Article 9

National competent authorities or the Commission shall notify an alert in the EWRS where the emergence or development of a serious cross-border threat to health fulfils the following criteria: it is unusual or unexpected for the given place and time, or it causes or may cause significant morbidity or mortality in humans, or it grows rapidly or may grow rapidly in scale, or it exceeds or may exceed national response capacity; and it affects or may affect more than one Member State; and it requires or may require a coordinated response at Union level. Where the national competent authorities notify the WHO of events that may constitute public health emergencies of international concern in accordance with Article 6 of the IHR, they shall at the latest simultaneously notify an alert in the EWRS, provided that the threat concerned falls within those referred to in Article 2(1) of this Decision. When notifying an alert, the national competent authorities and the Commission shall promptly communicate through the EWRS any available relevant information in their possession that may be useful for coordinating the response such as: the type and origin of the agent; the date and place of the incident or outbreak; means of transmission or dissemination; toxicological data; detection and confirmation methods; public health risks; public health measures implemented or intended to be taken at national level; measures other than public health measures; personal data necessary for the purpose of contact tracing in accordance with Article 16; any other information relevant to the serious cross-border threat to health in question. The Commission shall make available to the national competent authorities through the EWRS any information that may be useful for coordinating the response referred to in Article 11, including information related to serious cross-border threats to health and public health measures related to serious cross-border threats to health transmitted through rapid alert and information systems established under other provisions of Union law or the Euratom Treaty.
