Protective measures against the coronavirus COVID-19
Countries are reminded of the purpose of the International Health Regulations to prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade. Countries implementing additional health measures which significantly interfere with international traffic are required to provide to WHO, within 48 hours of implementation, the public health rationale and relevant scientific information for the measures implemented. WHO shall share this information with other States Parties. Significant interference generally means refusal of entry or departure of international travellers, baggage, cargo, containers, conveyances, goods, and the like, or their delay, for more than 24 hours.
