Problem being addressed[edit | edit source]
Tuberculosis is the second largest infectious cause of death in the world. It is highly prevalent in low resource settings because the equipment necessary, fluorescence microscopes, is high cost ($40,000 USD), leading to difficulty in properly diagnosing the infection.
Detailed description of the solution[edit | edit source]
The Global Focus Microscope analyses sputum smears (saliva and mucus mixture coughed up by a patient) to detect the presence of tuberculosis and malaria. The device is portable (small size and weight), is battery operated, has up to 1000x magnification, and is a low cost option ($240 USD to manufacture).
