Report of the Twelfth WHOPES Working Group Meeting
More than 90% of nets tested at each time-point met the WHOPES criteria for the cone test, except for nets collected at 24 months post-distribution, when only 71% of nets met the WHOPES criteria for the cone test.
- 1.4 g/kg deltamethrin concentration for 100-denier net
- 1.8 g/kg deltamethrin concentration for 75-denier net
- 41.5% retention of deltamethrin concentration after 36 months
*more than half of nets tested had holes by 3-6 months of use
* 92.5% of nets had holes by 26 to 32 months
