Africa's eHealth needs stepping up to fight Zika
Zika’s not new to Africa. WHO’s Zika virus factsheet says “Zika virus is an emerging mosquito-borne virus that was first identified in Uganda in 1947 in rhesus monkeys through a monitoring network of sylvatic yellow fever. It was subsequently identified in humans in 1952 in Uganda and the United Republic of Tanzania.”
It maybe that Zika’s taken a step up. The Centers for Disease Control and Prevention (CDC) says “Local mosquito transmission of Zika virus infection (Zika) has been reported in Cape Verde. Local mosquito transmission means that mosquitoes in the area are infected with Zika virus and are spreading it to people.” It’s issued a travel warning.
Almost 0.5m people live in Cape Verde, off Western Africa. The BBC says about 7,000 people, 1.4% of the population, are suspected of being affected, including 180 pregnant women. An epidemic can be defined on a smaller incidence than this if a disease’s spread is rapid, such as within a fortnight.
While many people infected with Zika don’t become ill, people who do usually have mild illness with symptoms that last for several days to a week. In this setting, the effect of unborn babies is a bigger concern. Whether Zika in Cape Verde matches this is somewhat academic. Its seemingly sudden incidence in an African country seems more concerning.
An eHNA post set out the roles of eHealth in dealing with Zika. Now’s the time to invest in them.

Five countries comprise Africa's CDCs
The African Union (AU) has nominated five countries to host Africa Centres for Disease Control (ACDC). Olawale Maiyegun, Director of Social Affairs at the AU Commission, explains that the centres will be the Regional Collaborating Centres (RCC) for the AU’s disease control role. The countries are Nigeria, Gabon, Egypt, Zambia and Kenya, says an article in All Africa.
The countries are spread across West, East, North, South and Central Africa, ensuring effective representation and geographical spread. The concept was approved in 2015, with a mandate to each of the five sub-regions to nominate one country as their collaborating centre. AU representatives will travel to each of the nominated countries to ensure that institutions being established comply with the criteria in article 26 of the ACDC statutes.
Following Nigeria's success in containing epidemics like Ebola and Lassa Fever, the AU has given the country clearance to become am ACDC. It followed findings of the AU on site assessment of Nigeria's CDC conducted by a team of experts. The centre will act as the collaborating centre, making Nigeria the hub of research and disease surveillance in West Africa and a regional collaborating centre for Africa.
There’s no doubt that Ebola changed the way African now value surveillance. It’s a vital tool in the fight against these types of diseases and epidemics. If such a system and network had been available at the start of the Ebola outbreak, thousands of lives could possibly have been saved. The epidemic showed that prevention and control of disease outbreaks needs coordinated action and greater national, regional and international collaboration.
With many countries exploring the role of eHealth to strengthen their responses and surveillance, the research hubs and CDC centres will play a pivotal role. They can help prevent further outbreaks on the continent by identifying the locations of disease early, by sharing data and communicating properly with regional partners, neighboring countries and the AU to ensure coordinated efforts and provide data and analytics to help make informed decision.

