...responded to their efforts by restricting the use of DDT. Several states have gone even further, banning the chemical completely. But DDT still has its defenders. The World Health Organization, admittedly more concerned with public health than conservation, has warned that a ban on DDT spraying could doom worldwide malaria-eradication efforts, which in the past 25 years have freed more than 1 billion people from the debilitating disease...
...sounding the alarm, which should give pause to even the most ardent environmentalists, WHO pointed to the experience of Ceylon, located off the southern tip of India in a tropical climate ideal for the breeding of the malaria-carrying Anopheles mosquito. There, a concentrated campaign of DDT spraying cut the incidence of malaria from 2.8 million cases in 1946 to only 110 cases in 1961. But after Ceylonese authorities, considering the battle won, dropped the spraying program, the disease returned with a vengeance. During 1968 and 1969, it afflicted 2.5 million people...
...most people. The xenophobic Said permitted few foreigners in and fewer Omanis out, but an estimated 200,000 subjects managed to flee during the past ten years. Cannons sounded curfew after sundown. With only three schools in the entire sultanate, the population was more than 90% illiterate. Malnutrition, malaria, tuberculosis, trachoma and leprosy were endemic, but there was only one hospital, staffed by American missionaries. Terrified of assassination, the Sultan abandoned his capital of Muscat and barricaded himself farther down the coast in a crumbling palace in the town of Salala. There he stacked machine guns in every room...
Sickle-cell anemia is a truly discriminating disease: 99% of its U.S. victims are black. The result of a genetic mutation that occurred in Africa centuries ago, it reduces susceptibility to malaria in the 8% to 10% of U.S. Negroes who carry it. But in those (about 1%) actually harmed by it, periodic crises distort the normally spherical red blood cells into crescent-like ("sickle") structures, which then block the narrow capillaries. This deprives nearby tissues of needed oxygen and causes severe pain. The disease kills at least half its victims before the age of 20; only a handful live...
HEALTH: More hits. The World Health Organization's global disease-eradication programs have made considerable progress in the control of malaria and other diseases...
