Three cases of measles confirmed in South Island
Three cases of measles have been confirmed in the last four days in the South Island. This is a notifiable disease and the cases have been reported in Queenstown, Wanaka and Christchurch.
At this time the common place of exposure for all three cases is Queenstown Airport, where all three are likely to have been in contact with an unknown infectious case on 21 or 22 March. This person may have had a relatively mild illness and will now be fully recovered. Any other at-risk people exposed on 21 -22 March are now at the end of their maximum incubation period and unlikely to get sick.
None of the three known cases were immunised to measles.
Southern and Canterbury DHBs are working together on this investigation and close contacts of all three cases have been identified and are being followed up.
Unimmunised people who have been exposed to any of the three cases are most likely to become ill between 10 - 20 April. People are considered immune if they have received two doses of MMR (measles, mumps, rubella) vaccine, have had a measles illness previously, or were born before 1969.
Canterbury DHB Medical
Officer of Health Dr Ramon Pink says it’s important people
with symptoms don’t visit GP rooms or after-hours clinics
but phone their family doctor/general practice team first
for advice, to limit further exposure to other
“People are infectious from five days before the onset of the rash to five days after the rash starts and should stay in isolation during this time. This means staying home from school or work and having no contact with unimmunised people,” says Dr Pink.
If people call their GP Team after-hours a nurse will answer the call and advise what to do and where to go if you need to be seen.
Measles is a highly infectious viral illness spread by
contact with respiratory secretions through coughing and
sneezing. Unimmunised people exposed to measles first
develop a respiratory type of illness with dry cough, runny
nose, temperature over 38.5 C and feel very unwell. The rash
starts on day 4 – 5 of the illness usually on the face and
moving down to the chest and arms.
The best way to protect yourself from measles is to have two MMR vaccinations. MMR is available from your family practice and is free to eligible persons.
