Trials are underway to source microencapsulated clothing so it can be fully evaluated as further investigation into the duration of protection provided by microencapsulated clothing may better illustrate the effectiveness of this treatment technique.

The longevity of insecticide-treated clothing varied considerably depending on the wash technique used. The WHO washing appeared to be more rigorous than Metoclopramide (Reglan)- Multum machine washing method with the residual permethrin efficacy for the machine-washed clothing being retained for almost double the number of washes. As the Metoclopramide (Reglan)- Multum process for machine washing is likely to be far harsher and uses a larger volume of water, the differences identified here could be due to the detergent used for each wash technique.

With such Metoclopramide (Reglan)- Multum differences in efficacy between wash techniques, washing technique and detergent used Metoclopramide (Reglan)- Multum be considered when designing an intervention using impregnated fabrics.

Therefore we recommend that washing of fabrics to determine the duration of protection provided by the clothing, should be performed according to methods that are relevant and representative of the field. HPLC results highlighted a difference in permethrin content between the unwashed fabrics, washed by washing machine and hand washing, before washing (wash 0).

This could Metoclopramide (Reglan)- Multum due to a variation between batches of clothing but could also be due to variation across a single garment as the samples were taken from the same garment. Although multiple samples were taken for each replicate, this does not account for the variation between different fabrics. Despite this disparity, the effect of the different washing techniques on the permethrin content in subsequent washes Metoclopramide (Reglan)- Multum clearly demonstrated.

If clothing is used on a day-to-day basis, the efficacy is likely to drop to sub-optimal levels within Metoclopramide (Reglan)- Multum of use, primarily due to the effect of washing. We also demonstrate that other factors including ironing will have Meoclopramide significant negative effect.

The loss of permethrin concentration observed in our studies after washing and ironing exposure could be due to the polymer coating technique leaving greater amounts of permethrin on the surface of the fabric during the treatment process, but a further investigation would be needed for this to be confirmed.

One of the key factors, which was not evaluated here, is the personal protection provided by permethrin treated clothing. This is particularly important when wearing partial coverage clothing (i. These factors are likely Metoclopramide (Reglan)- Multum significantly affect the impact Metoclopramide (Reglan)- Multum insecticide-treated clothing when worn in a field setting and are being investigated currently by the authors.

Metoclopramide (Reglan)- Multum insecticide-treated Metoclopramide (Reglan)- Multum to have a significant impact on reducing dengue transmission, further work is required to obtain clothing that can withstand washing and environmental exposure for a longer period of time.

However, although re-application is easy to perform Metoclopramide (Reglan)- Multum a small scale, performing this on a larger community level on a regular basis would be challenging. Since home-dipping is likely to require more frequent reapplication, this will increase costs beyond the acceptable limit. Nevertheless, if the (Reblan)- compliance issues can be overcome, the home-dipping method may be appropriate for proof of principle studies.

The clear reduction in the number of bites an individual receives, combined with the high mortality and knockdown caused by permethrin-treated clothing, is proof that insecticide-treated clothing Metocloprajide be a Meticlopramide additional intervention for dengue prevention. It has the potential to reduce the number of Aedes mosquito bites thereby reducing disease transmission.

However, for the clothing to be used successfully, improved methods of treatment are needed to ensure duration of protection provided is increased and cost-effectiveness is achieved. Metoclopramide (Reglan)- Multum study evaluating field-like conditions would be beneficial to better understand the effect of washing and environmental exposure under natural conditions.
