At the center of Ebola in the Congo, worry and indifference coexist

One busy town affected by Ebola is at the crossroads of three nations.

MBANDAKA, Democratic Republic of Congo -- "Ebola, out! Ebola, out!" Those are the words children chant in unison after school in the Wangata district of Mbandaka, in the Democratic Republic of Congo.

Mbandaka is one of three areas affected by an Ebola outbreak in the central African nation and the focus of Ebola response efforts, since it's a hub in the region. Boats with passengers and goods travel to and from the city on a daily basis. Neighboring countries lie just across the busy Congo River.

Three people in Mbandaka have died from Ebola disease in the past few weeks and more than 400 people are being monitored because they are believed to be at risk.

The two other areas affected by Ebola, the towns of Bikoro and Iboko, have seen more cases -- 22 and 24 respectively -- but have fewer people passing through.

More than 11,000 people died during an Ebola outbreak in West Africa in 2014.

In this latest outbreak in the Congo, 51 cases of suspected Ebola have been reported so far, according to the country's health ministry. Of those, 35 are confirmed Ebola cases and 13 are considered probable. At least 25 people have died.

Hundreds of people who either know someone affected by Ebola, or know someone who knows someone else, have received shots so far -- including health workers.

While the vaccines could be a game-changer, experts caution that other measures are also important. Checks have been set up at airports and ports in key towns across the country.

In Mbandaka, the focus at the moment is actually convincing people to fight Ebola. Outreach teams are going house to house, talking with Church leaders and other community representatives, to raise awareness about the virus and the importance of precautionary measures.

What happens in the region matters because Mbandaka is located by Congo River -- the second longest river in Africa -- which is connected to the capital Kinshasa and to neighboring countries. While the outbreak is not considered to be an emergency of international concern at the moment, the risk of propagation is considered high at both a national and regional level. All nine neighboring countries have been placed under alert and advised to implement safety measures.

Many vendors at the market, who did not want to reveal their identities to ABC News, do not believe Ebola is real, or as a serious as they’re told.

In the capital Kinshasa, authorities say they are accustomed dealing with health emergencies and have expressed confidence in their ability to contain this latest outbreak.

"Every morning they have to wash their hands with theses chlorine dispensers and we take their temperature," Aime told ABC News. "We do the same before they go back home."

Monitoring the population is the current priority for health officials. Teams are going door to door to identify anyone who has been in contact with a person who has had either a confirmed or suspected case of Ebola.

The aim is to offer the vaccine all those who are potentially at risk.
