MOSQUITO NET alphacyp+chlorfen. (Interceptor G2) 2 persons

• Mosquito net containing pyrethroid insecticide, alphacypermethrin and a new class of chemical the chlorfenapyr. Chlorfenapyr is a pyrrole insecticide that disrupts mitochondrial function, targeting the energy production in mosquitoes, leading to their death. This mode of action is different from all other adulticides used in vector control, which are neurotoxic. Therefore, chlorfenapyr is active against insecticide resistant and susceptible mosquitoes. It confers no cross-resistance to neurotoxic insecticides and there is no reported resistance in Anophelines to date.
• Long-lasting insecticidal nets (LLIN) are manufactured with an insecticide coated onto the LLIN materials. These LLINs are ready-to-use with insecticide components lasting 20 washes/3 years of use in standard laboratory conditions.

Use of LLINs:

• LLINs can be used indoors or outdoors and provide a physical and chemical barrier conferring personal protection to persons sleeping under it from exposure to infectious malaria vectors.
• In addition to a physical barrier against flies, spiders cockroaches and snakes, LLINs may exert a killing effect against lice, fleas, sand flies, and bedbugs.
• To exclude mosquitoes, insects and snakes the bottom of the LLIN must be tucked under the mattress/sleeping mat or allowed to hang so it touches the ground all around.
• At certain thresholds of LLIN coverage and use, a “mass killing effect” against the local anopheline population may develop where the survivorship, sporozoite rate and human biting density are reduced and subsequently mortality and morbidity decrease. At high coverage and utilization thresholds the “mass killing effect” extends the protective effect to non-protected community members within a community.
• The effectiveness of LLINs is contingent upon the population having access to LLINs and the willingness and ability of persons to use them correctly and consistently for as long as possible.
• Record the number of washes on the label of the net.
• Mosquito nets are made available to MSF staff, but it is the responsibility of each individual to make sure they have one, use it correctly and properly care and repair it when needed.

Distribution and coverage:

• When planning a mass distribution of LLINs it is important to consider:
• estimation of number of LLINs required = total population / 1.8
• distribution at household level should strive to achieve universal access (i.e. 100% of households reporting 1 LLIN used per 2 persons sleeping in the household)
• To maximise the likelihood of universal access and avoid under or over distributing LLINs the following may be useful
• 1-2 persons: 1 LLIN to be distributed
• 3-4 persons: 2 LLINs to be distributed
• 5-6 persons: 3 LLINs to be distributed
• 7-8 persons: 4 LLINs to be distributed
• Distribution of LLINs should be accompanied by appropriate health promotion and community engagement to overcome barriers to effective usage and promote LLIN importance:
• correct and consistent LLIN utilization
• proper LLIN maintenance and care
• A survey to evaluate LLIN coverage and use is recommended.
• for survey to evaluate LLIN durability contact EHA referent for further details

Care and repair:

• LinsectiLIN repair at the household level is essential to close holes and tears in LLINs quickly before hole or tear size increases. Net repair can be carried out in multiple ways, including sewing, tying a knot, string or elastic band, or patching.
• Avoid vigorous and frequent washing as it will remove insecticide. Wash LLINs with cold water and mild detergent only, never disinfect with chlorine solutions or chlorine containing products. Chlorine potable water (containing up to 1mg/l of free residual chlorine) can be used for washing without causing damage to LLINs. Throw the washing water into latrine, never dispose it in living waters.
• After washing, the LLIN should be dried in the shade. Avoid prolonged exposure to direct sunlight because UV radiation will destroy t.insecticide.
