Transmission of helminth eggs through hands in a high-risk community


Background The role that hands play in the transmission of Ascaris is not well understood.

Methods A newly developed method to quantify the presence helminth eggs on hands was tested among a group of farmers in Vietnam. High turbidity in hand rinse samples meant that the adopted sugar solution had to be replaced by zinc sulphate as a flotation solution.

Results The survey found 34% (31/90) of study participant hands' were positive for helminth eggs, though concentrations were low and ranged from 0–10 eggs/2 hands. The use of fresh excreta in agriculture was the only variable that showed an association with the concentrations of eggs found on hands.

Conclusions The results highlight the need to promote handwashing with soap to prevent the transmission of soil-transmitted helminth infections.
