Measles is a highly contagious viral infection transmitted via respiratory aerosols that remain a risk to others for up to two hours after the person has left the area. The incubation period is about 10 days (range seven to 18 days) to the onset of prodromal symptoms and about 14 days to the appearance of the rash. 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 five days before the appearance of the rash to four days after the appearance of the rash.
- Two doses of measles containing vaccine are highly effective at preventing measles.
- SA Health is advising all people who are not fully vaccinated to visit their GP or local council for measles vaccination.
- Offer measles vaccination (unless contraindicated) as part of appropriate medical management to all susceptible people over nine months of age who are born after or during 1966 who attend your practice for any reason.
- Consider measles vaccination in susceptible people prior to overseas travel.
- Measles vaccine (MMR) is provided free for people born after or during 1966 who have not already received two doses of measles vaccine.
Suspected measles cases
Notify urgently any patient suspected to have measles to the CDCB on 1300 232 272 (24 hours/7 days).
- Arrange urgent laboratory testing through IMVS, including a throat swab in viral transport medium for measles PCR (preferred specimen), urine for measles PCR (yellow top container) and blood (clotted serum tube) for measles-specific IgM and IgG.
- Isolate suspected and confirmed measles cases and exclude from child-care/ school/ workplace for at least four days after rash appearance.
- Ensure that all household and other contacts are protected against measles as indicated in the Australian Immunisation Handbook 10th edition pages 280-281.
- Minimise transmission of measles in the surgery:
- Examine patients suspected of having measles in their own homes wherever possible.
- Have the suspected case avoid using the waiting room and conduct the consultation in a room that can be left vacant for at least two hours afterwards.
- Treat all people who attend the rooms within two hours of the infectious patient as contacts.
