Muganga Riposte

An epidemic is wonor loston the ground.

Riposte is the platform that tracks an outbreak in real time, coordinates the logistics it demands, and puts the community at the centre of the response for governments, health zones and the facilities that carry the load.

Report an Ebola alert

What the platform does

Three things, done together.

Separately, each already exists somewhere. Holding all three in one system, reachable from a phone on a thin connection, is where the difference comes from.

  • Track

    The outbreak in real time

    Cases are flagged where they are seen. Health zones, referral hospitals and provincial authorities see the same picture at the same moment, and every published figure carries its source and its date.

  • Coordinate

    The logistics that follow

    Protection kits, gloves, masks, isolation capacity, available teams requested from the ground, tracked on the network, and sent where the shortage is real rather than assumed.

  • Involve

    The community in the response

    The pharmacists and community reporters people actually go to first are on the network: trained, equipped, able to raise an alert. A response that excludes them gets cases hidden from it.

What Riposte tracks

Africa's active outbreaks, in one table.

Riposte is not an Ebola platform. It follows epidemic and syndemic events across the continent, with the source and date behind every figure. Here is what is active today.

The severity column is our own read not an official grading. It weighs case fatality, geographic spread and whether countermeasures exist. Formal declarations are shown separately.

Why Riposte exists

In Ituri, the hospital is not the first stop.

In Ituri, a lot of people do not go to the hospital first. They go to the pharmacy on their street, or the drug shop in the next village somewhere they already know, close enough to walk to, and not a place that will keep them.

That is not a failure to be corrected. The pharmacist is the person the community already trusts, and the person a sick family will willingly tell. Riposte does not ask that to change. It puts the pharmacist on the network.

Which means the person who first meets a case of Ebola stops being someone with no equipment, no training and no way to reach anyone and becomes the first node in the response.

The first thing we built

MugangaConnect

One network across everyone who touches the response pharmacists and drug shops, health centres, the referral hospitals, the zone de santΓ© and the provincial authorities. Cases go up it. Kits and training come back down it.

  • 01

    The case is flagged where it is seen

    A pharmacist facing a patient who should not be moved raises a flag from a phone, in seconds. No form to post, no weekly return, no waiting for someone to visit.

  • 02

    The health centre and hospital see it at once

    The flag lands with the health centre, the health zone team and the referral hospital in the same moment. What used to surface in a report at the end of the week surfaces immediately.

  • 03

    It is reported on to the health zone and the authorities

    Health centres, the referral hospital, the zone de santΓ© and the provincial authorities sit on the same network. Nobody has to be told twice, and nobody finds out last.

  • 04

    Equipment and people go back out

    The facility that actually has protective equipment and isolation capacity dispatches to the patient rather than the patient travelling, and infecting people on the way.

More than patient details

Three things move on this network, not one.

  • Cases

    Alerts, from the people who see them first

    A critical case raised at a village pharmacy reaches the health centre, the referral hospital and the zone de santΓ© at the same instant with the location, and with what the provider can see.

  • Kits

    Gloves, masks and full protection packages

    Basic kits and full protective packages are requested, issued and tracked on the same network. A provider can report that a kit is finished before running out becomes the reason a patient is turned away.

  • Training

    Elimu, pushed to every provider on the network

    The referral hospital has run outbreak responses before. Most of the people meeting patients first never have. Elimu carries that knowledge out to them as short video modules, in the languages they work in.

Elimu Β· the learning layer

Elimu the training travels with the network

Every provider connected through MugangaConnect gets the same video training, produced with the referral hospital and updated as the outbreak changes. It is built for a phone, on a thin connection, by someone who may be standing in front of the patient right now.

What providers are shown

  1. 01Recognising a case before it is confirmed
  2. 02Putting on and taking off protective equipment safely
  3. 03Isolating a patient until a team with proper gear arrives
  4. 04What to do when you have no equipment at all
  5. 05Safe referral, and safe burial practice
  6. 06Reporting a kit that has run out

β€œA virus the community is actively fighting does not get to become an epidemic.”

Every outbreak response here eventually runs into the same wall: people hide cases because coming forward costs them something. Riposte is built the other way round around the people the community already goes to, given the gear, the training and the standing to help. When the response includes the community, there is far less for the virus to move through.

The model

What the model is, and what it is not

  • It learns from the cases that exist

    Riposte converts existing case records into machine-readable form as the outbreak runs, so the picture gets sharper week by week instead of being frozen at whatever was digitised at the start.

  • It is grounded in Zaire-strain data

    Almost all the historical Ebola case data in the world is Zaire ebolavirus. That is what there is to learn from, and it is what our models are grounded in. This outbreak is Bundibugyo a different species, with a different fatality profile and no licensed vaccine.

  • We say so on the output

    A model trained on one strain and applied to another is useful, not authoritative. Riposte states that where it matters, and nothing it produces replaces the judgement of the clinician holding the case.

Built with

Panzi Hospital, Bukavu.

Riposte is built alongside Panzi Hospital the referral hospital founded by Dr Denis Mukwege and the health zone teams it works with across South Kivu and Ituri. The clinical judgement in this platform comes from people who have run outbreak responses here before.

The live deployment

DR Congo Bundibugyo Ebola, with Panzi Hospital.

Riposte was built during this epidemic, alongside the people fighting it. This is the deployment that shaped the platform and the rest of this page is what it does on the ground.

What is known

Why this strain is different.

Bundibugyo is one of the less common Ebola species. The tools built for the Zaire strain the licensed vaccine, the approved antibody treatments were not made for it.

Pathogen
Bundibugyo ebolavirus (BDBV). One of six known ebolavirus species.
Vaccine
There is no licensed vaccine for the Bundibugyo strain. A Moderna candidate entered a first-in-human trial with CEPI backing, and WHO advisers have said the licensed Ervebo vaccine could be trialled in this outbreak.
Treatment
No approved antiviral exists for Bundibugyo. Care is supportive fluids, electrolytes, and management of fever and pain. Early intensive supportive care improves survival.
Scale
The US CDC describes this outbreak as spreading substantially faster than previous Ebola outbreaks, and as the second-largest on record.
How it spreads
  • Direct contact with the blood or body fluids of someone who is sick or has died
  • Contact with surfaces and materials contaminated with those fluids
  • Burial practices that involve direct contact with the body
  • Contact with infected wild animals, including bats and non-human primates
Outside the region
Three imported cases have been reported outside Africa two in Germany, one in France.
