Measles is 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 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 4 days before to 4 days after the appearance of the rash.
Doctors with patients suspected of having measles are asked to:
- Notify urgently any patient with suspected measles to the CDCB on 1300 232 272 (24 hours/7 days). Do not wait for laboratory confirmation.
- Arrange urgent laboratory testing through SA Pathology. Take throat swabs in viral transport medium for measles PCR (preferred specimen) and urine for measles PCR (yellow top container).
- Isolate suspected and confirmed measles cases and exclude from child-care/ school/ workplace for at least 4 days after rash appearance.
- Ensure all household and other contacts are protected against measles as indicated in the Australian Immunisation Handbook.
- Minimise transmission of measles:
- Examine patients suspected of having measles in their own homes wherever possible.
- Ensure the patient is only seen by practice staff who have confirmed immunity to measles.
- Ensure suspected cases do not use the waiting room, and conduct the consultation in a room that can be left vacant for at least 30 minutes afterwards.
- Treat all people who attend the rooms within 30 minutes of the infectious patient as contacts.
- Two doses of a measles containing vaccine are highly effective at preventing measles. Offer measles vaccine (unless contraindicated, for example in pregnant women or immunosuppression) to all potentially susceptible persons who attend your practice.
- Measles vaccine should be considered in susceptible persons prior to overseas travel.
- Many people born in the late 1960s to mid-1980s may have only received one measles vaccine.
