RUNNING BEHIND THE OUTBREAK

In the Democratic Republic of Congo, healthcare teams are facing an uphill struggle to beat the ongoing Ebola epidemic

Almost 700 people have now died as the Ebola outbreak in the Democratic Republic of Congo (DRC) enters its ninth month.

In the past few weeks, the number of new cases has soared, while the international response has struggled to adapt to people’s needs and overcome growing mistrust.

“In this epidemic, rather than just one big epicentre, we see multiple small clusters all over the place – and we’re finding it difficult to track them and predict where the next one is going to happen,” admits doctor Natalie Roberts, emergency manager for MSF.

“It feels like we’re running behind the outbreak, like we’re not in control.”

She recently came back from North Kivu, in eastern DRC, where over 1,100 people have fallen sick with Ebola and over 60 percent of them have died since the epidemic broke out in August last year.

Her words express a well-known issue for organisations working under the lead of the DRC's Ministry of Health:

While Ebola Treatment Centres (ETCs) and Transit Centres (TCs) are filled with patients – almost 90 percent of whom turn out to be ill from something other than Ebola – new confirmed cases appear outside organisations' radar, seemingly out of the blue.

The chain of transmission

The number of new infections soared in March, passing from 26 to 72 per week over the course of the month.

Over the past few weeks, half of the people confirmed as positive had no connections with previously known Ebola patients. And, almost half of these new Ebola cases are only conformed post-mortem – meaning people die without the specialist care that could have helped them, despite usually visiting multiple healthcare facilities.

A solid grasp of the “chain of transmission” allows teams to identify early people who may be ill and admit them to care quickly. It also helps in understanding how the virus spreads and improves the chances of controlling the outbreak.

Taking no risks

Facing an uphill struggle on this front, the Ebola response system has adopted an exceedingly conservative approach to the management of new alerts:

People who present even the vaguest symptoms are hospitalised in dedicated centres to be tested, even when there is a low probability that they actually have Ebola.

“Most of the patients admitted in these centres have not been tested for Ebola yet. They may have symptoms of the disease, but these symptoms are shared by other health issues common in the region, including malaria,” says Natalie.

“What happens is that the majority of patients don’t have Ebola, but they end up spending two or three days in the centres before they’re allowed to leave.

"If they have an illness other than Ebola, they’re not necessarily being treated appropriately for it.”

Shrouded in mystery

The fear of being forcibly hospitalised adds to the poor perception of ETCs among the community:

These structures are associated with a deadly disease, a regime of isolation and the use of protective equipment that makes staff appear unrecognisable and intimidating.

Despite efforts to make them more accessible – such as the use of see-through partitions and closer proximity between patients and visitors – what happens beyond the entrances of ETCs remains shrouded in mystery for the community.

As a consequence, potentially sick people often do their best to avoid them – even if they suspect they might have contracted the disease.

The result is a vicious circle in which an individual's reluctance to be admitted to an ETC is met with increased determination by healthcare staff to make sure no suspect cases fall through the cracks, leading to yet more reluctance and mistrust from the community.

Identifying infectious diseases

“ETCs are specialised to treat confirmed Ebola patients, but people go to ordinary general health centres when they develop symptoms because that’s what they know, that’s where they’ve always gone to seek healthcare” says Natalie.

Health centres and hospitals, she points out, offer the assurance that someone will be treated for whatever illness they have; Ebola-dedicated structures don’t inspire the same confidence.

Meanwhile, local health facilities, with no access to on-site testing, find it almost impossible to decide which of their many patients that are showing symptoms of infectious disease should be referred to a specialist Ebola centre, and which should be treated for more common illnesses.

A gateway for Ebola

A damning side-effect of this is that poorly equipped healthcare facilities become a gateway for the virus, turning de facto into accelerators of the epidemic.

While health workers are largely protected by an unlicensed but promising vaccine (offered to frontline workers under WHO-approved protocol, and also available to contacts of confirmed cases), patient-to-patient transmission seems to be an alarmingly recurrent problem.

A patient that is admitted to a health centre for a case of malaria or pneumonia, or to give birth, may share a room or medical equipment with someone who is later confirmed as having Ebola.

As a week often passes by between the onset of the symptoms and the confirmation of the disease, an infected patient may have been in contact with many patients in multiple health facilities, making it almost impossible to trace all the contacts.

Finally, a contaminated health centre becomes a non-functional health centre, reducing access to healthcare for the wider population.

“We risk an explosion”

This disconnection between the Ebola intervention and the ways in which people seek healthcare has been a stumbling block so far.

It may have contributed to the persistence of the outbreak, as well as the fact that after a relative lull in the transmission the number of newly infected people has increased again - wiping out hopes that the epidemic might end soon.

“I think there’s a real risk to see a significant increase in cases,” says Natalie.

“If a cluster of the outbreak spreads to another large urban population, such as the city of Goma, we risk an explosion.”

A new strategy

How do we break this vicious circle? With a new strategy, according to Natalie, who mentions the work MSF is doing in Lubero, North Kivu, as a step in a new direction.

“Our approach there is to integrate the activity into the existing healthcare system: to help health centres in detecting signs of Ebola, along with other illnesses, and a level of hygiene that prevents the spread of disease among patients.

“Then, two scenarios apply. If a patient isn’t critically ill but might have Ebola, blood tests can be taken in the health centre or even at home.

“However, if they show signs of severe illness, they are sent to the hospital and a specially adapted isolation-resuscitation area - where we can treat other illnesses with similar symptoms, such as bacterial sepsis or severe malaria.

“During this initial management, we take a blood test for Ebola and send it to the nearest lab facility in Butembo.

"This way, we only admit patients to Ebola centres when we definitely know they have Ebola and we can make sure they will receive a level of care adapted to the severity of their illness.”

Limiting referrals to the ETC and offering more comprehensive and individualised care, says Natalie, will encourage people to participate in the Ebola response.

“We want people to understand”

Equally needed is a more effective message about the benefits of going to health centres as early as signs of illness appear.

“We want people to understand that whatever their illness, your outcome is always better if you get treated earlier,” says Natalie.

“It’s the same situation for Ebola as we see with septicaemia or malaria. If patients wait until they become very unwell before they seek treatment, then their chances of dying are higher.”

Should laboratory tests confirm that a patient has Ebola, adds Natalie, it should be made very clear that a quick transfer to a dedicated treatment centre to receive specialist care can increase chances of survival.

“Ebola is a very scary disease” concludes Natalie.

“It’s normal for people to be very afraid and not really understand the measures that are put in place to fight the spread of the virus. They don’t see how the current response benefits them and feel that it’s not working. They’re unable to make decisions about their own healthcare.

“We have to respond to that and try different approaches to manage both the Ebola epidemic and the healthcare of the community.”
