An Ebola vaccination campaign will start in the Congolose city of Beni on Thursday after a new case of the virus was confirmed this week, the World Health Organization said on Wednesday.
More than 200 vaccine doses have arrived in that eastern DRC city.
A WHO spokesperson did not immediately respond to a request for comment.
The vast central African country has recorded 14 outbreaks since 1976. The 2018-2020 outbreak in the east was Congo's largest and the second largest ever recorded, with nearly 3,500 total cases.
The most recent outbreak was in Congo's northwest Equateur province and declared over in July after five deaths.
The latest confirmed case has been genetically linked to a 2018-2020 outbreak in North Kivu and Ituri provinces, which claimed nearly 2,300 lives.
Six people were killed in another flare-up from that same outbreak last year.
Congo's dense tropical forests are a natural reservoir for the Ebola virus, which causes fever, body aches, and diarrhoea, and can linger in the body of survivors only to resurface years later.
