The real-time knowledge on camp locations and populations would facilitate health interventions such as vaccination delivery or sensitisation and information campaigns.

Table 6 Subdivisions of the skin sensitisation data set into binary classes.
We used information from the clinical investigative subsample, in which 91% of the children were tested either by SPT or blood sample, regardless of the presence of symptoms, to conduct multiple imputations on missing sensitisation data.
In addition, we used information on sensitisation from a random subsample of children evaluated clinically at 2 years of age.
