Kenya’s Ebola outbreak has grown to seven confirmed cases after four new infections were reported on Saturday.

Three of the new patients are health workers who treated the country’s first patient.

They are the first known Ebola infections passed on inside Kenya; earlier cases were imported.

The first patient fell ill in Congo, travelled through Uganda, flew to Nairobi on October 3 and died on October 5.

All four new patients were already in quarantine when symptoms began, and there is no sign of community spread.

Officials have traced and quarantined 128 of 130 contacts, or 98.5%, above an 85% global benchmark.

There are no approved vaccines or treatments for the Bundibugyo strain, so care is supportive only.

The cases are linked to Congo’s epidemic, the second-largest ever, with more than 9,000 cases.

Contacts will be watched through a 21-day observation period, and more cases could still emerge.
