Epi Info™ 2015 Annual Report

Message from the Division of Health Informatics and Surveillance Director

Dr. Paula Yoon

In 2015, CDC’s Epi Info™ team made major contributions to support the agency’s mission to protect America from health, safety, and security threats, both here at home and abroad. The Epi Info™ team provided tools to support outbreak investigations, disease surveillance, monitoring of mass gatherings and data analysis and visualization projects. The team also conducted training sessions for more than 1,000 individuals across the United States and among our international partners.

Today, the Epi Info™ team continues to make enhancements to its suite of interoperable software tools to provide better utility for public health practitioners and researchers.

  • Epi Info™ for Windows had recent enhancements to its analysis and GIS functions.
  • Epi Info™ now extends desktop features to mobile devices and web-based platforms.
  • Epi Info™ is building enterprise grade solutions for large scale, distributed data collection.

I am proud of the accomplishments the Epi Info™ team has made to provide free tools that support epidemiology across the globe and the outstanding technical assistance and training that helps users deploy those tools to address a myriad of public health threats.

Epi Info™ At a Glance

What is Epi Info?

Epi Info™ is a public domain suite of interoperable software tools designed for the global community of public health practitioners and researchers and includes:

It provides for easy construction of data entry forms and databases, a customized data entry experience, and data analyses with epidemiologic statistics, maps, and graphs for public health professionals who may lack an information technology background.

How is Epi Info™ Used?

Epi Info™ is used for outbreak investigations; for developing small to mid-sized disease surveillance systems; as analysis, visualization, and reporting (AVR) components of larger systems; and in continuing education in the science of epidemiology and public health analytic methods at schools of public health around the world.

Epi Info™ Proved Value During Multiple 2015 Public Health Responses

Epi Info Team Members

Epi Info™ Virtual Hemorrhagic Fever (VHF) Application Helped Identify More Than 100,000 Suspected and Confirmed Ebola Cases
The Epi Info™ Viral Hemorrhagic Fever (VHF) application was used by CDC responders during the agency’s Ebola response in Guinea, Sierra Leone, and Liberia. The VHF database grew to contain data on more than 100,000 suspected and confirmed Ebola cases. In 2015, responders were aided by a data management and contact tracing tool for VHF that the CDC Epi Info™ team developed for use in Uganda in 2013.

Use of Epi Info™ Decreased Case Count of Salmonella Poona Outbreak in 40 States

In August 2015, CDC joined state public health officials and the Federal Food and Drug Administration (FDA) in investigating a multistate outbreak of Salmonella Poona infections potentially linked to imported cucumbers. Ultimately, the outbreak resulted in six deaths and illness reported by 907 persons in 40 states. Lyndsay Bottichio, an epidemiologist for the Division of Foodborne, Waterborne, and Environmental Diseases in CDC’s National Center for Emerging and Zoonotic Infectious Diseases (NCEZID) who helped investigate the outbreak, credited the use of Epi Info Web Survey (EIWS) with NCEZID’s ability to rapidly deploy their questionnaires and quickly gather needed data. Bottichio said, “The recent Salmonella Poona outbreak was solved and went to recall status in 16 days. This is practically record timing. We were able to do this because we used EIWS to deploy our questionnaires. We have continued to use this service as the outbreak continued and have about 400 responses. It made it possible for us to get a large amount of data from the states very quickly, then helped us determine if we should be looking at watermelon or cucumbers by running some quick frequencies. Had we used another system, this would have taken us many more days to weeks, leading to hundreds of more illnesses. You can see with the epi curve that our recall recommendation resulted in a huge reduction in the case count.”.

Innovation at Work

The CDC Epi Info™ Team Provided Customized Solutions to Organizations Across the Globe

The CDC Epi Info™ team developed innovative tools and provided customized solutions for external organizations. Significant accomplishments for 2015 include:

Epi Info™ Based Application for HIV Home Testing and Counseling in Namibia

  • The CDC Epi Info™ team, in collaboration with CDC Namibia, finalized an Epi Info™ based application and user manual for HIV Home Testing and Counseling to be used nationally in Namibia. The latest enhancements to the application include error checking and validation for over 600 data points based upon the United States President’s Emergency Plan for AIDS Relief (PEPFAR) requirements.

Epi Info™ for Web and Cloud and Epi Info™ for Mobile Used for Real-Time Analytics for Surveillance

  • Epi Info Web Survey shown on a tablet device

    The CDC Epi Info™ team assisted Brazil’s Ministry of Health with deployment of the Epi Info™ for Web and Cloud and Epi Info™ for Mobile. These two products were used for health surveillance data collection and real-time analytics for surveillance during the October 2015 World Indigenous Games in Palmas, Brazil.

Epi Info™ for Mobile Used for National Nutrition Surveillance

  • Epi Info Mobile Companion for Android

    The CDC Epi Info™ team assisted the Institute of Nutrition of Central America and Panama (INCAP) in Guatemala (at the request of NCCDPHP) with using Epi Info™ for Mobile for a national nutrition surveillance project. Data were successfully collected on mobile devices and INCAP requested that the CDC Epi Info™ team continue to provide support during 2016.

The CDC Epi Info™ Team Developed a Data Management System (DMS) to Evaluate the Effect of MenAfriVac Use

The CDC Epi Info™ team developed a data management system (DMS) for NCIRD’s MenAfriNet, which is a regional meningitis surveillance network in the meningitis belt of Sub-Saharan Africa, created to evaluate the effect of MenAfriVac use. In 2001, the Bill & Melinda Gates Foundation (BMG) established the Meningitis Vaccine Project (MVP) with a goal of eliminating meningitis epidemics in Africa. By late 2009, MVP had developed and licensed a new tool to fight these epidemics—a novel conjugate meningococcal A vaccine called MenAfriVac. The MenAfriVac vaccine was first used in mass campaigns in 2010, and since 2015, more than 100 million people have received it. The vaccine appears to reduce the risk of meningitis but the effectiveness of the vaccine needs to be evaluated further over time to verify this conclusion.

Epi Info™ Source Code Used To Develop a Mobile Device Application

The North Carolina Institute for Public Health (NCIPH) used Epi Info™ source code to develop the Collect SMART mobile-device application that is used to collect data in the field.
