APHIS Added Thailand to the List of Regions Considered Affected with African Horse Sickness

Contact: APHIS Press Box

Summary: The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) is advising the public that we have added Thailand to the list of regions APHIS considers to be affected with African horse sickness (AHS). We have taken this action because of confirmation of AHS in Thailand.

AHS is a fatal viral equine disease that is not known to exist in the United States. On March 27, 2020, the veterinary authorities of Thailand reported to the World Organization for Animal Health (OIE) the occurrence of AHS in that country.
In response to that report, on March 31, 2020, APHIS added Thailand to the list of regions where AHS exists. On that same date, APHIS issued an import alert notifying stakeholders that effective March 27, 2020, APHIS imposed restrictions on importation of equine and equine-derived commodities from Thailand due to AHS. This notice serves as an official record and public notification of that action.

A list of regions where AHS exists or is reasonably believed to exist is maintained on the APHIS website at:
