INFECTIOUS DISEASES No RSV, Please Each year, 10,000 U.S. infants die of lower-respiratory infections - more than half of them caused by a microbe with the forbidding name of "respiratory syncytial virus." Researchers have now devised a new vaccine against...
Most adults carry telltale antibody showing that they have been infected with RSV at some time. The virus probably caused what seemed to be only a bad cold, and since the mild infection left no permanent damage, it was for gotten. But to infants under six months old, RSV is a far more serious threat...
...under-six-months baby, suggested Dr. Chanock, still has little or no immunoglobulin A to fight off RSV. So the virus gets to his bronchioles and lungs. There, it wreaks havoc by causing 50 or more cells to merge into giant combines. Oxygen exchange is so impaired that the baby has asthma-like spasms. To make matters worse, said Dr. Chanock, the G antibody circulating in the blood just below the lungs' surface actually combines with virus particles to form more damaging complexes...
...Health Service reports. The 1967 record was marred by two delayed deaths of Americans from dog bites received overseas, one in Guinea, one in Egypt. Still, there is no reason for relaxing and forgetting about rabies. Because wild animals, especially foxes and skunks, are still a reservoir of rabies virus, PHS urges continued vaccination of dogs...
Since the smallpox virus has no natural reservoir except in man, the disease can be wiped out from a large region, as it has been in North America and most of Europe, once the cycle of infection is broken by making 85% or more of the population immune. Until now, the cycle of infection has been spinning virtually unchecked in West Africa, killing 25% of the virus' victims and hideously disfiguring or blinding as many more. Measles, which carried a death rate of less than one-tenth of 1% in the U.S. even before vaccinations began, kills from...
