Nova Scotia’s peak flu season, typically occurring in late December and early January, is anticipated to arrive earlier this year, according to Dr. Robert Strang. The flu usually spreads from west to east in Canada, causing Nova Scotia to lag behind other regions. Strang, Nova Scotia’s chief medical officer of health, noted a recent surge in Central Canada, raising concerns for increased infections as people gather for the Christmas holidays, coinciding with lower healthcare staffing levels.
The predominant flu strain in Canada this season appears to be influenza A (H3N2). However, the current vaccine may not be the best match for this specific strain. Despite this mismatch, Strang emphasized the importance of getting vaccinated as the vaccine still offers protection against severe disease from H3N2, as well as other strains like A (H1N1) and B.
Due to the vaccine mismatch, Strang recommended additional preventive measures such as wearing masks in crowded indoor areas, staying home when sick, practicing good hand hygiene, and using proper coughing and sneezing etiquette.
Concerns regarding the severity and increased demand on the healthcare system associated with the A (H3N2) strain, especially among children and older adults, were highlighted by Strang. Children aged six months and older are eligible for the flu vaccine, with those under nine requiring two doses for the first vaccination. Pregnant women were also urged to get vaccinated to protect themselves and their unborn child from potential complications.
In addition to flu vaccinations, Strang encouraged the public to receive COVID-19 shots. He reported a modest increase in COVID-19 cases recently, aligning with the typical fall waves in the province. Nova Scotia has introduced a free RSV vaccine program for seniors and children, which Strang promoted as another important preventive measure.
