Fletcher Lab’s mobile phone-based microscope receives Gates Foundation support
The Bill & Melinda Gates Foundation awarded a grant to Berkeley in July 2019 to support the scaled-up production of the LoaScope, a mobile phone-based microscope developed by Blum Center Chief Technologist Daniel Fletcher and researchers in his bioengineering laboratory, to enable mapping of Loa loa prevalence and intensity in Central and West Africa. The LoaScope uses video from the mobile phone-based microscope to automatically detect and quantify infection by parasitic worms in a drop of blood.
Loa loa, commonly referred to as African eye worm, is passed on to humans through the repeated bites of deer flies in West and Central Africa rainforests. Knowing whether someone has a Loa loa infection and the intensity of that infection is critical for mass drug administration efforts to eliminate onchocerciasis (river blindness) and lymphatic filariasis (elephantiasis). There may be more than 29 million people who are at risk of getting loaisis in affected areas of Central and West Africa, according to the Centers for Disease Control and Prevention.
