Measles case confirmed (updated)
Canterbury DHB is alerting the general public that they may have been exposed to measles.
A person has been confirmed as having measles and was infectious while travelling across multiple locations in the South
and North Islands between Saturday 28 December 2019 and Monday 6 January 2020.
Canterbury DHB’s Community and Public Health team has been working to identify all close contacts of this person,
determining their immunisation status and offering advice regarding what further action they should take.
Anyone who was in the following locations at the times listed should be aware that they may have been exposed and at
risk of developing measles, unless they are sure they’ve had two MMR vaccinations or are over 50 years of age. If they
are not in either of those two groups, they should isolate themselves at home until the dates listed (inclusive):
•28 December 2019 – Interislander Ferry Wellington to Picton, 8.45am – 12pm – remain isolated until 11 January 2020
•30 December 2019 – 03 January 2020 – Whare Flat Folk Music Festival (near Dunedin) – remain isolated until 17 January 2020
•30-31 December 2019 – ED at Dunedin Hospital between 8.30pm – 1am – remain isolated until 13 January 2020
•6 January 2020 – Interislander Ferry Picton to Wellington, 2.30–5.45pm – remain isolated until 20 January 2020
Dr Alistair Humphrey, Canterbury Medical Officer of Health, says immunisation is the best protection against measles.
This is especially important for children who haven’t yet had their MMR vaccinations scheduled at 15 months and 4 years.
These children are currently top priority for vaccination.
“If you are unwell and think it might be measles, stay at home and telephone your General Practice team any time of day
or night. Please don’t visit your GP team, other health provider or a hospital in person as this will spread the
illness. If it’s an emergency call 111,” says Dr Humphrey.
People are considered immune if they have received two doses of MMR vaccine, have already had measles previously, or
were born before 1969 – people born before this time will have been exposed to measles and most will therefore have had
Dr Humphrey advises that “people are infectious from five days before the onset of the rash until four days after the
rash appears, so it is possible to transmit the infection before you feel unwell. People who have been exposed and who
are not immune should remain isolated from 7 days after their first exposure to 14 days after their last exposure.”
“This means staying home from school or work and having no contact with unimmunised people. If you are not sure whether
you are immune telephone your General Practice team – they can advise you,” says Dr Humphrey.
Anyone with measles symptoms or who believes they may have been exposed, can contact their usual general practice 24/7
for additional advice. If people call their GP Team after hours, they can be put through to a nurse who can provide free
health advice and advise what to do and where to go if you need to be seen urgently.
