...generally feeling rotten: that's a typical case of the flu. But several times a century, flu viruses mutate so radically that they can trigger a pandemic--as health experts fear could happen with swine flu. Influenza may go all the way back to the dawn of medicine; a similar illness was first described by Hippocrates, in Greece in 412 B.C. In 1485, a flulike "sweating sickness" swept across Britain, leaving many dead--and treatments of the time, including the bleeding of patients, didn't help...
...Pennington, a virologist at the University of Aberdeen. Resistance occurs when a virus mutates in such a way as to render a drug ineffective. This is more likely to occur when an antiviral is widely used because resistant mutations are more likely to thrive and be passed on. A similar process has led to the widespread existence of antibiotic resistant bacteria such as MRSA. But it can also happen spontaneously: during this winter's flu season, when antivirals were not widely used, the dominant strain of influenza suddenly became resistant to Oseltamivir. Doctors are uncertain...
...similar model has already been implemented successfully in St. Petersburg, Fla. Decades ago, Nelson Poynter gave his two main media properties, the St. Petersburg Times and Congressional Quarterly, to an eponymous foundation with the directions that the papers were to be run as public trusts. Today, the St. Petersburg Times is perhaps the best newspaper from any small or moderate-sized city. In fact, just last week the paper won Pulitzer Prizes for both national reporting and feature writing...
...strain of the influenza virus found in pigs that is rarely transferable to humans. But the recent outbreak is believed to be a mutated form of the strain which has contributed to its high degree of contagiousness among humans. The flu’s symptoms are similar to the standard influenza virus—including sore throat, fever, coughing, body aches, and chills. While Harvard students may not be wearing face masks—a common practice in several international cities—school health officials are clear about how to prevent an outbreak on campus...
...analyzed differences in sleeping patterns, exposure to varying severities of violence, and degrees of worrying. The study concluded that there was a correlation between alterations in the body’s stress pathways, cortisol levels and exposure to violence. The symptoms attributed to an increased exposure to violence are similar to those experienced by patients with post-traumatic stress disorder, though Suglia said the children in the study were not clinically diagnosed with PTSD. “As a physician this kind of information is humbling because so much of what affects people’s health is outside...
