MALARIA-P. VIVAX

Infectious Diseases

MALARIA-P. VIVAX

1. P vivax from Papua New Guinea and Indonesia should be assumed to be chloroquine-resistant; otherwise all non-falciparum species are chloroquine-sensitive and should receive chloroquine.

2. Primaquine is adjunctive medication for infections with P vivax and P ovale to eradicate hypnozoites in the liver.

3. Hypnozoites are the malarial forms responsible for relapse.

4. Remember that primaquine induces hemolytic anemia in G6PD-deficient persons, so you must screen for G6PD deficiency before prescribing it.

5. Prophylaxis in chloroquine-sensitive areas: Use chloroquine.

6. Prophylaxis in chloroquine-resistant areas: Use mefloquine or atovaquone/proguanil.
