A rare, potentially deadly parasitic disease that's endemic to Europe and Asia has been rising in Canada, underscoring the importance of strong border security.
Alveolar echinococcosis, a disease caused by the tapeworm Echinococcus multilocularis, was likely brought over to North America by dogs from Europe, according to Gizmodo. Domestic dogs and wild canines such as coyotes are the preferred carriers of this dangerous parasite, but humans could also become infected through their interactions with their pets, so dog owners should be on alert. Fortunately, scientists say it is rare for humans to contract alveolar echinococcosis.
