Measles is a highly contagious viral infection transmitted via respiratory aerosols that remain a risk to others for up to 30 minutes after the person has left the area. The incubation period is about 10 days (range 7 to 18 days) to the onset of prodromal symptoms and about 14 days to rash appearance. The rash classically appears 4 days after prodrome onset. The illness is characterised by cough, coryza, conjunctivitis, a descending morbilliform rash, and fever present at the time of rash onset. The infectious period is from 24 hours prior to onset of the prodrome until 4 days after the onset of the rash.

Doctors are encouraged to:

• See previous public health alert for more details on responding to suspected cases and exposures.
• Notify urgently any patient with suspected measles to the CDCB on 1300 232 272 (24 hours/7 days). At the time of consultation, take a throat swab in viral transport media (preferred specimen) and urine in a yellow top container both for measles PCR; and measles serology and arrange urgent laboratory testing through SA Pathology. Isolate suspected and confirmed measles cases. Ensure suspected cases do not use the waiting room, and leave the consultation in a room vacant for at least 30 minutes after use. Ensure the patient is only seen by practice staff with immunity to measles.
• Offer post exposure prophylaxis to non-immune contacts who have been at exposure sites listed above as per Measles CDNA National Guidelines for Public Health Units.
• Offer measles vaccine (unless contraindicated, for example in pregnant women or immunosuppression) to all potentially susceptible persons who attend your practice. See Australian Immunisation Handbook.

Anyone who was at the locations and is significantly immunocompromised, or anyone who is pregnant and not fully immunised, may benefit from post-exposure prophylaxis treatment within 6 days of exposure. Speak to your doctor if you think this may apply to you.
