REPUBLIC OF CONGO · EXPLAINER
Key Facts
- The country Two countries share the Congo River: the Republic of Congo (Brazzaville) and DR Congo (Kinshasa).
- What happened From 3 November, US-bound flyers must attest they were not in DR Congo for 21 days.
- The size DR Congo, the Democratic Republic of the Congo, has about 112.8 million people; its neighbour has 6.5 million.
- The money The Republic of Congo’s economy is about US$16.3 billion; DR Congo’s is about US$91.0 billion.
- The Ebola count The US health agency CDC counts 10,305 confirmed cases as of 28 October; 10,274 are in DR Congo.
- Prediction markets Polymarket gives 23.0% that the Republic of Congo records an Ebola case in 2026 (2 November, 2:40 a.m. ET).
The two Congos are not a spelling choice, because these are two separate countries on opposite banks of the Congo River. On Monday 2 November 2026 the difference decides which health and travel rules apply to you.
The Republic of Congo has about 6.5 million people and its capital in Brazzaville. DR Congo has about 112.8 million and its capital in Kinshasa, and our travel rules guide covers entry steps for Americans.
In Plain English, Who Is Who
The World Bank, the Washington-based development lender, publishes the population and economy figures used here, all for 2025 unless stated. The CDC, the US Centers for Disease Control and Prevention, is America’s national public health agency, and it issues the Ebola counts and travel notices.
Ebola is a deadly virus spread by contact with the body fluids of sick people. A confirmed case is one proven by a laboratory test.
The CFA franc is the shared money of six Central African states, including the Republic of Congo. It is tied to the euro at a fixed rate.
The Two Congos at a Glance
Among the two Congos, the first had 6,484,437 people in 2025, the World Bank says. The second had 112,832,473, about 17 times as many.
It is also about seven times larger, at 2,345,410 square kilometres (about 905,600 square miles) in 2024. The Republic of Congo covers 342,000 square kilometres (about 132,000 square miles).
The Republic of Congo’s economy was about US$16.3 billion in 2025, or US$2,515 per person. DR Congo’s was about US$91.0 billion, but shared among so many people it comes to only US$807 each.
The State Department says the Republic of Congo’s economy relies mainly on petroleum, which helps explain its higher income per head. Our guide to the oil economy shows how much the budget depends on crude.
Two Capitals Face to Face
The two Congos meet face to face at their capitals. Brazzaville and Kinshasa stand on opposite banks of the Congo River, so crossing the water means crossing a border.
Africa50, an African infrastructure investment company, says both governments chose it as lead developer of a 1.575-kilometre (about 1-mile) toll bridge. The bridge would carry two road lanes and one railway track.
Africa50 expects more than 5 million passengers a year. Its page describes the project as still in the preparation and development phase.
Two Histories and Two Names
Both countries gained independence in 1960, the State Department says, the Republic of Congo from France and DR Congo from Belgium. DR Congo was formerly called Zaire.
In 1997 Laurent Kabila overthrew Mobutu Sese Seko, whose regime had lasted 32 years, the State Department says. A civil war also broke out in the Republic of Congo in mid-1997.
Denis Sassou Nguesso has led the Republic of Congo for nearly all the years since 1979, with a five-year gap, the State Department says. His long tenure is a different political story from the one across the river.
Money and Minerals Differ
On Monday 2 November 2026, the Republic of Congo uses about 587 CFA francs (US$1), and DR Congo about 2,309 Congolese francs (US$1). The two currencies are separate, so carry the right one for each bank of the river.
The State Department puts DR Congo’s mineral reserves at an estimated US$25 trillion and says it borders nine countries. For prices and cash habits on the ground, see our cash guide for visitors.
Ebola and the 3 November US Flight Rule
The CDC says 10,305 confirmed Ebola cases and 4,996 confirmed deaths had been counted as of 28 October, in an update dated Friday 30 October. DR Congo accounts for 10,274 cases and 4,992 deaths.
The CDC also lists cases in Kenya, Nigeria, Uganda and France, but none in the Republic of Congo. Our Ebola report has the wider picture.
The CDC issued an amended order on 28 October, and the Federal Register, the government’s daily rulebook, published it on 30 October. It bars airlines from boarding US-bound passengers unless they sign a statement saying they were not in DR Congo in the past 21 days.
The order takes effect at 11:59 p.m. Eastern on Tuesday 3 November, for flights departing at or after that time. It runs through Friday 18 December unless the CDC changes it.
It names only DR Congo, so a traveller who stayed in the Republic of Congo can sign truthfully. For the two Congos, that is the rule that matters most to Americans this month.
What Prediction Markets Say
Polymarket, a prediction market where users bet real money, gave 23.0% to an Ebola case in the Republic of Congo in 2026. That was at 2:40 a.m. ET on 2 November, and the contract had drawn US$16,956 in bets.
The wider question on which countries will have a case had drawn US$77,603. A bet is not a forecast by health officials, and the CDC list shows no case in the Republic of Congo so far.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
What It Means for US Readers
With the two Congos, check the country on your ticket first, because a booking to Brazzaville and one to Kinshasa fall under different rules. A side trip across the river within 21 days of a US-bound flight would make the attestation untrue.
Keep the dates of every border crossing. The split between the two Congos also matters for investors, since an oil exporter and a mining giant move different markets.
For the political picture on the other bank, read our guide to DR Congo politics. Our report on the Republic of Congo’s place in Africa covers its role in regional clubs.
What Is Not Known
It is not known whether the CDC will add the Republic of Congo to its Ebola notices. Nor is it known whether the attestation order will be widened before it expires on 18 December.
The Africa50 page gives no construction start date for the bridge between the two capitals. The CDC counts are as of 28 October and will have moved since, so the picture for the two Congos can change.
