In order to become infected the tapeworm eggs must be somehow ingested not inhaled.
“How do people get alveolar echinococcosis (AE)?
People who accidentally swallow the eggs of the Echinococcus multilocularis tapeworm are at risk for infection. People at high risk include trappers, hunters, veterinarians, or others who have contact with wild foxes, or coyotes, or their stool, or household dogs and cats that have the opportunity to eat wild rodents infected with AE.
Humans can be exposed to these eggs by “hand-to-mouth” transfer or contamination.
By directly ingesting food items contaminated with stool from foxes or coyotes. This might include grass, herbs, greens, or berries gathered from fields.
By petting or handling household dogs or cats infected with the Echinococcus multilocularis tapeworm. These pets may shed the tapeworm eggs in their stool, and their fur may be contaminated. Some dogs “scent roll” in foreign material (such as wild animal feces) and may become contaminated this way.”
