While I agree with the assessment of physicians and veterinarians should work together. Facts were wrong in the episode. Ticks require 3 blood meals over its life span, a blood meal at each stage larva, nymph, and adult. When a disease causing agent is ingested at an earlier stage, the tick can transmit it during the next stage, which is why ticks are a good transmitter of disease.
Tapeworms are not directly transmitted from the pet to the person, therefore a physician would not need to know the pet had tapeworms. A human is most commonly infected with tapeworms by eating undercooked meat. Please get your facts right.
