On May 1st, the Canadian Paediatric Surveillance Program (CPSP) launched 3 new multi-year studies on:

• Tick-borne diseases (excluding Lyme disease). This study will examine the epidemiology, presentation and outcomes of pediatric tick-borne diseases in Canada, helping to identify emerging trends and support greater clinical awareness of these infections.
• Severe hypernatremic dehydration in term and late preterm neonates. This study aims to better understand the factors associated with severe hypernatremic dehydration in newborns and identify opportunities for earlier recognition and prevention.
• Probiotic sepsis in infants under 2 years of age. This study will gather national data on cases of probiotic-associated sepsis in young children to help inform safer probiotic use and support improved clinical care for affected infants.

If you have seen any cases of these conditions, or any of the other conditions on our current list of studies, please report it to the CPSP.
