State law mandates students are required to get two doses of the measles, mumps and rubella-or MMR-vaccine.
The increase has been driven in part by groups who, largely for religious or anti-government reasons, choose not to receive anti-measles vaccinations.
The update, from the Auckland Regional Public Health service, came at 2.00pm on Monday. A single dose of measles vaccine protects about 95 percent of children, but after two doses, nearly 100 percent are immune. A second vaccine dose is given before the start of kindergarten, between ages 4 and 6 years.
Immunisation is the best protection from measles, says Medical Officer of Health Dr Jim MIller.
For worldwide travel, infants as young as 6 months should be vaccinated against measles. It can be effective when given within 72 hours of exposure to prevent illness.
State health officials are stressing that people can not contract measles from the vaccine. The other option is that you can have your doctor do a blood draw to determine if you are immune or not, but that would take two trips to the doctors office.
High-risk individuals include those who are unvaccinated or unsure about vaccination status, pregnant women and those who are immune-compromised (have a weakened immune system due to illness and diseases like HIV, malnutrition and/or medications).
Measles, a disease caused by highly contagious virus, is characterized by such symptoms as fever, cough, runny nose, inflamed eyes and, of course, the trademark rash that spreads all across the body.
Of those, three contracted measles overseas, seven were close contacts of a case, one came from Christchurch, and one contracted measles from an unknown source, ARPHS says at the time. A small percentage of those infected can develop pneumonia, swelling of the brain or other serious symptoms.
