Over 11000 people died during the 2014-2016 Ebola outbreak in West Africa.The virus hopped between Guinea, Leone, Nigeria and Liberia, before making its way to the UK and US. But what would have happened if analysis and machine learning stepped in to help solve the problem, asks ANESHAN RAMALOO of SAS.
But what if we could have predicted the outbreak months before it happened, buying us time to take proactive measures to contain it and curb its spread?
With access to overwhelming volumes of data, the computational power needed to store and analyse this data in real time, and sophisticated algorithms that can find patterns in the data and alert authorities to health problems before they become, well, problems, pandemics don’t have to be as devastating as they have been in the past.
In fact, with advanced data analytics, we can better manage any disease – long-term, short-term or pandemic – resulting in better patient treatment, more efficient use of resources and cost savings.
It’s been done before.
By analysing data from social media, blogs, online forums and keyword searches, we were able to predict the 2012-2013 US flu season three months before the Center for Disease Control (CDC) issued its first official warning.
Imagine the impact if the same analytical power was applied across the entire healthcare spectrum – not only on a national and global level, but right down to the individual level.
In the past, health workers relied on manually intensive, paper-based systems to record infections and deaths during disease outbreaks. Not only was it easy for errors to slip through but because the data was anecdotal and historical, authorities did not get a complete understanding of the reach and impact of the outbreak.
During the Ebola outbreak, the CDC adopted a mobile data collection system that enabled health workers to instantly submit information to a database via text messages. This low-cost method of information gathering not only resulted in fewer errors but also allowed analysts to draw up detailed maps of population movements, which made it easier to understand how the disease was likely to spread, and where to set up treatment centres.
While this was certainly an improvement on the paper-based systems of old, the drawback was that mobile data was historic and did not provide researchers with the ability to track developments and population movements in real time.
But mobile phones are just one source of data. Today, health authorities can overlay thousands of data sources – including social media, health and physician reports, keyword searches, media reports, transactional data from retailers and pharmacies, airline ticket sales, geospatial data and more – to not only better manage diseases and outbreaks when they do happen, but to see them coming months in advance – and what could happen if we don’t act on the information.
By mining structured and unstructured data, we can track the movements of infected populations and who they come into contact with; we can measure the success of containment policies, education campaigns and treatments – and what to do if they’re not working; we can determine the effect of weather and other environmental factors on the spread of diseases.
Never before have we been able to act on information to save lives, not just during pandemics but through better understanding and treatment of diseases.
Until now, standard treatments for diseases such as cancer and HIV have been applied to all patients, regardless of their unique profiles and with little understanding as to why some people respond well to certain treatments and others don’t.
But by analysing and creating ‘medical maps’ of individuals that take into account their anatomy, physiology, DNA, RNA and chemical composition, doctors can prescribe personalised treatments that have a greater chance of success.
There are many other benefits of data analysis in healthcare:
· Personalised treatment can result in fewer hospital admissions and can produce faster results and better experiences for patients;
· By better understanding the impact of lifestyle and diet on health, medical aid providers can educate their members with the aim of improving their health, which could result in cost savings for both the provider and the member;
· Governments can use data to develop proactive approaches to protecting and promoting public health, to prioritise services and to find ways to cut costs so that they can provide healthcare to more citizens.
· By sharing data and results from clinical trials and combining that data with academic, patient and industry data, medical researchers can better understand the genetics of viruses, why some strains are more deadly than others, and why some people are more resistant to viruses. This could spark innovation and generate new insights that ultimately improve treatment and outcomes.
AI and machine learning
As the use of intelligent algorithms, machine learning and natural language processing becomes more entrenched in advanced data analytics, technology will increasingly supplement the skills of humans to produce faster and more accurate medical diagnoses.
Machine learning can extract valuable insights from unstructured data like clinical notes and academic journals to provide even larger datasets that will transform the medical industry into a proactive front against diseases.
There are plenty of doomsday theories about how machines will supersede our intelligence and rise against us. But there aren’t enough stories about the potential of data analytics, AI and machine learning to supplement human skills and knowledge to drastically changes lives for the better – and even save them. Right now, it’s looking more likely that machines will actually help us to live longer – and I don’t know many people who would object to that.

Africa gets broadband boost
ITU and Nexpedience, a supplier of proprietary point-to-multipoint broadband infrastructure, are partnering to bring broadband access to Africa.
