  abstract = {{E}xperimental huts are part of the {WHO} process for testing and evaluation of {I}nsecticide {T}reated {N}ets ({ITN}) in semi-field conditions. {E}xperimental {H}ut {T}rials ({EHT}s) mostly focus on two main indicators (i.e., mortality and blood feeding reduction) that serve as efficacy criteria to obtain {WHO} interim recommendation. {H}owever, several other outputs that rely on counts of vectors collected in the huts are neglected although they can give useful information about vectors' behavior and personal protection provided by {ITN}s. {I}n particular, {EHT}s allow to measure the deterrent effect and personal protection of {ITN}s. {T}o provide a better assessment of {ITN}s efficacy, we performed a retrospective analysis of the deterrence and the personal protection against malaria transmission for 12 unwashed and 13 washed {ITN}s evaluated through {EHT}s conducted in {W}est {A}frica. {A} significant deterrent effect was shown for six of the 12 unwashed {ITN}s tested. {W}hen washed 20 times, only three {ITN}s had significant deterrent effect ({R}ate {R}atios ({RR})<1; p<0.05) and three showed an apparent "attractiveness" ({RR}> 1; p<0.01). {W}hen compared to the untreated net, all unwashed {ITN}s showed lower number of blood-fed {A}nopheles indicating a significant personal protection ({RR}<1, p<0.05). {H}owever, when washed 20 times, three {ITN}s that were found to be attractive did not significantly reduce human-vector contact (p>0.05). {C}urrent {WHO} efficacy criteria do not sufficiently take into account the deterrence effect of {ITN}s. {M}oreover, the deterrence variability is rarely discussed in {EHT}'s reports. {O}ur findings highlighted the long-range effect (deterrent or attractive) of {ITN}s that may have significant consequences for personal/ community protection against malaria transmission. {I}ndicators measuring the deterrence should be further considered for the evaluation of {ITN}s.},
