The World Health Organization (WHO) is worried that an Ebola patient who escaped from a health centre in the Democratic Republic of Congo last week is spreading the disease.
Community workers are searching for the man and encouraging people not to hide him.
Health workers wearing protective gear are standing by to take him back to the clinic in the eastern town of Beni.
The fugitive is one of six people who tested positive at a time when DR Congo was preparing to declare the Ebola epidemic over earlier this month.
More than 2,200 people have died since the outbreak began in 2018
