Another two Queenstown residents have tested positive to measles, as health officials continue to fight against the spread in the community.

Since August 7, there has been a total of 26 confirmed cases, many of whom work for NZSki at The Remarkables skifield.

Twenty-five people who have contracted the virus are residents, while one was a visitor from Auckland.

Southern District Health Board's medical officer of health, Susan Jack, said it is particularly important unvaccinated and vulnerable people be aware of coming into
contact with an infectious person.

"Vulnerable people include those that are pregnant, immune compromised or too young to be vaccinated,'' Dr Jack said.

"Close contact with a measles case means sharing a confined space such as a house, classroom, car or other indoor area.''

Symptoms include a sore throat, running nose, red eyes, and a blotchy rash.

People who have had direct contact with measles cases should get advice from Healthline on 0800 611 116.