Under the terms of the deal, Nexpedience will provide 180 new Expedience base stations worth USD 1 million, to be deployed in six nations across the continent. The first nation to benefit from the new infrastructure is Burundi, with deployments also planned for Djibouti, Burkina Faso, Mali, Rwanda and Swaziland.
Designed to withstand extreme meteorological conditions and capable of providing up to 32 kilometres of sector coverage, Nexpedience’s base stations have been specifically designed for rural deployment.
ITU’s Wireless Broadband Network in Africa project aims to develop and implement wireless broadband connectivity and applications that will provide free or low-cost digital access for schools, hospitals, and under-served populations in rural and remote areas Africa-wide.
At the signing of the agreement in Geneva, Brahima Sanou, Director of ITU’s Telecommunication Development Bureau (BDT) emphasized the need to make developing countries part of the global broadband revolution: ‚”This partnership represents another important element in ITU’s efforts to bring broadband technology to the world even in the poorest nations. I am confident that this new partnership will accelerate broadband uptake right across the African continent, bringing the power of high-speed connectivity to users everywhere, from big cities to small villages.‚”
Kiriako Vergos, CEO of Nexpedience said: ‚”Giving access to broadband technology to underserved populations in Africa is of great importance to us. There are enormous benefits to be derived from a ‚’broadband-seed’ deployment strategy, and we decided to partner with ITU because we know that the organization has the team in place to get it done.‚”
ITU Secretary-General Dr Hamadoun Tour√© said the new agreement is a ‚”major step forward in getting Africa connected‚”. Dr Tour√© led the establishment of the Broadband Commission for Digital Development in 2010, which has the aim of putting broadband at the heart of the global development agenda.
Nokia backs tech hubs for developing world
Nokia, AppCampus and infoDev are collaborating with mobile innovation hubs across Africa, Asia and Latin America to act as scouts for local talent.
Nokia, AppCampus and infoDev, a global innovation program of the World Bank, have announced a collaboration with mobile innovation hubs across Africa, Asia and Latin America – a move that will empower these hubs to act as scouts and agents for local talent, fast-tracking their access to AppCampus funding.
AppCampus was established in 2012 as a mobile application accelerator program managed by Aalto University in Finland. With an 18 million euro joint investment between Microsoft and Nokia, the aim is to foster mobile application development on Windows Phone and any other Nokia platform.
The announcement earmarks part of that investment fund for twenty six awards per annum for the best mobile innovation ideas to be made via the mobile innovation hub network, starting with infoDev’s mobile application labs in South Africa, Kenya, Armenia and Vietnam, as well as mobile application laboratories in Egypt (TIEC), Nigeria (CC Hub) and Mexico. The value of each award ranges from 20,000 Euro (US$ 26,000) to 70,000 Euro (US$ 90,000) depending on the complexity of the solution or business model behind the idea.
‚”By working jointly with the mobile innovation hubs, we are able to connect more effectively with local developers in emerging markets and provide support in terms of funding, especially for locally relevant innovations,‚” says Pekka Sivonen, Head of AppCampus. ‚”Although the criteria to access the AppCampus funding remains the same, with ideas needing to be original, competitive and scalable, the advantage is faster processing and the mentorship provided by these innovation hubs.‚”
The hubs and mLabs will be responsible for scouting talent and vetting ideas to be submitted to the global pool. infoDev’s mLabs foster regional entrepreneurship, employment and competitiveness by providing open spaces where developers can find training, mentoring, technical expertise and access to financing. In a short time, mLab-supported startups have brought over 120 commercial apps to market The best new entries from this network will compete against each other each quarter for the available awards.
‚”Nokia, working closely with infoDev, has supported the establishment and operation of a number of mLabs across emerging markets in support of local developers,‚” says Jussi Hinkkanen, vice president corporate relations for Nokia Middle East and Africa. ‚”The AppCampus collaboration showcases our commitment to strengthening the growing mLab network around the world and infoDev’s vision of supporting emerging market entrepreneurs in conquering local, regional and global markets‚”.
The official launch of the program took place during the mobile stream at the Global Forum on Innovation & Technology Entrepreneurship in East London, South Africa, organized by infoDev and the South African Department of Science & Technology. A key theme of the Forum is how innovation can lead to high-growth entrepreneurship which creates sustainable jobs. Valerie D’Costa, infoDev’s Program Manager says, ‚”The AppCampus initiative fits with the philosophy of infoDev of supporting innovative entrepreneurs from developing countries. We want to support those who can excel with some level of mentorship, skills training and seed financing. We provide potential job-creators better access to markets, which is what we are all about.‚”
