Operation Outbreak (OO) is an iPhone app developed by THE BROAD INSTITUTE INC. It falls under the category of Education & Reference and is available for free. This app allows users to participate in a simulated outbreak scenario where they can learn about the spread of diseases and preventive measures.

The main feature of Operation Outbreak is its use of Bluetooth technology to simulate the spread of a "virtual pathogen" through phones. Users can experience a realistic outbreak scenario and understand the importance of adopting preventive measures such as social distancing and mask wearing. The app also includes quizzes about biology and public health, providing users with an interactive learning experience.

To participate in the outbreak simulation, users need a code from a simulation organizer. This ensures that the app is used in educational settings and maintains a controlled environment for learning. Operation Outbreak offers a unique and engaging way to understand the dynamics of disease spread and the impact of preventive measures.
