What health officials are calling a "severe" flu season claimed another four lives across the London area last week.
The latest deaths bring the total number of people to die from flu-related complications since September to 23.
"The current influenza season is proving to be a severe one in both the Middlesex-London area and across Canada, with numerous laboratory-confirmed cases, hospitalizations, and institutional outbreaks reported," the Middlesex London Health Unit said in a statement.
In addition to the deaths, 30 people were hospitalized due to the flu last week. Laboratory tests also confirmed another 28 cases of influenza A and 37 cases of influenza B.
Cases of the B strain of the flu has been found in nearly two-thirds of reported cases and institutional outbreaks, which is higher than expected, according to the health unit.
Health officials are urging those who have not yet had their flu shot to get immunized and practice rigorous hygiene to prevent getting sick.
"Handwashing is an effective way to prevent many illnesses, including influenza," the health unit said. "Local residents should stay home when they feel sick, cover coughs and sneezes, and clean and disinfect high-touch surfaces frequently."
