Wah Wah LwinParticipantHow IT could assist Outbreak Investigation Process?
Verification and Preparation
1. Establish the existence of an outbreak: by developing real-time dashboards to display case trends over time and place, as well as notifying authorities about unusual surges in cases.
2. Verify the diagnosis: through electronic laboratory reporting to public health authorities and relevant stakeholders, enabling timely data exchange across healthcare settings and supporting decision-making processes.
3. Prepare for field work: by using digital tools to collect field data and integrating GIS mapping to identify hotspots, allowing fast and secure information sharing.
Describe the outbreak
4. Construct a working case definition: by using collaborative digital tools to draft, review, and revise case definitions, which can then be easily shared with the technical working group without requiring in-person meetings.
5. Find cases systematically and record information: by using digital case investigation forms on mobile phones, tablets, or computers for faster reporting, synchronized with a central database so that public health officials can promptly review and make further decisions.
6. Perform descriptive epidemiology: by creating data visualizations and GIS maps to identify case patterns, trends, and clusters through interactive dashboards.
Hypothesis & Testing
7. Develop hypotheses and analytical studies: by applying digital data analysis and statistical tools to explore correlations or associations between cases and possible contributing factors. In addition, IT can support data collection through digital surveys and assessment forms for further analysis.
Response & action
8. Implementation of control measures and follow-up: by using automated communication systems such as SMS alerts and emails to inform affected communities about control and preventive measures. IT can also help create dashboards to monitor the progress of interventions and follow-up actions.
9. Communication including outbreak report: by generating automated data summaries and dashboards for stakeholders, and sharing accurate information with the public via social media platforms. At the same time, IT can assist in monitoring social media behavior to detect and address misinformation in real time.
In addition, IT can support the overall outbreak investigation process by enabling efficient data exchange among stakeholders and decision-makers, minimizing data errors, enhancing efficiency, ensuring scalability, and strengthening data security and control.

Hteik Htar TinParticipantVerification and Preparation Stage, there are 3 following steps to do.
1. Establish the existence of an outbreak
2. Verify the diagnosis
3. Prepare for field work
To verify the outbreak, the field team can report the data within short time and the response team can check whether it is over alert line or not by comparing the former database. The collected data in the central server will provide epidemiological information and can be used in authorization to mobilize the rapid response team. In preparation of field work, the documentation for knowledge and laboratory data can easily be extracted by information technology.
In describing an outbreak stage,
4. Construct a working case definition
5. Find case systematically and record information
6. Perform descriptive epidemiology
For case finding and line listing, the health information system will provide the fast and valid data to analyze by using GIS technology and can present by data visualization technology to monitor the distribution of the diseases. This can support the response team to start the prevention and control measures. Information technology can also provide the working case definitions and epidemiological analysis in real time.
Hypothesis and testing stage require data to perform the interview for population.
7. Develop hypothesis
8. Analytical studies to test hypotheses
9. Special study (environmental study, laboratory study)
If information technology has database of population and geographical area, it can support whether to do environmental study or laboratory study. We can create heatmap for the outbreak area and can-do contact tracing and find point of source for infection. If the information system has interoperability with other systems, we can detect the causal agent (emerging or re-emerging) and alert others to prevent the pandemic spread.
Response and action stage:
10. Implementation of control measures and follow up
11. Communication – including outbreak report
By using information technology, we can use dissemination tools for control measures such as text messaging and chatbots, wearable devices for contact tracing and follow up. For public awareness and stakeholder advocacy, we can announce the risk communication measures through dashboards and mass media with data visualization techniques.-

ParticipantI agree with the point that text messaging and chatbots can be hugely useful nowadays, given the way of our communication in this era. Public health authorities can use these tools to deliver messages to people instantly. Also, IT devices can be useful in the reverse direction in that they aren’t only for communication but also for monitoring the effectiveness of the measures implemented.

Jenny BituinParticipantHere are some examples of how information technology was applied to assist in the outbreak investigation process:
1. Verification and Preparation
The Early Warning, Alert and Response System (EWARS) application of WHO can be used to improve disease outbreak detection in emergency settings, such as in countries in conflict or following a natural disaster. The app can be used to collect data from various sources, such as healthcare facilities and the community. Standard alert thresholds for a disease can be programmed into the app, and when the threshold is exceeded, it will send an alert to the surveillance officer.2. Describe the outbreak
Spreadsheet applications such as Microsoft Excel can be used in making a line list – a table containing basic information on each case (Unique ID number/case identifier, age, type of case, sex, etc.). A line list allows for organization of information and provides an overall picture. This will help in the creation of descriptive statistics and epi curve.3. Hypothesis and testing
For analytical studies to test hypotheses, OpenEpi can be used. It is a free and open source software that provides statistics for counts and measurements in descriptive and analytic studies, stratified analysis with exact confidence limits, matched pair and person-time analysis, sample size and power calculations, random numbers, sensitivity, specificity and other evaluation statistics, R x C tables, chi-square for dose-response, and links to other useful sites.4. Response and Action
The UK Health Security Agency (UKHSA) shares public health data (mostly from England and sometimes other UK nations) via the UKHSA Data Dashboard. This dashboard covers a range of topics such as respiratory viruses, healthcare-associated infections and antimicrobial resistance that inform public health decision making in England. It was developed to cater to different users, such as members of the general public, public health professionals, policy makers, and media. -

Yin Moe KhaingParticipantInformation technology plays a crucial role in assisting the outbreak investigation process by enhancing data collection, analysis, communication, and decision-making at each stage. During the initial step of establishing the existence of an outbreak, electronic surveillance systems are used to monitor disease trends and detect abnormal increases in cases. These systems allow for real-time data collection and automated alerts, which help identify outbreaks quickly.
In the step of verifying the diagnosis, information technology supports laboratory confirmation through Laboratory Information Management Systems that record, track, and share laboratory test results efficiently. Electronic medical records (EMRs) also enable healthcare professionals to verify diagnoses remotely and ensure data accuracy.
When defining and identifying cases, electronic case reporting systems and mobile data collection tools such as KoBoToolbox assists field investigators in capturing standardized data directly from health facilities or communities. These tools improve the accuracy and timeliness of case finding, even in remote areas.
In descriptive epidemiology, IT applications such as Epi Info, Excel, and Geographic Information Systems (GIS) are used to analyze data according to time, place, and person. GIS helps to map cases geographically and visualize clusters, providing insights into the spatial distribution of diseases. Similarly, analytic and visualization software such as Tableau or Power BI helps to identify patterns and generate hypotheses about the possible sources and transmission routes.
During hypothesis testing and evaluation, statistical software support the analysis of relationships between exposures and disease outcomes.
When implementing control and prevention measures, information technology enables effective communication through mobile applications, SMS alerts, and social media platforms. Decision-support systems also provide real-time recommendations for interventions based on current data trends. Finally, during the step of communicating findings, digital dashboards, online reporting tools, and interactive data visualizations allow health authorities to present results clearly to policymakers, healthcare providers, and the public.
In conclusion, the application of information technology in outbreak investigations enhances the efficiency and accuracy of public health responses. It enables rapid data collection, real-time communication, and evidence-based decision-making, which are all essential for timely control of disease outbreaks.
