The International Civil Aviation Organization (ICAO) issued a notice on Thursday, calling on appropriate coronavirus risk assessments within recommendations from the World Health Organization (WHO).

"We support WHO's call to all countries not to impose restrictions inconsistent with the International Health Regulations," the notice said.  "Exceeding its recommendations without having conducted an appropriate risk assessment could lead to unnecessary and negative impact, especially for the many vulnerable or isolated populations which rely so importantly on their global aviation connections."

The notice also urged all governments and airlines to keep informed of and follow the latest travel and health recommendations from WHO, reminding national governments of their obligation under the International Health Regulations (IHR) to inform the WHO of their public health rationales and justifications when implementing additional health measures that may significantly interfere with international traffic, within 48 hours of their implementation.
