Four New Zealand schools have had to close their doors due to measles.
Recently schools in Levin have closed their doors because of measles, and earlier Waiopehu College was also closed.
Twenty-two cases of measles have been confirmed in recent weeks. Closing schools is the last resort but is an important step to stop the spread of the disease. In most cases the school opens the following day and students must prove that they have been vaccinated.
Measles is a highly infectious virus that spreads easily from person to person through the air, via breathing, coughing and sneezing. It affects both children and adults.
People with measles are infectious 5 days before and until 5 days after the rash appears.
