As Canadian children return to school and the weather cools down, the onset of autumn brings the risk of seasonal illnesses. Medical professionals emphasize that safeguarding one’s health goes beyond receiving a flu shot.
The latest federal surveillance report highlights low and stable levels of influenza, COVID-19, and respiratory syncytial virus (RSV), indicating a looming resurgence as colder weather drives people indoors. Dr. Ayisha Kurji, a pediatrician in Saskatoon, warns that the shift to indoor settings enhances the spread of illnesses, leading to increased emergency department visits and hospitalizations, particularly among children.
Dr. Matthew Miller, an immunologist at McMaster University, advises Canadians to plan for seasonal vaccinations. He points out the unusual early peak in last year’s flu season, emphasizing the importance of timely immunization to allow the body to develop protective immunity. Miller stresses that besides the flu shot recommended for all Canadians aged six months and above, families should consider a range of vaccines to stay protected.
Measles remains a concern as it continues to circulate, posing a risk of further transmission in the fall. Miller notes that post-summer travel increases the vulnerability of children returning to classrooms, potentially exposing them to various infections.
The National Advisory Committee on Immunization recommends COVID-19 vaccinations for higher-risk individuals, such as older adults and pregnant individuals with underlying medical conditions. Dr. Kurji underscores the importance of COVID-19 vaccination due to ongoing hospitalizations associated with the virus.
RSV vaccines are available for older adults and pregnant individuals to combat the severe risks posed by this virus to newborns. Studies show that these vaccines significantly reduce hospitalization rates among newborns, highlighting their effectiveness in preventing severe RSV-related illnesses.
In addition to seasonal vaccines, maintaining up-to-date routine vaccinations is crucial to prevent a resurgence of vaccine-preventable diseases like measles. Dr. Joss Reimer, Canada’s chief public health officer, emphasizes the need for consistent vaccination to protect vulnerable populations and prevent disease outbreaks.
Vaccination coverage data reveals suboptimal rates for measles, mumps, rubella, diphtheria, tetanus, and whooping cough vaccines in Canada. This has contributed to measles outbreaks across North America, with the U.S. reporting numerous cases and Canada losing its measles elimination status.
Dr. Bonnie Henry, B.C.’s provincial health officer, highlights the hospitalizations of unvaccinated children during the province’s recent measles outbreak. Dr. Kurji stresses the preventability of measles through vaccines and emphasizes the importance of complete vaccination doses for optimal protection.
The resurgence of measles underscores the necessity for vigilance and comprehensive vaccination strategies to curb the spread of preventable diseases.
