In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s. However, if travel cannot be avoided, measures to prevent mosquito bites, along with an effective chemoprophylaxis regimen, should be implemented. Chloroquine or hydroxychloroquine are considered safe to use in all trimesters of pregnancy. Mefloquine is the agent of choice for chloroquine-resistant areas.
