Table 1. Gastrointestinal parasite (GIP) infections identified in 2,263 Nepalese Gurkha recruits who had recently migrated to the UK between 2012 and 2020, showing number of infections, percentage prevalence, and percentage of total infections by organism.

It was not possible to differentiate between members of the E. histolytica complex using light microscopy.

Organism	No. of infections	% Prevalence	% of total infections
Giardia duodenalis	231	10.2%	44.0%
Strongyloides stercoralis: All tests	102	4.5%	19.4%
IgG ELISA positive*	99	4.4%	18.9%
Culture positives	4	<1%	<1%
Hookworm species	86	3.8%	16.4%
Entamoeba histolytica complex	46	2.0%	8.8%
Trichuris trichiura	27	1.2%	5.1%
Hymenolepis nana	20	0.9%	3.8%
Ascaris lumbricoides	6	<1%	1.1%
Trichostrongylus sp.	5	<1%	<1%
Enterobius vermicularis	1	<1%	<1%
Unidentified trematode ovum**	1	<1%	<1%
Total	525

*Two different Strongyloides IgG ELISAs were used over the study period. See Methods for more details.

**Whilst not definitively identified, the ovum was noted to be large, oval in shape, and operculated; therefore most likely fasciolid.