Egypt to launch new digital disease outbreak hub
Disease outbreaks stress Africa’s health systems. Better controls are needed, and a new control hub is starting up.
A new disease control hub is set to be launched in Egypt to extend across Africa. It’ll use technology to trace and control diseases, predict outbreaks and engage communities in affected areas across Africa, says an article in IT News Africa. The African Health Data and Disease Control Hub (AHDCH) is an initiative by the Government of Egypt through the Egyptian Agency of Partnership for Development (EAPD), with the Association of Friends of the National Cancer-free Initiative (AFNCI) as its implementing partner and Microsoft providing technology support for the platform development.
The initiative comes in-line with the African Union’s call for an integrated and innovative effort to improve prevention, detection, and response to public health threats. The initiative is being launched at this year’s Africa 2016 Forum in Egypt. The AHDCH concept is in response to the 2014 Ebola outbreak in West Africa, which affected more than 20,000 people, bringing devastation to several West African countries. The epidemic showed that prevention and control of disease outbreaks needs coordinated action and greater national, regional and international collaboration.
Better cooperation and regional communication was emphasised by Dr Ousmane Ly at the Africa Healthcare Summit in London on the 17 to18 February. He believes eHealth and digital technologies are key to monitoring disease outbreaks and could have played a major role in curbing the spread of Ebola.
The hub will include a state-of-the-art virtual platform and will leverage Egypt’s recent advancements in ICT and data infrastructure, its commitment to the healthcare, pharmaceutical and environmental industries, and its capacity development and training expertise. It hopes to be a one-stop solution for all African countries, providing a nationwide directory of diseases, prevention methods, medical facility maps, vaccinations and medications. In addition, it will publish government efforts, news and campaigns, as well as provide communication tools to reach out to African citizens and raise awareness. The initiative is open for collaboration and contribution by various relevant national, regional and international organisations.
“There is a lot of momentum and enthusiasm at both regional and international levels for a disease control hub, following the Ebola outbreak,” says Ambassador Dr. Hazem Fahmy, Secretary General of EAPD, leading sponsor of the initiative. “The spread of diseases poses a threat to African stability, growth and international security. The AHDCH aims to play a primary role in disease control, enhancing the quality of life of citizens in affected areas, and helping African countries achieve their Sustainable Development Goals around health and the environment.”
“We are using our cloud platform to make the AHDCH a central portal, where governments, policy makers, non-profits, researchers and other organisations from across Africa can collaborate on disease control,” says Khaled Abdel Kader, General Manager of Microsoft Egypt. “Through Microsoft’s Azure for Research Initiative, researchers will be able to take full advantage of the power and scalability of cloud computing for collaboration, computation, and data-intensive processing.”
AFNCI will provide customised training and manage the hub’s day-to-day operations, including collecting data, generating reports and maintaining an active user community. Completion of the hub is planned for December 2016, with a roll-out over a period of three years to ensure its sustainable functioning, funding and quality performance.

How can eHealth help against Zika?
With lingering concerns about Ebola, what should Africa do about Zika? While it’s less damaging than Ebola, its effects on some population groups, such as pregnant women and their babies, are very serious.
WHO is supporting countries to control Zika virus disease with seven activities:Define and prioritise research into Zika virus disease by convening experts and partners Enhance surveillance of Zika virus and potential complications Strengthen capacity in risk communication to help countries meet their commitments under the International Health Regulations Provide training on clinical management, diagnosis and vector control including through a number of WHO Collaborating Centres Strengthen the capacity of laboratories to detect the virus Support health authorities to implement vector control strategies aimed at reducing Aedes mosquito populations such as providing larvicide to treat standing water sites that can’t be treated in other ways, such as cleaning, emptying, and covering them Prepare recommendations for clinical care and follow-up of people with Zika virus, in collaboration with experts and other health agencies.
WHO’s factsheet sets out the diagnosis, prevention and treatment arrangements for Zika. Diagnosis by serology can be difficult because the virus can cross-react with other flaviviruses such as dengue, West Nile and yellow fever. sharecare, a website, describes why people and countries should pay attention to Zika and act to avoid it.
While it may not be at epidemic proportions in parts of Africa, can eHealth be deployed to help? Some of the eHealth lessons from Ebola seem relevant. With no vaccine available for Zika prevention, eHealth services for vaccination and immunisation won’t be needed initially, and maybe for some time. eHealth initiatives could include:Data collection, data bases and registries, and analytical tools for surveillance Risk communication plans using mHealth seem a valuable initiative Mapping Aedes populations and behaviour Supporting laboratory testing and results reporting can help too Clinical Decision Support (CDS) for treatments and follow-ups offer a way to achieve consistency across numerous locations and easy updates.
All these have value for health and healthcare, so eHealth initiatives for Zika should be pursued in this context. They can help to spread affordability challenges, and more importantly, avoid the inefficiencies of paper trails. However, this latter goal relies on good eHealth.

