Anticipation of more measles cases to come - after four days with no new infections

The tally remains at 17 confirmed cases - all no longer infectious, but 16 contacts are symptomatic.

Officials say we needs 42 days with no new cases, to declare the outbreak over.

Deputy Public Health Director, Harriette Carr, says because of the long incubation period, it's not unexpected to have a few days without cases.

She says people are in quarantine and it's still within 21 days of exposure event - so there's potential for more cases.
