In the midst of the northern hemisphere’s chilling winter, Canada is witnessing a late yet robust commencement of its annual respiratory virus season. Recent observations indicate that the country is witnessing an escalated influx of influenza cases, with hospital admissions surpassing those from the previous decade. Health professionals such as Dr. Karim Ali, Director of Infection Prevention and Control in Niagara Health, Ontario, highlight this year’s unprecedented influenza prevalence.
Simultaneously, Quebec sees around one-third of its recent flu tests returning positive, a fact that emphasizes the intensity of this flu season. Historically, between 10 to 20 percent of children admitted for influenza needed intensive care and this season’s statistics are pending investigations. Despite the rising concern, health professionals remind families that it’s not too late for vaccination.
Influenza vaccinations play a crucial role in preventing infections and subsequent hospitalizations, particularly amongst high-risk groups. These include the very young, the elderly, pregnant women, cancer patients on chemotherapy, and those with underlying health conditions such as asthma and heart diseases. Despite national vaccination targets aiming at 80 percent, current vaccination coverage in Canada rests below 50 percent.
As the flu season traditionally extends until April, professionals believe that delayed peaks resulting in waning immunity from vaccines administered in fall might explain the high number of hospital admissions in the current season. Apart from vaccinations, adopting preventive measures such as avoiding visits to sick family members and considering antiviral medications at the infection’s onset can help mitigate the disease’s impact. The World Health Organization ensures careful selection of the influenza vaccine’s composition at its upcoming meet in London, considering the concurrent circulation of two Influenza A subtypes, H1 and H3.
This article concludes with a reminder for the public to play an active part in infection prevention and control during these demanding times.
