province, Vietna...
The incidence of diarrhoea was monitored and the risk factors for diarrhoea were identified in the rural community of Hanam, Vietnam, over a period of one year. Compared to adults without direct contact to wastewater and excreta during their agricultural activities, those in direct contact had a ...

Diarrhoeal disease related to agricultural wastewater and excreta use in Vietnam
BACKGROUND: Despite the potential health risks of wastewater and excreta use as fertiliser in agriculture, it is still widespread in Vietnam. However, the importance of diarrheal risk in adults' associated with the combined exposures to both excreta and wastewater use in agriculture is largely un...

Diarrhoeal diseases among adult population in an agricultural community Hanam province, Vietnam, with high wastewater and excreta re-use
Poor wastewater management that results from a lack of appropriate sanitation infrastructure contributes to increasing health risks in urban areas in Côte d’Ivoire. We assessed the health risks associated with the use of wastewater for watering salad destined for human consumption, to help local ...

Human excreta are rich in plant nutrients, so many farmers in Vietnam use them to fertilize their crops and in raising fish. But they also contain dangerous pathogens: bacteria, viruses, protozoa, and the eggs of intestinal parasites. Exposure can pose a health risk to farmers, their families, as...
