We can now be pretty sure that the Ebola outbreak in the DR Congo is not an extension of the West African outbreak. The index case seems to have gotten the disease from a mammal she butchered, and the numerous other cases seem to stem from contact with her primary as health care workers and family members. I don’t think we have enough information yet to assess this outbreak vis-a-vis the genetics of the Ebola itself.
On 26 August 2014, the Ministry of Health, Democratic Republic of the Congo (DRC) notified the World Health Organization (WHO) of an outbreak of Ebola virus disease (EVD) in Equateur Province.
The index case was a pregnant woman from Ikanamongo Village who butchered a bush animal that had been killed and given to her by her husband. She became ill with symptoms of EVD and reported to a private clinic in Isaka Village. On 11 August 2014, she died of a then-unidentified haemorrhagic fever. Local customs and rituals associated with death meant that several health-care workers were exposed and presented with similar symptoms in the following week.
Between 28 July and 18 August 2014, a total of 24 suspected cases of haemorrhagic fever, including 13 deaths, have been identified. Human-to-human transmission has been established and includes the health-care personnel who were exposed to the deceased pregnant woman during surgery (one doctor and two nurses) in addition to the hygienist and a ward boy, all of whom developed symptoms and died. Other deaths have been recorded among the relatives who attended the index case, individuals who were in contact with the clinic staff, and those who handled the bodies of the deceased during funerals. The other 11 cases are currently being treated in isolation centres.
