SUDBURY -- One of the newest COVID-19 cases reported by Porcupine Health Unit (PHU) Thursday has been removed from the area's case count.

"While completing the case investigation regarding the COVID-19 case reported as Case #78 from the area of Area of Kapuskasing, Opasatika, Val Rita-Harty, Moonbeam, Fauquier-Strickland, it was determined that this individual no longer resides within the Porcupine Health Unit (PHU) area and as such will be removed from the health unit’s case table and count," said the agency in a news release Friday morning.

Health units are only responsible for tracking infections in residents that live within the service area.

Since COVID-19 cases are reported to health units based on postal codes associated with the person's health card, this error can happen if that person has not changed their permanent address with the Ministry of Health.

"It was determined that this client had not been in the PHU area and that there was no exposure to anyone living in the community," said Nicole Ethier, health and well-being coordinator at PHU, in an email to CTV News.

No information has been provided on where the case was transferred.
