Measles

SA Health has been notified of a case of measles in a 25 year old female from metropolitan Adelaide who had recently returned from south-east Asia. This case is not connected to the two cases of measles reported last week. The case was in the settings listed below whilst infectious:

  • Hallett Cove Corner Surgery, 10 Ramrod Ave, Hallett Cove from 10:30am until 11:30am on Saturday 10th September
  • Hallett Cove Chemplus, 45 Lonsdale Rd, Hallett Cove from 11:00am until 12:00 noon on Saturday 10th September.
  • Seaford Day and Night Clinic, 238 Seaford Rd, Seaford from 7:30pm until 8:30pm on Sunday 11th September, and from 2:00pm until 3:00pm on Tuesday 13th September
  • Clinpath Collection Centre, 5 Commercial Rd, Sheidow Park from 12:30pm until 13:30 pm on Monday 12th September
  • Flinders Medical Centre emergency department from 11:00pm on Tuesday 13th September until 3:30am on Wednesday 14th September.

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 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. Doctors can take throat swabs in viral transport medium for ‘measles PCR’ (preferred specimen) and urine for ‘measles PCR’ (yellow top container) at their practice.
  • 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. http://www.immunise.health.gov.au/internet/immunise/publishing.nsf/Content/Handbook10-home
  • 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 (documented history of 2 measles-containing vaccines OR measles IgG positive serology).
    • 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.

Measles vaccination

  • Two doses 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.
