FREDERICTON (GNB) – Public Health has declared an end to the measles outbreak in the Sussex region.

“Although this outbreak has ended, it is a clear reminder of how quickly diseases like measles can arrive in our communities,” said Dr. Kimberley Barker, regional medical officer of health. “Immunization remains our strongest defence against vaccine-preventable diseases like measles. I encourage all New Brunswickers to remain vigilant and up to date with their vaccinations.”

The outbreak, which was declared July 14, spread to 15 people. The last case was confirmed on July 19.

During the outbreak, health officials identified and managed cases and contacts, conducted surveillance, provided advice for anyone exposed to measles, and urged people to ensure their vaccinations were up to date. Public Health hosted vaccine clinics in the region, and vaccines were available in pharmacies for people aged 18 and older.

“I’m deeply grateful to the dedicated Public Health team and our health system partners for their work in containing this outbreak,” said Barker. “I would also like to thank those living in the region for their adherence to the guidance provided by Public Health. It was through this collective effort – working together, across sectors and communities – that we were able to quickly bring this outbreak to an end.”

Most people are protected from measles infection from two doses of vaccine. In New Brunswick, the measles-containing vaccine is part of the routine publicly funded schedule. It is available for those born in 1970 or later who have not received two doses.

The measles virus is transmitted through the air or by direct contact with an infected person. Measles can be more severe in adults and infants and can lead to complications. All residents are urged to consider vaccination as the best way to protect themselves and their families against measles and other vaccine-preventable diseases.
