The first rapid blood test for Ebola has been approved for use by the World Health Organization.
The test should allow patients to be identified, isolated and cared for as quickly as possible in an attempt to bring an end to the outbreak.
It is less accurate than conventional tests, but takes minutes rather than hours to get a result.
The ReEBOV Antigen Rapid Test developed by US company Corgenix, which searches the blood for a different part of the virus also works without electricity so it can be used in remote regions.
Trials in West Africa suggest it correctly identifies about 92% of people who have Ebola.
The current Ebola testing requires a laboratory to analyse the blood for fragments of the virus's genetic material which can take between 12 and 24 hours to get a definitive answer.
