A new method for rapid diagnosis of Ebola has been tested in a field trial in Guinea. The test procedure was carried out using a portable suitcase laboratory. The mobile suitcase lab is operated with solar power and enables simple on-site diagnostics in remote areas without the need of an equipped laboratory. The new detection method is based on the rapid identification of viral RNA in oral swabs of infected persons at 42 degrees. An Ebola infection case was detected after 30 minutes.
