Malaria Here are two words you don't want to hear in connection with malaria: drug resistant. A pair of new studies say drug-resistant strains of the disease are indeed spreading through Southeast Asia, and that's raising fears of a "potential global health emergency." A strain that's resistant to multiple drugs has evolved and mutated into several new subgroups, the studies say. They have been found in Thailand, Cambodia, Laos and Vietnam. The strains have rendered a widely-used drug essentially ineffective, leading to treatment failures at "alarmingly high rates." The new findings come as countries and health experts struggle to fight the parasitic disease. There have been some successes -- Algeria and Argentina were declared malaria-free in May -- but in other places, cases have been rising significantly. |
