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, ⁠higher than the 85% global benchmark it said was needed to break the chain of transmission.

Kenya's cases are linked to the Ebola epidemic in Congo — the second-largest outbreak ever recorded, with more than 9,000 cases and more than 4,000 deaths. [...]
