It's an entirely preventable disease, and when diagnosed early, it's easily treatable. Yet Malaria still claims hundreds of thousands of lives each year. All it takes is a single mosquito bite and you can become infected. In 2012, the tropical disease caused 627,000 deaths internationally, 90% of them in sub-Saharan Africa. The company Medical Diagnostic has developed a self-testing kit that can diagnose the disease in less than 30 minutes, and put sufferers on the path to recovery faster.
