...Largo of Bogart and Bacall. They hacked their own roads through the mosquito-ridden mangrove, sealed them off with padlocked gates, and even staked out a sheriffs substation with a walkie-talkie lookout to learn of patrols. But lately the police have regained the initiative...
...Organization (a branch of WHO), UNICEF and the U.S. Agency for International Development had cooperated with national governments in financing a massive extermination operation. In hundreds of yellow-painted Jeeps and trucks equipped with tanks of insecticides, crews traveled everywhere, spraying pools of stagnant water, obvious breeding areas for mosquitoes. Helmeted personnel entered millions of houses and shacks to spray the walls, on the rationale that the oily DDT residue would knock out any disease-carrying mosquito that alighted there.* The campaign succeeded so well that malaria was reduced in many countries to a minor public-health problem. Similar success...
...effort to stem the tide of new cases, health authorities are now using more of other insecticides, such as Malathion and propoxur to kill DDT-resistant mosquitoes-but the insects are already showing signs of developing resistance to the newer chemicals. Thus the most practical response now to malaria's new challenge, says Dr. Robert Kaiser, of the Center for Disease Control in Atlanta, is a return to the pre-DDT approaches: draining mosquito-breeding areas and monitoring water supplies. In addition, several drugs can be used both to prevent and to treat human malarial infections. Says Kaiser...
During the 1880s, Bunau-Varilla worked for a private French company that attempted to dig a canal through the muddy, mosquito-filled tropical jungle of Panama, then a province of Colombia. Any canal across Central America would have eliminated the 7,000-mile journey around Cape Horn for ships navigating between the Atlantic and Pacific oceans. At the time, most U.S. engineers favored a canal at sunny Nicaragua. The crossing there would have been 131 miles longer than at the 50-mile Isthmus of Panama. But almost all of the extra miles would have required no digging, since a Nicaraguan...
...those that have worn down and has even done costly root canal work on abscessed teeth. Pahle also suggested an easy remedy for animal bad breath: brush the offender's teeth daily-if he allows it. Other vets noted the growth of a more serious problem: heartworm-a mosquito-borne parasite that lodges in the heart, can reach a foot in length and blocks the oxygen supplied to the body. Eventually the dog tires after the slightest exertion. Several drugs are now available to prevent and treat this spreading canine disease...
