For what reason is Chloroquine not used in certain areas?

  1. Resistance issues with P. vivax and P. falciparum

  2. Side effects including nausea

  3. G6PD deficiency

  4. Underlying psychiatric conditions

The correct answer is: Resistance issues with P. vivax and P. falciparum

Chloroquine is not used in certain areas due to resistance issues with Plasmodium vivax and Plasmodium falciparum. Resistance to chloroquine has developed in many regions around the world, making it ineffective for treating these types of malaria. This resistance has led to the need for alternative antimalarial medications in areas where chloroquine is no longer effective.
