In recent months, four children under the age of 10 in British Columbia have tragically lost their lives due to a severe bacterial infection contracted alongside respiratory viruses. This alarming development underscores the seriousness of a recent surge in cases of invasive group A streptococcal (iGAS) infections among pediatric patients nationwide.

Public Health Ontario recently released a report indicating a significant rise in iGAS infections, with 540 cases reported in the province between October and December, resulting in six deaths among individuals under the age of 18. Medical experts attribute this growing number to a spike in influenza and other respiratory illnesses affecting children, emphasizing the need for improved vaccination rates and other protective measures.

British Columbia health officials disclosed that the province recorded 60 cases of iGAS in individuals under the age of 20 last year, triple the number reported the previous year. Among the four children who recently passed away, two had been diagnosed with the flu while the other two had contracted the human metapneumovirus, another respiratory virus.

Caroline Quach-Thanh, a pediatric infectious diseases specialist and medical microbiologist at CHU Sainte-Justine in Montreal, explained that viral infections weaken the body's defenses, making it easier for harmful bacteria to enter. The rise in viral illnesses, therefore, increases the likelihood of superinfections with bacteria.

Normally, group A streptococcus bacteria cause mild illnesses such as strep throat or skin infections. However, in rare cases, the bacteria become invasive, entering the bloodstream or deep tissue, causing severe harm. The majority of individuals diagnosed with iGAS require hospitalization, and between 5 and 15 percent succumb to the infection. Severe strep infections can lead to conditions such as meningitis, pneumonia, toxic shock syndrome, and flesh-eating disease.

Upton Allen, head of the division of infectious diseases at Toronto's Hospital for Sick Children, suggests that increased spread of the flu, respiratory syncytial virus, and other infections may be responsible for the rise in iGAS cases. He speculates that reduced exposure to various viruses due to COVID-19 lockdowns might have resulted in diminished immunity against these infections among children.

While older individuals and those with chronic illnesses are at higher risk of contracting iGAS, medical experts note that children are experiencing the fastest rate of increase in infections. Joanne Langley, division head of infectious diseases and professor in the department of pediatrics at Dalhousie University, highlights the connection between viral illnesses and invasive strep infections, particularly mentioning the increased risk associated with chickenpox.

To protect themselves and their children, health experts urge families to be aware of the symptoms of iGAS, including fever lasting longer than five days, fever accompanied by a sandpaper-like rash, fever in infants under three months, lethargy or difficulty waking a child, or any breathing difficulties. These symptoms should prompt an immediate visit to the emergency department.

Dr. Langley emphasizes the importance of vaccination in preventing severe strep infections, particularly through influenza and chickenpox vaccines. Vaccination rates among children have declined during the pandemic due to disruptions in routine immunization programs and vaccine misinformation. It is crucial for families to understand the linkage between viral illnesses and iGAS infections and to take steps to protect themselves by ensuring up-to-date vaccinations.

Canada must prioritize efforts to improve vaccination rates and disseminate accurate information to the public. While there haven't been significant outbreaks of measles or chickenpox in the country, the high prevalence of viruses such as the flu raises concerns among experts. Vaccination remains the most effective tool in preventing invasive group A strep infections, and it is imperative that parents stay informed and ensure their children receive recommended childhood vaccinations.

As the battle against the ongoing pandemic continues, health authorities and communities must work together to safeguard the health of children and protect them from the serious consequences of invasive bacterial infections.
