Human Ascariasis: Diagnostics Update

As integrated control programmes develop, increased precision of diagnostic tests may improve the interpretation of the effect of complementing interventions, such as WASH [ ]. In addition, the number of eggs recorded in each smear is multiplied to calculate EPG, but the volume-to-weight ratio is affected by stool density, and actual weights vary considerably [ 23 ]. Moreover, improved coordination of disease mapping, including specimens sampled for other NTD surveys, could strengthen cooperation between health and non-health sectors, as well as attract sustainable funding for control programmes [].

Cross-reactivity of anti- Ascaris antibodies with epitopes of other helminths is common [ 51 ], and standardisation of Ascaris antigens for research and diagnostic purposes is warranted, including recombinant antigens, Ascaris -associated allergens and antigens of other ascarid species [ 565859 ].
