Two to three doses of SP has been proven to reduce the levels of placental malaria  and had a reduced risk of moderate to severe anemia. Prevention
Ways to minimise exposure to the Anopheles mosquito include:

Indoor residual sprays are one of the most utilised methods of malaria prevention by the Global Malaria Eradication Campaign. Spraying is a method used to control malaria epidemics. Nets treated with insecticide are effective at preventing mosquito contact for three years. The World Health Organization (WHO) specifically protects younger children and pregnant women in order to reduce the risk of spreading quartan fever within the population. Sulfadoxine-pyrimethamine (SP) administration to pregnant women is also a source of prevention in order to reduce the risks of maternal anaemia, low birth rate, and perinatal mortality. SP reduces the impact quartan fever may have on newborns and decrease the mortality rate. This method of prevention is known as "chemoprevention." House improvement is also a method of prevention. Traditional houses consisting of natural materials are susceptible to gaps which allow entry to Anopheles mosquitoes. House improvements including sealed windows and doors reduce the risk of coming in contact with the infected mosquitoes. Larval source management is the control and monitoring of aquatic environments in order to prevent Anopheles mosquitoes from fully developing. Mosquitoes require aquatic environments in order to fully mature and develop. Once the mosquito eggs hatch, the larva must live in the water and develop into pupa. The pupa stage then matures into a fully developed mosquito and emerges from its aquatic habitat.
Siderosis is the deposition of excess iron in body tissue. When used without qualification, it usually refers to an environmental disease of the lung, also known more specifically as pulmonary siderosis or Welders disease, which is a form of pneumoconiosis. Pulmonary siderosis was first described in 1936 from X-ray images of the lungs of arc welders.The name siderosis comes from Ancient Greek word for iron, sídēr(os), and has an -osis suffix. Signs and symptoms
Pulmonary siderosis doesnt usually cause harmful scar tissue formation within the lungs, which is why it said to be non-fibrotic condition, unlike asbestosis for example, and has also been called "benign pneumoconiosis".Mild to moderate scarring of the lungs has been found in unusual cases of pulmonary siderosis. These people have had persistent breathlessness, coughing and decreased lung function. However, people in occupations where they are exposed to iron (or rust) dust are usually also exposed to other forms of dust such as silica, which upon repeated inhalation is known to cause dangerous silicosis. Because of this, it is not known for certain whether the inhalation of pure iron or rust can cause detrimental scarring of the lungs that has been seen in some cases of pulmonary siderosis. Still, studies have shown lack of silica in tissue samples collected from people with pulmonary siderosis.
