UPDATE 1 — Kenya confirms four new Ebola cases, bringing total number to seven

(Recasts, adds details throughout) Oct 17 (Reuters) — Kenya confirmed four new cases of the Ebola Bundibugyo virus on Saturday, including three health workers who treated the country's first patient, bringing the total number of confirmed cases to seven, the health ministry said. The other new case is a male relative of the index patient, who died. The relative had been in quarantine since October 6, the ministry said in a statement. The cases are the first known infections passed on inside Kenya, where the first patient arrived from Congo on October 3. But the ministry says it has traced and quarantined nearly all of his contacts and there is no evidence that the virus is spreading in the community. The three health workers — two men and a woman aged 29, 35 and 32 respectively — managed the index case on October 3 and 4 and had been in quarantine since October 9, it said. All four new patients were already in quarantine when they developed symptoms and were diagnosed. The second and third patients confirmed earlier are stable and responding well to supportive treatment, the ministry said. It said 128 of 130 listed contacts, or 98.5%, had been traced and placed in quarantine, highe
