Tanzania -- Rukia Ibrahim and Ferhla Yahaya remove poor-quality threads from giant bobbins at the A-Z Textiles Mills LTD, located in Arusha, Tanzania. This special yarn is embedded with insecticide and used for weaving long-lasting mosquito netting that can protect someone from malaria without re-treatment for over five years. This unique program supported by A-Z uses traditional bed netting as window and doorway screen protection in homes where the residents cannot afford modern window and door screens.
