A free, walk-in measles vaccination clinic will be held at the Queenstown Medical Centre over the next five days for unregistered and unvaccinated residents.
On Thursday night the Southern DHB announced one measles case had been confirmed in Queenstown on Wednesday.
Medical Officer of Health Dr Marion Poore said the Public Health team had done a "fantastic job" of tracing known contacts of the sole case and, to date, no other cases had been notified.
"We are urging urging people to ensure they are fully vaccinated with two doses of MMR [measles, mumps and rubella] vaccine, as this is the most effective way of preventing illness and preventing the spread of disease.
"This is a wake-up call for people to check their immunisation history."
Queenstown residents who had registered with the medical centre could check with their doctors to confirm their vaccination history.
However, for those who had no doctor in the resort, the clinic would provide the MMR vaccination — free for anyone born after 1969 — from today until Wednesday.
The clinic is being held at the Queenstown Medical Centre from 1pm to 5pm today, 10am to 2pm tomorrow, on Monday from 10am to 6pm, Tuesday from 8am to 12.30pm and Wednesday from 9am to noon.
Dr Poore said if people did not have a record of two MMR vaccinations, they should seek immunisation from their doctors.
Adults born before 1969, when measles was widespread, were considered immune and did not need vaccination.
Parents of small children should continue to work to the immunisation schedule, with vaccinations at 15 months and 4 years.
"If babies or children have not yet had their immunisations, parents are advised to keep them away from people who are sick."
Symptoms of the highly contagious disease were a runny nose, cough and fever for three to four days before the onset of a rash, starting on the head and neck.
A fever of over 38degC would be present at the time of the rash becoming obvious, along with a cough, or coryza, or conjunctivitis, or Kopklis spots.
Dr Poore said once they had a runny nose, a patient was contagious.
If symptoms developed, patients were advised to stay home, phone their general practice or Healthline (0800 611 116) and advise they had potentially been in contact with a confirmed measles case.
People with measles needed to remain isolated, staying at home.
"There is no specific treatment for measles, so managing the symptoms includes rest, plenty of fluids and fever cares such as cooling [and] paracetamol," Dr Poore said.
