Kulinda is designed to prevent transmission of HIV through breastfeeding in sub-Saharan Africa. It is a simple, clear, binary indicator which works in conjunction with a process called Flash Heating to show when HIV has been deactivated in breast milk. This enables HIV positive mothers with limited resources in sub-Saharan Africa to accurately treat their breast milk before feeding to their babies, providing them with food and nutrients in a safe, economical way. Each device costs 20p and can be provided with a pictorial instruction booklet, bag and container.
