A second person has died in Alberta due to COVID-19 and 57 new cases have been identified.

Dr. Deena Hinshaw made the announcement on Tuesday during her daily update, which saw the largest jump in confirmed cases for a single day.

Hinshaw offered her condolences to the family and loved ones of the woman who died, who was in her 80's and a resident at McKenzie Towne Continuing Care Centre in Calgary.

One staff member and two other residents at the facility have also tested positive for COVID-19, while 11 other residents with symptoms are being tested. Hinshaw says the staff member who tested positive had no travel history and did not work while symptomatic. Other staff members who had contact with the residents who have tested positive will be identified and isolated.

The source of the infection at the continuing care facility remains under investigation.

"This news is extremely sad for all of us, but we are doing everything we can to limit cases of critical illness and death from this serious virus," says Hinshaw. "Tragically we know that death will occur."

Hinshaw reiterated that most people who become ill with COVID-19 will experience mild symptoms, however it can make others very sick.

"This is why we have taken the extreme measures we have and why I cannot emphasize enough the importance for all Albertans to follow all public health guidance," says Hinshaw, adding they are looking at additional measures to prevent the virus from spreading further.

"Today's report of a second death and the increasing number of affected Albertans is why these aggressive measures are in place and it's why every day we are working together to ensure that we are doing everything we can to stop the spread and keep each other safe," says Hinshaw. "Every single Albertan has a role to play."

Alberta now has 358 confirmed cases of COVID-19. 214 of those are in the Calgary Zone. 

Up to 28 of the total cases are suspected to be caused by community transmission. 19 people have been hospitalized, seven of which are receiving treatment in the ICU. Three people have made a full recovery.

Dr. Hinshaw also clarified updates to self-isolation timelines during the press conference.

Anyone sick with cough, fever, runny nose, sore throat, or shortness of breath is to stay home until they are feeling well and at least 10 days have passed since the start of symptoms. If symptoms persist for more than 10 days, you are to continue to self-isolate.

"Travelers returning from out of Canada or people who are close contacts of a confirmed case will still need to self-isolate for 14 days upon their return or last exposure, even if they are feeling well," says Hinshaw. "Should they start to experience symptoms within this time period, they must also follow the same 10-day guidance that is true for anyone that is sick."
