What is anthelmintic drug resistance in humans?

Anthelmintic resistance is a heritable loss of sensitivity of an anthelmintic in a parasite population that was in the past susceptible to the same anthelmintic.

What does anthelmintic resistance mean?

A worm is said to be resistant if it survives exposure to the standard recommended dose of the anthelmintic. Anthelmintic resistance is said to exist in a population of worms if more than 5% of the worms survive treatment.

What is the cause of anthelmintic resistance?

As documented, the reason for development of resistance to anthelmintics is a selection of resistant individuals in the worm population as a result of anthelmintic exposure.
