Quick test on pinprick of blood could help stop Ebola in its tracks

Scientists have developed a quick, cheap, safe and field-deployable method to detect the Ebola virus in unprocessed whole blood.

The recent Ebola epidemic in West Africa was responsible for 11,310 deaths. Containing this deadly virus relies on rapid, reliable diagnoses, but Ebola is difficult to diagnose because it shares its initial symptoms with other diseases such as malaria and yellow fever. It usually takes weeks before patients develop the bleeding associated with Ebola haemorrhagic fever; by this time, they may have passed the infection on to others.

The standard method of detection is reverse transcription polymerase chain reaction (RT-qPCR), where chemical probes flag nucleic acids in the virus genome. This is reliable but involves deploying whole mobile laboratories and trained personnel. It is also expensive and results can take hours or even days, while the virus continues to spread. Another drawback is that it requires a blood draw, which is risky for both medical personnel and haemorrhagic patients.
