One more Albertan has died from influenza since the last update according to the data, while newly reported cases for the last two weeks were slightly higher than the numbers seen for a month prior.
The death brings this flu season's death toll to 117.
In-hospital deaths as well as deaths in community settings reported by first responders are included in that number, while data for seasons prior to 2021-2022 only include hospital deaths.
HOSPITALIZATIONS
This season, 2,077 Albertans have required hospital care because of influenza. There were 22 new admissions since the last Alberta Health update on Mar. 16.
The province was scheduled to release its weekly data on Mar. 23 but did not, citing technical issues, instead opting to release both last week's and this week's data on Thursday.
This season has the second-highest number of hospitalizations in 14 seasons.
The Calgary zone has had the most patients requiring hospital care, with 775, followed by the Edmonton zone’s 592.
Of the 22 new admissions between March 12 and March 25, 55 per cent were 30 or older. Five of the admissions were children between the ages of one and four.
To date, 213 people have required intensive care. One new patient between the ages of 70 and 79 was admitted in this update.
The majority of ICU patients this season have also been in the Calgary zone.
CASES
Alberta reported 130 new infections on Thursday. Seventy-three of those cases were reported in the week of Mar. 12, while 57 were reported the following week. This is a departure from new case numbers staying below the 50 case mark for the four consecutive weeks prior.
According to Alberta Health data, this season has the second-highest number of cases in 14 seasons, with 9,088 infections so far. The 2017-18 flu season had the highest number of cases, with 9,115.
The Calgary zone has had the highest number of influenza cases in the province, totalling 3,069 so far.
The Edmonton zone has had the second-highest number of cases in Alberta, with 2,635.
