During a health crisis, such as the Zika virus outbreak, the Commission works closely with the WHO (who is responsible for the protection of health at international level), and with EU governments to ensure that their response to cross-border health threats is coherent and well-coordinated, in accordance with Decision 1082/2013/EU on serious cross-border threats to health. The Decision lays down the responsibilities for risk assessment for the threats covered by its scope. As regards communicable diseases the European Centre for Disease Prevention and Control (ECDC) is in charge of providing risk assessment.
