Residual Infestation and Recolonization during Urban Triatoma infestans Bug Control Campaign, Peru1
|Treatment received||No. households||Initial prevalence, %
||Estimated residual infestation
|Observed||Estimated||Prevalence, %||No. (%) infested households|
|I and II||35,207||20.1||35.6||0.006||2 (0.3)|
|I only||7,521||7.0||12.2||0.16||14 (2.1)|
|II only||4,169||4.0||6.9||0.09||4 (0.5)|
*Estimates are calculated by using equations in Table 3 (estimated sensitivity of inspectors p = 57% [range 46%–66%] and probability of clearing households of infestation through 1 treatment c = 98.7% [range 98.4%–98.9%]). ND, no data.
†Extrapolation of the prevalence in households participating only in the second treatment to households that were never treated.
