The most cost-efficient strategy to maintain universal coverage is one that best optimizes the numbers of LLINs needed over time.
long-lasting insecticidal nets (LLINs)
The UCC in Muleba district of Tanzania was equitable, greatly improving LLIN ownership and, more moderately, usage.
The strong dependency of the effective lifetime on the pre-intervention transmission level indicated that the required distribution frequency may vary more with the local entomological situation than with LLIN quality or the characteristics of the distribution system.
The chlorfenapyr IRS component was largely responsible for controlling pyrethroid-resistant mosquitoes and the LLIN component was largely responsible for blood feeding inhibition and personal protection.
