Ontario health officials are reporting another record-breaking number of new COVID-19 cases as more than 18,000 infections are logged on Saturday.

Public Health Ontario, which released the data, confirmed 18,445 new cases of the novel coronavirus today, surpassing the previous record of 16,713 new COVID-19 infections reported on Friday.

Ontario's rolling seven-day average has soared to 12,495, up from 5,939 at this point last week.

The province noted on Saturday’s epidemiological report that due to changes in availability of testing, case counts are an underestimate of the true number of infections in Ontario.

Officials warned the data should be “interpreted with caution.”

The province adjusted its testing guidelines for the public this past week due to the scarcity of polymerase chain reaction (PCR) tests across the province.

PCR tests are now only be available for symptomatic high-risk individuals and those who work in the highest risk settings, as well as vulnerable populations.

Members of the general public with mild symptoms are being asked not to seek testing.

The province recorded 12 new deaths on Saturday, bringing the total death tally in the province to 10,206.

The province deemed 4,769 more cases of the disease to be resolved as of Saturday, bringing Ontario's number of recovered patients up to 652,114.

Today's report brings the total number of lab-confirmed cases in Ontario to 774,806, including deaths and recoveries.
