Epidemic Intelligence in Asia-Pacific

Strengthening early threat warning in the region

Timely disease notification to World Organisation for Animal Health (WOAH) is essential for global health security, yet reporting challenges persist. Funded by Australian Department of Agriculture, Fisheries and Forestry (Australia DAFF) under WOAH’s 7th Strategic Plan (WOAH 7SP), this initiative aims to enhance early disease detection in the Asia-Pacific region by identifying and breaking down barriers to both terrestrial and aquatic disease reporting. By delivering targeted solutions to improve World Animal Health Information System (WAHIS) data collection, information sharing, and regional communication, we enable WOAH Members and partners to respond rapidly and effectively to emerging health threats.

The Active Search Team for Asia and the Pacific region (AST Asia-Pacific) was established to proactively detect early signs of regional disease threats. Utilising the WHO’s Epidemic Intelligence from Open Sources (EIOS) system, the AST Asia-Pacific continuously analyses online information as part of its active search activity (‘rumours tracking’ activity). When potential outbreaks are identified, the team reaches out to relevant countries and territories in the region to verify crucial news signals.

Operating under the guidance of WOAH headquarters, AST Asia-Pacific works closely with the World Animal Health Information Department (WAHID) and epidemiologists from the Data Integration Department (DID). All non-official intelligence gathered by AST Asia-Pacific is systematically cross-referenced with official data in the WAHIS. While EIOS is the primary tool for the regional team (at present), WOAH’s global epidemic intelligence network is multifaceted, integrating platforms such as the Global Early Warning and Response System (GLEWS) for zoonotic diseases.

Why timely information matters

Real-time surveillance matters because of what can happen when information is not shared in a timely and accurate way. Slow information has consequences well beyond the animals affected.

Zoonotic spillover to humans
Many animal diseases are zoonotic and can spill over to humans.
Amplified spread and economic consequences
Undetected outbreaks can rapidly infect an entire region.
Trade restrictions
Failure to report can lead to trade restrictions.
Misinformation and disinformation
Inaccurate information can spread, both unintentionally and deliberately.
Ecosystem and wildlife disruption
Diseases can spill over to wild populations.

Two ways to gather epidemic intelligence

NON-OFFICIAL SIGNALS
Event-based surveillance
Looking for early warning signs
What it is
Ad hoc gathering of information about potential health events, through media monitoring on internet-based epidemic intelligence platforms.

The Active Search Team uses both. Signals found through EIOS are cross-referenced with official data in WAHIS.

How active search works

The active search process at a glance

In brief, the process has three stages: collect, analyse and communicate. The detailed workflow follows below.

1 Data collection›2 Analysis›3 Communication
1Data collection
Twice weekly, through digests
  • The Active Search Team Asia-Pacific gathers information from online resources: news articles, social media and official reports.
  • Information is collected through EIOS.
2Analysis
  • The team analyses the data to identify potential disease events of interest.
  • It then assesses their risks.
3Communication
  • Information is shared internally to raise awareness and enable informed responses if needed.
  • Relevant news is shared with WOAH Members and territories for clarification.
  • If needed, based on the detected news signals, Members submit official notifications to WAHIS.

A robust, four-step active search procedure

To transform open-source data into validated, actionable epidemiological intelligence, the AST Asia-Pacific applies a systematic workflow:

Open-source data
1
Search and identification
Routine screening of thousands of open online feeds utilising the EIOS platform.
2
Authentication
Cross-referencing non-official intelligence with official data in WAHIS to identify discrepancies.
3
Triage
Evaluating the epidemiological relevance, urgency and potential impact of the detected threat.
4
Immediate notification
Proactively engaging with the relevant countries and territories to verify crucial news signals and accelerate official reporting.
Validated, actionable epidemiological intelligence

Regional engagement and ‘One Health’ collaboration

  • Advancing the ‘One Health’ Mandate: WOAH plays an active role in the WHO-led EIOS initiative, leveraging open-source data and maintaining close operational links with partner organisations—including the FAO, WHO, INTERPOL and WOAH Reference Centres—for a unified, all-hazards approach to threat detection.
  • Expanding Linguistic Sensitivity: The AST Asia-Pacific continues to systematically optimise the platform’s capabilities by refining priority disease categories and integrating local-language classifications widely spoken across the region.
  • Driving High-Level Advocacy: The team has successfully raised the project’s profile and advocated for transparency by presenting milestones at key statutory events, including the Regional Commission for Asia and the Pacific Meeting (May 2025) and the Asia-Pacific Regional Conferences in New Delhi (November 2023) and Jakarta (September 2025).

Key takeaways

1
Looking beyond official reports
Waiting for official reports can sometimes take too long. By scanning the news and the internet, we can spot early warning signs of animal diseases much faster than by relying on official channels alone.
2
Fact-checking the rumours
We do not just collect information; we actively verify it.
Find the news›Check its credibility›Confirm the facts with official authorities›Issue a formal alert
3
Regional source expansion is the future goal
Looking ahead, our biggest goal for the Asia-Pacific region is to tap into more local news and data sources in every single country and territory. More local sources mean better and faster early warnings.

Ongoing and future activities

Building upon the strong foundation established in the first year, the project is ready for continued growth and impact. Key future priorities include:

1
Enhanced early warning
Expanding the capacity of the AST Asia-Pacific to detect, analyse and respond to emerging threats.
2

Consultancy report

This consultancy report—‘Identifying barriers to notification of terrestrial and aquatic animal diseases in Asia-Pacific’—investigates the primary obstacles to immediate disease reporting across the region and proposes targeted strategies to resolve them. By providing fresh insights into the drivers of successful notification, the study strongly advocates for a strengths-based approach to implementing its recommendations, ultimately aiming to cultivate a positive, shared culture of transparency.

Gap analysis (for external distribution)

This summary report presents a gap analysis of the World Organisation for Animal Health (WOAH) epidemic intelligence activities across the Asia-Pacific region. The primary objective is to identify gaps in disease detection capacity (from official and non-official sources) and reporting performances across the region’s 43 countries and territories, to establish priority actions to enhance regional animal health threat detection capacity. The summary presented here reflects the situation in the region as of July 2024. It was developed as an initial step in designing the early threat warning support project. Key indicators will be updated in future reports.
