BACKGROUND: Between January 24, 2020 and February 15, 2020, an outbreak of
COVID-19 occurred among 335 passengers on a flight from Singapore to Hangzhou in
China. This study aimed to investigate the source of the outbreak and assess the
risk of transmission of COVID-19 during the flight. METHOD: Using a standardized
questionnaire, we collected information on the travelers' demographic
characteristics and illness before, during, and after the flight. We also
collected data on factors potentially associated with COVID-19 transmission
during the flight. RESULTS: A total of 16 COVID-19 patients were diagnosed among
all passengers; the overall attack rate was 4.8%. The attack rate among
passengers who had departed from Wuhan was significantly higher than that among
those who had departed from other places. One passenger without an
epidemiological history of exposure before boarding developed COVID-19. During
the flight, he was seated near four infected passengers from Wuhan for
approximately an hour and did not wear his facemask correctly during the flight.
CONCLUSIONS: COVID-19 transmission may have occurred during the flight. However,
the majority of the cases in the flight-associated outbreak could not be
attributed to transmission on the flight but were associated with exposure to the
virus in Wuhan or to infected members in a single tour group.
