While Alberta's daily COVID-19 case counts remain low compared with the peak of the third wave, a growing proportion of cases have no known source — a trend experts say is likely related to the province's reopening. In November, the number of active cases with no identified source peaked at about 85 per cent. Alberta Health said contact tracing continues "around the clock," and throughout the pandemic at least 30 per cent of cases have not been resolved. Meanwhile, Jenne said he believes improving uptake for a contact tracing app that can identify and alert anonymous contacts is the key moving forward.
