(M= number of months) Table 3a Evolution of the weekly risks, in one month, of getting an infective bite before and after full coverage in ITPS ZV alone with the difference of risks induced ITPS ZV Before After Diff. D1 1.9 0.3 -82.5% D7 12.8 2.4 -81.6% D14 23.9 4.7 -80.5% D21 33.7 7.0 -79.3% D28 42.2 9.1 -78.4% 3.3.2 Evolution of the monthly risk in one year Without vector control the risks were high with 44% in one month; 83% in three months; 97% in six months. After installation of ITPS ZV® the risks dropped respectively at 10%; 26%; and 46% (Table 3b). Insecticide treated plastic, model ZeroVector® alone, conferred a relatively more efficient and longer protection than LLINs alone, or in combination with ITPS ZF; with 50% till 7th month and even a 30% reduction of risk after one year (Graph 3c). Table 3b Evolution of the monthly risk of receiving an infective bite of main vector of malaria in a house before and after installation of ITPS ZeroVector® alone, and the difference of risks ITPS ZV Before After Diff.
