You might choose to self-isolate at home if youve been exposed, or think youve been exposed, to COVID-19. Ellen Mauro explains what to do.

Self-isolated individuals should not go to work, school, any public areas oruse public transport or taxis.

Vancouver Coastal Health issued a release on March 12 sayingthe risk to participants wasextremely low and attendees could continue to workas long as theydid not develop symptoms.

Henry reversed that advice with Monday's announcement.

Record attendance

Dr. David Ciriani, president of the Kamloops and District Dental Society, said the conference set records this year for attendance.

"Traditionally, attendance there is probably about, oh, just about 90 per cent of the dentists in the province," Ciriani said from his home, where he is now in self-isolation.

Ciriani and many of his colleagues are shutting down their offices, suspending elective proceduresand trying to find alternatives namely any dental staff who didn't attend the conference for patients who are dealing with severe pain or infection.

"The degree of dental services available across the province is going to be really curtailed," he said.

"This is uncharted territory for all of us."

Suspending services recommended

In a statement, the College of Dental Surgeons of British Columbia (CDSBC) said it recommendsall elective and non-essential dental services be suspended at once. Treatment for emergencies such as infection, acute pain and trauma can continue.

The CDSBCis asking all registrants to do a pre-treatment risk assessment with each patient, ideally by telephone, before performing any treatment. That assessment will be used to determine if there is any risk to the oral health provider, the patient or the public and if so, the patient will be referred elsewhere or the treatment postponed.

The CDSBC is also cancelling all in-person meetings and non-essential travel for staff.

Health authorities recommend self-isolation for 14 days and monitoringfor symptoms such as fever, cough and difficulty breathing.
