Table 6. Number of studies (n = 94) that investigated STH species and WASH domains.
Studies | Water | Sanitation | Hygiene | Water and Sanitation | Water and Hygiene | Sanitation and Hygiene | Water, Sanitation, and Hygiene |
Any STH (grouped) | 34 | 44 | 28 | 32 | 16 | 21 | 15 |
A. lumbricoides | 43 | 59 | 37 | 38 | 20 | 30 | 18 |
Hookworm | 34 | 53 | 37 | 28 | 17 | 30 | 14 |
T. trichiura | 38 | 52 | 34 | 34 | 20 | 28 | 18 |
S. stercoralis | 10 | 11 | 6 | 9 | 4 | 5 | 3 |
Total (all studies) | 56 | 79 | 53 | 49 | 26 | 42 | 23 |
Each cell indicates the number of reviewed studies that investigated both an STH species (or any STH) and WASH domains. Higher numbers suggest that certain WASH-STH relationships are more commonly explored in the literature.
