...high of 160). A total of 213 cases was reported; of those, only six were of the "benign tertian" or vivax type. All other cases were caused by the far more virulent parasite, Plasmodium falciparum, which sets off violent fevers and may make a fatal attack on the brain, spleen or other organs...
...Viet Cong terrorists began to take aim at the malaria fighters; since then, at least twelve have been killed and 58 are missing. Upland malaria is the more dangerous variety. On the coastal plains, three out of four cases are of the "benign tertian" variety caused by the parasite Plasmodium vivax, and only one case out of four is "malignant tertian," caused by Plasmodium falciparum. In the hills, the proportions are reversed. Falciparum malaria usually does not last as long as the vivax form-only weeks or months, instead of years-but it is far more disabling while it lasts...

Swamp drainage and screening of buildings have been added to the force since 1898, when it was shown that malaria parasites (tiny protozoa of the genus Plasmodium) spend part of their life cycle in female Anopheles mosquitoes. The mosquito picks up the parasites from infected humans, nurtures them and injects them into fresh victims. The parasites run through the bloodstream of their victim, causing periodic fevers at the peak of their reproductive cycle; many lodge in the spleen, causing local pain...

He found a mental patient who was about to be given malaria anyway for treatment of general paralysis. The patient and his wife agreed that doctors could take out a small piece of his liver by a minor operation, seven days after he had been bitten by infected mosquitoes. At 5 o'clock one morning Dr. Shortt got the sliver of liver, rushed to his laboratory and worked...
