* For two flights in July 2021 involving an infectious passenger who had an extensive purulent rash, the exposure risk zone was expanded to include all passengers who had potentially used the same lavatory.

^† Passengers were considered aircraft contacts if seated within two seats of an infected traveler for flights >3 hours, or within one seat for flights ≤3 hours, in any direction.

^§ Crew either serving infected travelers or working with an infected crew member for >3 hours were classified as having an exposure.

^¶ An FPHN is a notice sent by CDC to another country through its National International Health Regulations Focal Point pursuant to Article 44 of the 2005 International Health Regulations, which calls for collaboration among countries in the detection, assessment, and response to events of potential public health significance. https://pubmed.ncbi.nlm.nih.gov/27166578
