KINSHASA (Reuters) - The Democratic Republic of Congo and U.N. agencies said on Sunday they began deploying emergency teams of specialists over the weekend to try to prevent the spread of an Ebola epidemic suspected to have infected more than 30 people.
The World Health Organisation (WHO) obtained 4,000 doses of an experimental Ebola vaccine and was preparing for deployment into Congo, the WHO's regional director for Africa, Matshidiso Moeti, told Reuters by telephone on Sunday.
Only two cases have so far been confirmed in a laboratory.

The latest suspected case was reported on Friday in the northwestern province of Equateur, which Health Minister Oly Ilunga Kalenga visited on Saturday with officials from the WHO and the United Nations Children's Fund (UNICEF).
President Joseph Kabila also met WHO Director-General Tedros Adhanom Ghebreyesus in Kinshasa on Sunday.
Moeti said some 362 contacts had been traced of those who had fallen sick - a necessary precursor of deploying the vaccines. She added that two of those contacts had got to the provincial capital Mbandaka. The biggest worry since the epidemic was identified has been that it could spread there.
"We're concerned because this is a city of one million people," she said.
Congo first reported the outbreak, centered around the village of Ikoko Impenge, near the town of Bikoro, on Tuesday, with 32 suspected, probable or confirmed cases of the disease, including 18 deaths since April 4. Some deaths occurring as early as January have not yet been linked to the epidemic.
"It is evident that two or three months earlier, some cases of hemorrhagic fever and some deaths occurred," Moeti said. "Work is underway to determine the beginning of this epidemic."
Officials are racing to prevent the virus from spreading out of control, as happened in West Africa from 2014-2016, when Ebola killed more than 11,300 people in Guinea, Sierra Leone and Liberia.
The WHO was criticized for bungling its response to that epidemic.
Congo had suffered eight previous Ebola epidemics, but owing to remote geography and poor transport links they have tended to fizzle out rather than spread to become a national crisis.
But this epidemic's proximity to the Congo River, a major transport route and lifeline both to Congo's capital Kinshasa and to neighboring Congo Republic's capital Brazzaville, makes it more likely the virus could break out into a wider area.
The disease - most feared for the internal and external bleeding it can cause in its victims due to damage done to blood vessels - has already spread to three separate locations covering 60 km (37 miles) or more in Equateur province.
Congo's nine neighbors have been put on high alert in case Ebola crosses a border, especially to Republic of Congo or Central African Republic.
"The WHO is strengthening its presence, positioning a dozen epidemiologists who will be divided on the axes of Mbandaka, Bikoro and Iboko to investigate alerts," its Congo representative Allarangar Yokouide said.
The WHO said on Friday it hopes to deploy an experimental Ebola vaccine to tackle an outbreak.
