Interior Health issued a notice on Saturday confirming one case of measles had been identified in the B.C. interior.
Canterbury Medical Officer of Health, Dr Ramon Pink said measles was now "in widespread circulation" and those who weren't fully immune could be exposed to the risk of infection.
"It can now be assumed that measles is circulating widely in our community", the CDHB said in a statement.
With Canterbury health centres running out of vaccines since the start of the outbreak in late February, 3,000 MMR vaccines had been brought by Sunday (March 10) and 18,000 more are to be delivered to the region by Wednesday.
According to AZDHS, Measles spreads through the air when an infected person coughs or sneezes, and symptoms typically appear seven 12 days after exposure, but can take up to 21 days to appear in some cases.
It is the second case of mumps reported in Maricopa County so far this year.
Eventually a red blotchy rash shows up starting at the hairline and moving down the body.
New Zealand's Ministry of Health said in a statement in late February that since 2012, all cases of measles in New Zealand came from travellers bringing the disease from overseas.
Several countries have had recent measles outbreaks including the Philippines, the United States and parts of Europe.
Even though the vaccine is highly effective, globally around 110,000 people died from measles in 2017, according to the World Health Organization (WHO).
Acting Director of the Centre for Disease Control, Dr Peter Markey, said the traveler, aged in their 20s, had passed on the disease to another person. The infection begins with a fever, red eyes, cough, and runny nose. The other case was an adult who had a "common exposure" to the student. Symptoms may last five to six days.
Measles is a serious illness that is caused by a virus.
