While your body will try very hard to make up for the disruption of homeostasis in your amount of red blood cells, without seeking treatment, the bacterium will continue to invade your red blood cells at a faster rate until there are non healthy left. Without healthy red blood cells, your body cannot deliver oxygen and carry waste and nutrients, leading to fatal results.

Common treatments: Antibiotics that kill the parasite, Anti Malarial Drugs
  • Chloroquine phosphate. Chloroquine is the preferred treatment, but in many countries, parasites are resistant to it, and the drug is not effective
  • Artemisinin-based combination therapies (ACTs). ACT is a combination of two or more drugs that work against the malaria parasite in different ways. This is usually the preferred treatment for chloroquine-resistant malaria.
