...that diagnosis constantly becomes more refined. Dramatic advances in laboratory technology, like the use of radioactive substances, have helped doctors better understand disease processes. Also, physicians are more alert in reporting both established and unusual illnesses to their colleagues. Some apparently new diseases existed in the past, notes Epidemiologist Michael Gregg of the Center for Disease Control in Atlanta, the nation's primary illness-monitoring station. But Gregg adds, "There may also be an essentially evolutionary environmental change. Something that is going to bring the host, the agent and the environment together in a different way from before, creating...
...team of researchers led by Epidemiologist Wolf Szmuness of the New York Blood Center has concluded a large-scale and successful test of a hepatitis B vaccine. The test involved 1,083 homosexuals, who are at particularly high risk of developing hepatitis B because of their sexual practices. Half the men received the vaccine, the rest a placebo. The men were given three injections in six months. Only eleven cases of hepatitis B occurred among the vaccinated men, compared with 60 in the control group...
...Japan alone. It has also been observed in other countries, though with a much lower incidence. In the U.S., the first cases were detected during the mid-'70s; so far only about 650 cases have been reported to the Center for Disease Control in Atlanta. But C.D.C. Epidemiologist David Bell points out that many doctors may still be unfamiliar with the disease...
...hunt, in the search for solutions. Problem: a small tribe in New Guinea, the Fore, was threatened with extinction. For unknown reasons, most of its women were being attacked by a nerve disease that began in giggles and ended in death. Dr. D. Carleton Gajdusek, an American epidemiologist, arrived in 1957 and investigated. He gave the victims every medicine on the shelves. He checked the water in the streams, the soil, even the ashes in the cooking fires. Finally, after months of inquiry, he discovered that when someone died, the Fore buried the corpse, then, as a way of preserving...
...goes a popular adage. It may be wrong. Though the obese definitely run greater risks of hypertension, heart attacks, diabetes and other ills, the very thin are not necessarily any healthier. Studying data collected on 5,209 men and women during a 24-year study, National Institutes of Health Epidemiologist Paul Sorlie and his colleagues confirmed that the obese had higher death rates than those of average weight, but they were surprised by similar high mortality rates for the underweight. The finding could not be explained by such factors as the amount of smoking or undiagnosed illness. These results, Sorlie...
