A revolutionary device developed by a team of Cambridge scientists is transforming the diagnosis of HIV in sub-Saharan Africa. More than 20 million people in sub-Saharan Africa are thought to be carrying HIV, the virus that causes Aids. “So many devices for dealing with conditions like HIV are created in the developed world,” said Lee. Until now, people have had to travel to health centres to provide a blood sample and then return weeks later for the results of their test. Samba works by drawing a blood sample from a patient and then feeding it into a disposable cartridge that contains chemicals including a particular genetic sequence found only in HIV.
