A person with measles is most contagious from when symptoms start until 3 to 4 days after the rash appears.
If you have measles, or have been identified as a contact of someone with measles, the public health service will contact you to let you know what you need to do. They will support you with advice on how to keep yourself and your whānau safe during your illness.
If you have measles, you must isolate (stay at home and not go to work or school) for at least 4 days after your rash appears to avoid giving it to others.
If you have had contact with someone with measles but are not sick, you will need to isolate at home, unless you are immune to measles, for example:
- you are immunised
- you have had measles before, or
- you were born before 1 January 1969.
You can also use the 'Measles quarantine calculator' to work out how long you should stay home.
