Migration of Parasites as the Cause of Anemia in Æstivo-autumnal Malarial Infections

The anemia in malarial infections is explained by the fact that each parasite destroys several red corpuscles. Reduction of hemoglobin out of proportion to the loss of red corpuscles is explained by the fact that there is always a partial loss of hemoglobin in certain of the surviving corpuscles due to parasitic action. Migration of parasites occurs in all aestivo-autumnal infections. If one wishes to observe, migrations, it will save time to study the heavy infections. Free parasites have been frequently noted by many observers, who have failed to interpret properly their presence in the blood.
