  • Title: Breteau Index threshold levels indicating risk for dengue transmission in areas with low Aedes infestation.
    Author: Sanchez L, Cortinas J, Pelaez O, Gutierrez H, Concepción D, Van der Stuyft P.
    Journal: Trop Med Int Health; 2010 Feb; 15(2):173-5. PubMed ID: 20409286.
    Abstract:
    We used Breteau Indices to - retrospectively - predict dengue transmission. The presence of one house block (on average about 50 houses) with a Breteau Index >or=4 in a neighbourhood (a block plus the surrounding blocks in a radius of 100 m) predicted transmission at the latter level with 81.8% sensitivity and 73.3% specificity during the first month of the Havana 2001 dengue outbreak. This result corroborates the external validity of this threshold, at least in situations with low infestations levels.
