SEXUALLY TRANSMITTED DISEASES The lessons of the '70s and '80s seem to have been lost on this generation of sexually active young adults. The Centers for Disease Control and Prevention (CDC) reported a rise in cases of early-stage syphilis last year (up 29% from 2000, largely among gay men) and chlamydia (up nearly 6% since 2003). By contrast, rates of gonorrhea dipped to their lowest level since 1941, when record-keeping began...
...Organization. Recently, the virus spread to birds in eastern Europe. Avian influenza A is currently only transmitted to humans via contact with birds. However, an influenza pandemic could begin if the virus mutated, enabling it to spread from person to person easily, according to the Centers for Disease Control (CDC). Yesterday President Bush announced a $7.1 billion plan to stockpile vaccine doses and prepare the nation for a possible outbreak. (See story, page 2.) Harvard University Health Services (UHS) Director David S. Rosenthal said the University has already begun to plan its response. “We have an incident...
...Number of hepatitis A infections that could be prevented each year in the U.S. with child vaccinations, according to a CDC advisory panel that unanimously recommended routine vaccination of all 1- and 2-year-olds...
...quantifying its benefits is also tricky. In the 1950s, advocates claimed a 60% drop in cavities. But with the spread of fluoride toothpastes and the use of plastic sealants by dentists, decay has plummeted even in regions where there is little or no fluoride in the water. A 2001 CDC study found that by the time they were 12, kids in fluoridated communities averaged only 1.4 fewer cavities than those in non-fluoridated areas. And even in fluoridated cities, severe decay remains rampant among the poor--partly because some 85% of dentists, according to state surveys, reject Medicaid patients. Still...
...parsing risks, Bellingham is also weighing an undisputed side effect of ingestion. The CDC recently announced that 32% of American children now have some form of dental fluorosis, a white or brown mottling of the teeth. U.S. health officials see it as a cosmetic issue, largely caused by ill-advised swallowing of toothpaste, while fluoride critics say it shows that children are accumulating too much fluoride overall. The World Health Organization sets a fluoride-safety standard of 1.5 p.p.m.--well below the EPA's 4-p.p.m. rule--partly to prevent enamel fluorosis. And in Western Europe, where the drop...
