Which of the following is a potential consequence of high resistance to anthelmintics?

High resistance to anthelmintics leads to an increased difficulty in treating infections. When parasites develop resistance to these agents, the standard treatments that were previously effective become less useful or ineffective. This can result in persistent infections that are harder to eradicate, requiring alternative and often more complex treatment strategies, which may include higher doses of medication, combination therapies, or the development of new anthelmintics.

In contrast, decreased incidence of infections, improved public health outcomes, and enhanced effectiveness of existing treatments would typically be linked to effective management and treatment of infections, which is undermined by the presence of resistance. Thus, understanding the impact of resistance is crucial for developing effective strategies in managing parasitic diseases.
