...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...
...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...
...fatal than other forms. But the blood parasites, which emerge from the tissues only once, can be knocked out with the old standby, quinine, or wartime atabrine, or postwar Paludrine, Camoquin and chloroquine. The same drugs have done a good job of suppressing the fever flare-ups of relapsing ("vivax") malaria, which occur when the parasites are in the blood...
While they were in the lines and exposed to Korea's vivax-carrying mosquitoes, the troops got chloroquine (after the first few, disorganized weeks). It worked fine as long as they took it regularly. Even though they were bitten, the men had few feverish attacks. But they still had malaria. When they started home, the medics went to work on them aboard troop-laden transports. This time their weapon was primaquine, developed in the laboratories of Columbia University. These returned soldiers are being checked for relapses. There have been few, according to reports available now (but still incomplete...
Early last year a team of chemists, biologists and veterinarians set out for Africa to attack the trypanosomes in their native stronghold. A single dose cured cattle infected with T. congolense and T. vivax, two worst forms of the disease. It also worked well against other forms in cattle, horses, dogs, hogs and camels. Healthy animals appear immunized against infection for as much as six months...
