To the Editor: We thank Hoad and colleagues for presenting data from Australian states and territories regarding in-flight exposure to measles.1
The current cases in Queensland, Victoria and New South Wales, which have included domestic air travel,2 highlight the challenges measles still holds for Australia. Hoad et al’s report outlines the substantial public health response that such air travel events generate, despite the low likelihood of being able to use postexposure prophylaxis (PEP), measles–mumps–rubella vaccine or immunoglobulin in exposed contacts. They suggest that direct email or text messaging of passengers should be considered as an alternative to routine contact tracing, but identify that contact information is not always available to health departments.
This would require airlines to keep travel manifests for at least 14 days after a flight. Potentially exposed passengers could be directed to a health department website providing information about PEP options, use and access — for example, through their general practitioner — as well as self-monitoring for measles symptoms, and, should symptoms occur, social distancing measures.
Airlines already use social media and email to communicate with customers, and, we believe, have a duty of care to passengers that extends beyond safe arrival at their travel destination. Measles is a serious illness that leads to hospitalisation of around one-third of affected young adults in Australian outbreaks.3-6 Making airlines, as the primary holders of travellers’ details, responsible for initial contact would minimise delays and communication errors and maximise the likelihood of preventing further generations of infection in the wider community.
