Health officials are urging Canadians to maintain healthy practices during the holiday period, as influenza is causing increased school absences and hospitalizations. Individuals over 65, under five, infants, pregnant women, and those with chronic medical conditions are particularly susceptible to severe complications from respiratory infectious diseases, according to officials.
Influenza and respiratory syncytial virus (RSV) typically surge in the fall and winter seasons, while COVID-19 remains prevalent throughout the year, as stated by the Public Health Agency of Canada. The most recent federal report on respiratory viruses, ending on November 29, revealed a 13% rise in positive influenza tests, with COVID-19 levels holding steady at 6.6%.
Provincial data indicates a rise in influenza cases in Alberta, Ontario, Quebec, New Brunswick, and other regions. Vaccination is highlighted as one of the most effective methods to safeguard against infections and severe complications, as emphasized by federal, provincial, and territorial health authorities.
Dr. Zain Chagla, an infectious diseases specialist and associate professor at McMaster University, recommends deploying flu and COVID vaccines before winter transmission intensifies for simplicity. It is also advised to consider the vulnerability of individuals to respiratory viruses, especially in long-term care facilities, as mild illnesses can potentially escalate into serious conditions if transmitted.
Furthermore, health practices like handwashing, covering coughs and sneezes, and wearing respirators and medical masks when seeking healthcare for respiratory symptoms are strongly recommended to reduce the spread of infectious diseases.
