Ebola

We are currently responding in the Democratic Republic of Congo to the second-worst Ebola outbreak in history

Ebola is one of the world’s most deadly diseases.

It is a highly infectious virus that can kill up to 90 percent of the people who catch it, causing terror among infected communities.

Ebola is so infectious that patients need to be treated in isolation by staff wearing protective clothing.

Congo Ebola outbreaks, 2018-19

Current outbreak: northeast congo

On 1 August 2018, we began responding to a new Ebola outbreak in North Kivu province in the northeast of the Democratic Republic of Congo – a region recently characterised by violence and instability. 

Since then, it has spread to neighbouring Ituri province.

With a total of 1,044 cases and 652 deaths, as of 27 March 2019, the current outbreak is now the second worst Ebola outbreak in history - following the 2014 West Africa epidemic.

The epicentre of the epidemic has moved multiple times. Beginning in the town of Mangina, the outbreak spread to the larger city of Beni. 

Today, cases are confirmed in hotspots around Butembo, in rural areas like Katwa, Kalenguta and Kyondo.

Stopping the spread

A serious concern is that some new cases are not linked to any previously known chains of transmission. This makes it more difficult to trace contacts and control the evolution of the outbreak. In Katwa, 43 percent of patients have no known links to previous patients.

North Kivu's proximity to neighbouring Uganda also presents a risk of international spread, with regular trade and traffic across the border.

However, since the beginning of the outbreak, the Congolese Ministry of Health has followed up with thousands of people who have been in contact with Ebola patients. 

Alongside this response, 92,868 people have been vaccinated, including 5,154 health workers by MSF.

Attacks on Ebola treatment centres

The response in North Kivu is the first time that MSF has faced an Ebola outbreak in an area of conflict, making our ability to limit the spread of the disease more challenging.

As of 27 March, MSF has been forced to suspend medical activities at Ebola Treatment Centres (ETCs) in Katwa, Butembo, Biena and Biakato following successive violent attacks on the facilities. This follows an escalation of tensions around the international Ebola response.

The Equateur outbreak

Between May and July 2018, MSF teams ran a three-month-long emergency intervention in Equateur Province of the Democratic Republic of Congo (DRC) to respond to the Ebola outbreak.

Congolese Ministry of Health teams supported by MSF in Bikoro, Itipo, Mbandaka and Iboko, provided care to 38 confirmed patients, 24 of whom survived and returned to their homes. Sadly 14 people died.

A total of 3,199 people were vaccinated against Ebola with the investigational Ebola vaccine rVSVDG-ZEBOV-GP under WHO’s Expanded Access Framework by teams from MSF, WHO and the Congolese Ministry of Health.

MSF teams alone vaccinated some 1,673 people in the Bikoro and Itipo areas, including the contacts of confirmed Ebola patients and their contacts, and frontline workers considered to be most at risk of contracting the virus.

MSF ended the response on 2 July 2018, and the outbreak was officially declared over on 24 July.

West Africa Ebola outbreak, 2014-16

The Ebola outbreak in West Africa killed 11,315 people after being officially declared on 22 March 2014 in Guinea.

During the Ebola emergency, 28 of our staff members caught Ebola. Fourteen recovered but 14 died.

The vast majority of these infections were found to have occurred in the community.

On 22 December 2016, the results of an experimental Ebola vaccine trial were released by the Lancet. The trial found the vaccine to be highly effective in protecting people against the Zaire strain of Ebola.

“This vaccine will be a powerful tool to help prevent the spread of the Zaire strain of Ebola and to protect health workers," said MSF President Dr Bertrand Draguez. 

"MSF will try to make use of it in any future outbreak of the disease. More research is still needed to determine the length of protection that it offers to people and into vaccines for other strains of Ebola. Progress also still needs to be made in improving the treatment of patients once they are infected with Ebola, to make sure more lives can be saved.”

Prior to the 2014 outbreak, it is estimated there had been over 1,800 cases of Ebola, with nearly 1,300 deaths.

Ebola history

The Ebola virus was first associated with an outbreak of 318 cases of a haemorrhagic disease in Zaire (now the Democratic Republic of Congo [DRC]) in 1976. Of the 318 cases, 280 died — and died quickly.

That same year, 284 people in Sudan also became infected with the virus, killing 156.

There are five different strains of the Ebola virus: Bundibugyo, Ivory Coast, Reston, Sudan and Zaire, named after their places of origin.

Four of these five have caused disease in humans. While the Reston virus can infect humans, no illnesses or deaths have been reported.

Before the 2014 outbreak, MSF had treated hundreds of people affected by Ebola in UgandaRepublic of Congo, DRC, Sudan, Gabon and Guinea

In 2007, MSF entirely contained an epidemic of Ebola in Uganda by placing a control area around the treatment centre.

What causes Ebola?

Ebola can be caught from both humans and animals. It is transmitted through close contact with blood, secretions, or other bodily fluids.

Healthcare workers have frequently been infected while treating Ebola patients. This has occurred through close contact without the use of gloves, masks or protective goggles.

In areas of Africa, infection has been documented through the handling of infected chimpanzees, gorillas, fruit bats, monkeys, forest antelope and porcupines found dead or ill in the rainforest.

Burials where mourners have direct contact with the deceased can also transmit the virus, whereas transmission through infected semen can occur up to seven weeks after clinical recovery.

Symptoms of Ebola

Early on, symptoms are non-specific, making it difficult to diagnose.

The disease is often characterised by the sudden onset of fever, feeling weak, muscle pain, headaches and a sore throat. This is followed by vomiting, diarrhoea, rashes, impaired kidney and liver function and, in some cases, internal and external bleeding.

Symptoms can appear from two to 21 days after exposure. Some patients may go on to experience rashes, red eyes, hiccups, chest pains, difficulty breathing and swallowing.

Diagnosing Ebola

Diagnosing Ebola is difficult because the early symptoms, such as red eyes and rashes, are common.

Ebola infections can only be diagnosed definitively in the laboratory by five different tests.

Such tests are an extreme biohazard risk and should be conducted under maximum biological containment conditions. A number of human-to-human transmissions have occurred due to a lack of protective clothing. 

“Health workers are particularly susceptible to catching it so, along with treating patients, one of our main priorities is training health staff to reduce the risk of them catching the disease whilst caring for patients,” said Henry Gray, MSF’s emergency coordinator, during an Ebola outbreak in Uganda in 2012. Henry also worked on the 2014 outbreak. 

“We have to put in place extremely rigorous safety procedures to ensure that no health workers are exposed to the virus – through contaminated material from patients or medical waste infected with Ebola.”

Treating Ebola

No specific treatment or vaccine is yet available for Ebola.

Standard treatment for Ebola is limited to supportive therapy. This consists of hydrating the patient, maintaining their oxygen status and blood pressure and treating them for any complicating infections.

Despite the difficulty of diagnosing Ebola in its early stages, those who display its symptoms should be isolated and public health professionals notified.

Supportive therapy can continue with proper protective clothing until samples from the patient are tested to confirm infection. Once a patient recovers from Ebola, they are immune to the strain of the virus they contracted.

An Ebola outbreak is officially considered at an end once 42 days have elapsed without any new confirmed cases.