Does WHO need better surveillance data?
In January this year, WHO set up an independent Ebola Interim Assessment Panel. Four important themes in its extensive report are relevant for eHealth.The Ebola outbreak started in 2013, but a Public Health Emergency of International Concern (PHEIC) under the International Health Regulations 2005 was not declared until 8 August 2014 There are disincentives for countries to report outbreaks quickly and transparently The outbreak was particularly challenging because of the characteristics of the virus, and healthcare systems and public health infrastructure in affected countries were extremely fragile, suffering from structural weaknesses, inadequate surveillance and few laboratories Messaging needs to be continuously refined so as to be responsive to the changing epidemiological situation.
These are all activities where eHealth can help. Does the report change the eHealth priorities for Africa, some African countries? The report emphasises how WHO can be changed to be more effective, there’s also an onus on countries to improve their information and communication. Investment in mHealth, surveillance, primary care, diagnostics and general eHealth skills could help.
The head of the panel was Dame Barbara Stocking. She was the chief executive of Oxfam, a leading aid charity. She was also a senior manager in England’s NHS.

The Ebola fight needs better surveillance
The awful tragedy of Ebola seems to be slipping beyond grasp. President Obama has now urged world leaders to enhance disease surveillance. It needs to operate on a large scale. iHealthBeat has set outa few eHealth initiatives that could help.
The US is appointing former White House CIO Steven van Roekel to lead the government’s use of technology to combat Ebola. His role will build on several eHealth initiatives already in place.The USA’s Center for Disease Control and Prevention (CDC) has deployed health workers with an app to track outbreaks and an automated data analysis tool that helps model and predict potential disease transmission A team of researchers is working with the Department of Defense to track Ebola, by using data from mobile phones and social media Virginia Bioinformatics Institute’s Network Dynamics and Simulation Science Laboratory has researchers leveraging new data sources from mobile phones social media to help to track the virus #HackEbola allows researchers to compile and analyse data from various local sources and post the digitised data online.
When the Ebola outbreak is finally vanquished, one of its legacies should be a vastly enhanced and modernised surveillance infrastructure for Africa. It’s just a great pity that Ebola is part of the price.

Surveillance strengthening takes off in Rwanda
Africans have been thinking a lot about infectious disease recently, with the Ebola death toll rising and infection spreading. Many countries are exploring roles for technology to strengthen their response. eHNA’s had pieces on work in Guinea and Liberia, a UNICEF platform and other global efforts.
An electronic integrated disease surveillance and response (eIDSR) system implemented last year in Rwanda is another example. It was built by Rwandans, led by Rwanda Biomedical Centre (RBC) working together with private company Voxiva. By April 2013 it was in most Rwandan district hospitals and health centres. Maria Kaitesi wrote a piece about it for allafrica.com.
Dr Kizito Kayumba, a Director at Voxiva, says this technology will help to ensure timely delivery of information to all health facilities, especially if there is a likely outbreak of disease. He said it helps to “contain and investigate potential outbreaks detected automatically in the electronic system. More than 1,000 health officials and staff have been trained to use the new technology,” and it’s being shared throughout countries in the East African Community.
The system uses the web, mobile phones and PCs, to help speed up the collection of information and its electronic sharing with all health facilities. This allows a rapid response to new threats.
“The paper based disease surveillance system reporting was causing late and incomplete reporting, difficulty in identifying outbreaks rapidly and challenges getting current and complete information to respond to outbreaks and to limit their spread and fatality. The new electronic system has turned this situation around,” said Dr. Thierry Nyatanyi, Director of Epidemics and Infectious Diseases Division at RBC.
In Kigali in March 2013 Rwanda’s Minister of Public Health and Primary Health, Dr Anita Asimwe said, “As far as I am aware, eIDSR is unique technology which has improved timeliness and completeness of reporting and helped officials detect outbreaks rapidly, investigate them and mount a quick response within the country and across our borders.” She’s well aware of the potential for this type of innovation to improve healthcare and save lives.
There’s no doubt many African ministers are looking for these types of solutions, and skills and resources to implement them effectively, to be part of the numerous efforts needed to halt Ebola’s menacing march.
