    Thanks to world-famous Colombian writer Garcia Marquez, many people think of Latin America as a land of magic. In his books, impossible things happen.

    Latin America includes more than 30 countries and areas located south of the United States in the American continent. From north to south, it starts from Mexico in North America, goes through the Caribbean and ends at the southernmost tip of South America.

    Latin America's environment is quite diverse. People can enjoy sunshine in the Caribbean islands, ride horses on the green grasslands of the Pampas, and explore volcanoes and snow-capped mountains in the Andes. {#blank#}2{#/blank#} Many of the world's most unique plants and animals live there.

    Imagine that you are in a remote village somewhere with no medical clinic.{#blank#}1{#/blank#}Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong.{#blank#}2{#/blank#}Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic (诊断的) tool.

    Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to correctly interpret what they see.{#blank#}3{#/blank#}With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.

    {#blank#}4{#/blank#}His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.

By inventing a medical tool that uses existing technology—mobile phones—Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere.{#blank#}5{#/blank#}
