Invasive Group A streptococcal disease cases rising in region: ROW Public Health

Region of Waterloo Public Health is warning of the rise of Invasive Group A strep in the region.

Group A strep is the bacteria that causes strep throat, scarlet fever, and other skin infections. The bacteria becomes invasive when it infects more sensitive parts of the body, such as the bloodstream, spinal fluid, lungs, and the tissue surrounding muscle. Severe cases of the bacteria can cause necrotizing fasciitis, also known as “flesh-eating disease.”

Kristy Wright, the manager of infectious disease with Region of Waterloo Public Health, said they are reporting double the cases compared to the previous year.

“The number of cases has more than doubled in 2023, which is consistent with what is happening across the province, nationally, and around the world,” said Wright.

So far, one death has been recorded in 2024. The region saw seven deaths in 2023, including a young girl in March.

Symptoms of infection can include a sore throat, flu-like symptoms, like severe fever or chills, open wounds or cuts with extreme pain, as well as pain and fever with neck movement.

Parents are recommended to ensure their children are vaccinated against chicken pox, as recent infections can lead to a higher chance of developing Group A strep.

“Most cases occur in the very young, very old, and those with chronic health conditions or other risk factors,” said Wright. “I think it’s important for us to be aware and be on alert for symptoms. Especially those that are worsening.”

A recent report from Public Health Ontario found six children died from Group A strep between October and December 2023. The number of cases in the last three months has also doubled compared to the same time last year, with 540 versus 309.
