MIDDLESEX CENTRE, ONT. -- The Middlesex-London Health Unit is reporting five new cases of COVID-19 on Tuesday, all in the City of London, but no new deaths.

Two seniors’ facilities continue to deal with ongoing outbreaks.

There was one new case reported by Southwestern Public Health on Tuesday.

That brings the totals for Elgin and Oxford counties to 81 cases, with 70 resolved and four deaths.
