The Public Health Agency of Canada said a total of 4,632 laboratory detections of influenza were reported, of which 97.7 percent were for influenza A viruses, predominantly A(H3N2).
There were 127 new influenza outbreaks -- 87 in long-term care facilities, nine in hospitals, one in a school and 30 in other facilities or communities. In addition, 114 new pediatric influenza-associated hospitalizations were reported, and 176 hospitalizations including 15 deaths among adults older than age 20, the report said.
The influenza-like illness treatment rate with doctors increased, but remained within the expected range for this time of year, health officials said.
Similar to previous years, adults age 65 and older were the most-affected this season, with 41.3 percent of laboratory detections to date, increased outbreaks in long-term care facilities, higher hospitalization rates and a high proportion of anti-viral prescriptions among those age 75 and older.
