PathVis: A Water Monitoring Device for Vibrio cholerae Detection
by OmniVis

In 2017 the number of cholera cases worldwide catapulted when over 1 million individuals were infected in war-torn Yemen. Prevention strategies are a lower priority in conflict areas, due to the time and effort needed with cholera detection methods, balanced against more immediate priorities. However, early detection of the cholera pathogen, Vibrio cholerae, in water with a portable device capable of rapid assessment would enable proactive remediation strategies.

OmniVis has designed a smartphone platform diagnostic device that uses DNA amplification to detect for V. cholerae, at the source, in under 30 minutes. The data is immediately uploaded to a cloud-based server to automate the data logging process. In areas without connectivity, wifi can be used in a central location for data upload. OmniVis is the first and only water-based V. cholerae detection device that automates data logging with time-stamped, geographical location information.
