Definitions of Malaria Chemoprevention Strategies*

Intermittent preventive treatment in pregnancy (IPTp)	A full therapeutic course of anti-malarial medicine given to pregnant women at routine prenatal visits, regardless of whether the woman is infected with malaria
Intermittent preventive treatment in infants (IPTi)	A full therapeutic course of sulfadoxine-pyrimethamine delivered to infants in co-administration with DTP2/Penta2, DTP3/Penta3 and measles immunization, regardless of whether the infant is infected with malaria
Seasonal malaria chemoprevention (SMC)	Intermittent administration of full treatment courses of an anti-malarial medicine during the malaria season to prevent malarial illness. The objective is to maintain therapeutic concentrations of an anti-malarial drug in the blood throughout the period of greatest risk for malaria
Note: This intervention is recommended only for areas with highly seasonal malaria, where transmission occurs during a few months of the year
Mass drug administration (MDA)	Administration of anti-malarial treatment to all age groups of a defined population or every person living in a defined geographical area (except those for whom the medicine is contraindicated) at approximately the same time and often at repeated intervals
