Containing Ebola in West Africa with Technology: Overview and References to Explore


Ebola is a highly infectious and deadly disease. Symptoms include fever, sore throat, muscle pain, and headaches, and are followed by vomiting, diarrhea, rash, and internal and external bleeding1. The incubation period is between 2 to 21 days. It is deadly in 50% of the cases (on average). It is transmitted through direct contact with body fluids. There is no cure and patients are given fluids to reduce fever and stabilize blood pressure.

The Ebola outbreak in West Africa was first reported in December 2013 in Guinea. It is the deadliest occurrence of the disease since its discovery in 1976. The largest outbreak is centered in Guinea, Liberia, and Sierra Leone.

There are numerous examples on how technology is helping containg and fight Ebola – from radio, TV, toll free hotlines to social media, SMS solutions and mobile apps. In this article we provide references that will let readers understand how technology is used to contain and fight Ebola in West Africa. This article provides a list of possible use cases and describes some solutions in details, discusses the limitation of some solutions that do not rely on the users and context of the affected areas, and make some recommendations to consider in developing relevant and efficient solutions. Our conclusion are that: 1) while targeting the general population is crucial, solutions aiming at health workers and community leaders are also important as they can disseminate information; 2) SMS is still the most powerful technology to reach people at risk; and 3) there is a need of more collaborations between the actors who are proposing redundant solutions and not sharing message content and collected data.

Consequences of Ebola

Up to January 9th 2015, more than 800 people were reported as having died from the disease in six countries: Liberia, Guinea, Sierra Leone, Nigeria, Mali and the US. The total number of reported cases is more than 21,000. Considering the difficulty of collecting data, the World Health Organization (WHO) believes that these figures are underreported2. Finding and counting cases often require investigations on the field and avoiding stressing out and frightening people more than they already are. Cases can fall out of the official count at each step of the reporting process due to mistrust, poverty, lack of resources for health workers, and poor roads and infrastructures.

The latest WHO Ebola Report is available here:

The consequences of the disease are not only linked with health and deaths. The Ebola crisis slows down important services and local economy of affected countries. A UN World Food Programme (WFP) survey found that households in Kailahun and Kenema, two districts in eastern Sierra Leone are badly affected by the Ebola outbreak and struggling to meet their basic food needs3.

In addition, more than 5 million children in West Africa cannot attend school and emergency education measures are necessary to support and sustain school safety4,5,6.


There are numerous examples on how technology is helping fight Ebola – from radio, TV, toll free hotlines to social media, SMS solutions and mobile apps7,8,9.

Use cases
  • Diffusing prevention tips and educating about the disease (including two-way communications)
  • Locating and mapping infected areas to track the disease and propose actions
  • Developing communities of proactive health workers and citizens
  • Collecting, reporting and analyzing data in a digital form
  • Polling people in affected areas
  • Tracing all contacts that an infected person has been in touch with
  • Supporting infected persons during the disease and after recovery
  • Reporting data to labs and tracking health supplies
  • Educate on burial practices and coordinate burials of Ebola victims
  • Automated diagnostic of people infected by the disease
  • Etc
Discussion on the choice and impact of technology solutions

While we need technology, we can question some uses of technology and high tech solutions that do not consider the realities of the affected countries (e.g., the use of drones and social media)10. Better infrastructures are needed and Facebook, the Paul G. Allen Family Foundation, Cisco, EveryLayer and Inveneo are partnering to improve communications to fight ebola11.

It is important to have people and context of the affected countries at the core of the design of the solutions. It is not about technological prowess but technology that works! For example, 69% of people in Sierra Leone have mobile phones, but only 9% used 3G data. It is clear that mobile phones have a more important role to play than any other technology but mobile penetration is still low in rural and remote areas.

What solutions to propose where Internet penetration and literacy are low, use of smartphones is almost inexistent, rural areas are not covered by telecom operators, and people speak local languages different from English and French and do not use social media?

SMS is a powerful tool as it is available on every type of phone and people in the affected areas are still using basic phones without Internet access. SMS can be saved on phones and can be shared easily by people and health workers. However, they require literacy! Most SMS systems are only one-way, so they cannot be used to collect information directly from the general population or target group. More two-way communications are necessary.

There are more than 200 apps on Google Play that target Ebola12. We can categorize them as follows: emergency/disaster management, prevention, support for victims and survivors, tracking, and data collection. Their targets can be the general population and health workers. Considering the status of apps penetration in West Africa, apps for health workers would have more impact providing health workers are trained and equipped with smartphones.

The quality of the content of SMS and apps is very important. Content needs to be up-to-date, synchronized and developed with experts. There are more than 200 initiatives by NGOs and international organizations in the design of messages about Ebola to be sent to communities. This certainly implies replication of the same content and spamming targeted people. It is important for organizations to work together and design a database of Ebola messages as it was done for MAMA in maternal health13.

The use of Social Media is still limited in Africa. Facebook is the most widely used social network. The diaspora has an important role to play on social media in crisis situations by relaying crucial information to relatives in the affected areas10,14.

Collecting and analyzing data and mapping the disease are crucial. The US company, Magpi (, is helping to change the way data are collected and analyzed by implementing mobile data solutions in affected areas. More generally, it is important that all data related to Ebola are made available to researchers, organizations and developers to analyze and propose solutions to contain the disease15.

OpenStreetMap has been providing crowdsourced mapping services from the beginning of the Ebola outbreak16. Maps of the spread of the diseases, available health facilities, hostility towards health workers and other information are provided. OpenStreetMap permits a low granularity of information and maps areas that are not available on Google Maps.

  • Put users and contexts at the center of the design of solution (e.g., Internet penetration and local languages)
  • Promote solutions that work rather than technology prowess
  • Partner with experts from different fields (medical, public health, government, health geography and technology experts)
  • Develop solutions for users who are trusted by their communities (e.g., religious leaders and health workers)
  • Empower people to make them part of the solution (e.g., two-directional messages and people as health workers)
  • Privilege two-way communications
  • Synchronize data and provide up to date content in a timely manner
  • Design a database of messages on Ebola (e.g., MAMA for maternal health11)
  • Rely on, leverage and connect to existing tools (e.g., iHRIS health workforce information system)
  • Make all data about Ebola open to have researchers, organizations and developers
Examples of proposed solutions


  • The BBC launched an Ebola public health information service on WhatsApp, the biggest chat app in use in Africa. Audio and SMS alerts and images are sent to provide people with the latest public health information. MIXIT is also used to send public health information.

Data and maps


  • According to a study by the government of Sierra Leone, UNICEF and other partners, 96% of the households affected by Ebola are suffering from discrimination. A campaign, called #ISurvivedEbola, was launched to support Ebola survivors in all aspects of their life after the disease. Survivors can submit updates that are directly visible on social media and the dedicated web site.

Facebook app

  • Facebook created Safety Check, an app that lets people near the site of a natural disaster to know if their friends are safe. The app is activated in case of disaster or emergency situation.

Hackathons & events

Numerous universities and organizations around the world have organized hackathons where interdisciplinary teams of developers, designers, public health specialists, activists, and medical experts can work together to frame solutions to fight Ebola. One particularly noticeable initiative is targeting youth of Sierra Leone (e.g., secondary school pupils) who are out of school due to the outbreak17.
