Acute Flaccid Myelitis, or AFM for short.
It's a virus that starts out looking like the flu, but then takes on a different twist, with polio-like symptoms.
That includes temporary paralysis. And it affects kids, under the age of 15.
"In 2018, we have had 32 cases of sudden onset of weakness reported to us." says Dr. Catharine Dixon, a medical advisor at the Public Health Agency of Canada.
But she says that's not really a spike.
"We're not seeing an increase, but we're going to continue to monitor the situation and update as necessary."
And Health Canada is moving forward with an information campaign, both online and on social media.
The advice to parents: don't panic.
"We need to remind people that this is a very rare condition." says Dixon.
She says parents should tell their kids to cough into their sleeve, just like if they had the flu, and to wash their hands frequently.
The paralysis is temporary, too.
"For most people it does tend to go away over time, and you do tend to have a full recovery for many." says Dixon, "However, there are some individuals from the reports we've seen, that they can have lasting effects."
