Taiwan has reported a cluster of COVID-19 among pilots that began with an infected pilot from New Zealand.
After contact tracing, authorities believe the New Zealander failed to wear a mask after developing a cough, infecting two co-pilots, including a Taiwanese national. This Taiwanese national then infected her two co-pilots during another flight on December 18.
The New Zealand pilot at the source of the cluster is known to have traveled in northern Taiwan between December 8 to 11 while still infected, after completing the three days of home quarantine required for flight crew.
