Animal health epidemic intelligence report - Asia and the Pacific
Incoporating official WAHIS data and active search intelligence
Period covered and objective
Q3 2025: 01/07/2025– 30/09/2025
To improve early detection and preparedness, this report syntheses official information collected through the WOAH WAHIS reporting system and non-official information gathered by the WOAH Active Search Asia-Pacific team during the period of interest.
The primary objective of this report is to provide a quarterly update on the animal disease situation in the Asia–Pacific region. It draws on a combination of official data from WAHIS and non-official information collected through WOAH’s epidemic intelligence initiative.
Summary of key points
Summary of WAHIS official data
Exceptional events (alert messages sent by WOAH Members): during Q3 2025, 23 exceptional animal disease events were reported. The majority were recurrences of a listed disease (16), with others related to first occurrences in a zone (4), strain recurrences (2), or unusual/new host (1).
Top reported diseases: a total of 156 outbreaks for 15 diseases were reported. Rabies was the most frequent, with 78 outbreaks, followed by HPAI in poultry (28) and classical swine fever (23).
Reporting countries/territories: outbreaks were reported by 17 countries/territories. The most frequent reporters were: Thailand (63 outbreaks) Japan (23), Cambodia and Timor-Leste (22 each).
Summary of epidemic intelligence (active search) findings
News item (information collected through the EIOS system) analysis: during Q3 2025, 7,171 news items were reviewed. Of these, 189 were identified as relevant to WOAH-listed or emerging diseases.
Top news topics: three diseases accounted for 64% of all relevant news items: ASF (39%), HPAI (15%), Lumpy skin disease (10%)
News items by location: News items were detected in 19 countries/territories. The reporting was highly concentrated: a single country/territory accounted for 32% of all news, while the top three countries/territories made up 73% of the total.
Official reports from active search: following 7 communications sent to countries/territories, 4 official reports were received as a direct result of these active search efforts.
Official information Q3 2025
This section analyses the official information reported during Q3 2025, through the WAHIS system categorising reports by disease and affected country/territory.
During Q3 2025, a total of 23 exceptional events were reported to WOAH (events that started in the period Q3 2025). Sixteen of these were related to the recurrence of a listed disease, 4 to the first occurrence of a disease in a zone, 2 to the recurrence of a strain, and 1 to the detection of a disease in an unusual host. HPAI was by far the most reported disease (9 IN), followed by FMD (3), and ASF (2).
One hundred and fifty-six outbreaks were reported (through immediate notification and follow – up reports) for 15 diseases.
The number and percentage of outbreaks reported in Asia-Pacific by disease in Q3 2025 is reported in the table below.
Exceptional event outbreaks were reported through immediate notifications and follow-up reports by 17 countries/territories in the region. The ones for which reporting was most frequent were Thailand, followed by Japan, Cambodia and Timor-Leste. Outbreaks distribution by disease is displayed in the map below
