Children and infants, as well as pregnant women and their unborn children, are at particular risk for contracting malaria. Most deaths from malaria occur in children under the age of five that live in African nations. This is partially because young children have not lived long enough to develop immunity against the disease. However, adults who do not live in areas where the disease is prevalent are also at risk of contracting severe malaria if they travel to areas where it is endemic. A variety of anti-malaria drugs are used to treat malaria in both children and adults, but some specific drugs may not be safe for children to take.
