Officials in the Democratic Republic of Congo have confirmed the first case of Ebola in the major city of Goma, east of the country. Goma shares a border with Rwanda.
The current Ebola outbreak, the second worst in history, has contaminated nearly 2,500 people and killed more than 1,600.
The patient is a pastor who travelled to the city of Butembo, an Ebola hot spot, where he had laid hands on worshippers during prayers.
He started showing symptoms last week and was treated at home by a nurse.
On his arrival in Goma on Sunday, tests confirmed he had the Ebola virus.
Health officials in DR Congo say 18 people who travelled on the same bus as him have been identified.
They will be vaccinated as soon as possible.
Goma, which has a population of more than one million, has been preparing for this since the outbreak was declared a year ago.
Temperature screening points and hand washing stations are in place at the Rwandan border to control and prevent the spread of the disease.
This is the tenth outbreak to hit DR Congo and the deadliest so far.
The head of the World Health Organization has tweeted that Goma is prepared
