The OIE has established a warning system allowing member countries to take rapid action should need arise. Within 24 hours of the occurrence of the outbreak of a List A disease, or any other infectious disease that could have serious repercussions on public health or on the economy of animal production, the affected country reports the incident to the OIE Central Bureau. Central Bureau immediately sends a summary of the warning message by e-mail to the member countries. The complete message is published weekly in Disease Information, available online or by post.
