...swine-flu virus continued its gradual global march on Tuesday, prompting countries to strengthen efforts to stem its spread, while President Barack Obama asked Congress for $1.5 billion in supplementary spending to prepare for a possible swine-flu pandemic and installed the newly confirmed Secretary of Health and Human Services, Kathleen Sebelius, to help lead the fight against the disease. In the U.S., the caseload rose to 67 across five states - 45 of them in New York City, where health officials are investigating two new possible outbreaks at city schools - with more virus samples awaiting laboratory confirmation. New Zealand...
...after symptoms appear, antivirals Oseltamivir and Zanamivir (brand names Tamiflu and Relenza) are believed to reduce the severity and shorten the duration of the disease by current strain of swine flu. The drugs work by inhibiting an enyzme chemical helper that the flu virus uses to spread from infected human cells to healthy ones. So while not killing the virus, it helps the body fight off the disease by slowing its spread. This, in turn, may help prevent "acute respiratory distress syndrome" - the sudden worsening of flu that, along with secondary lung infections, is a main cause of death among...
...pork.) The original reservoir for flu viruses is actually wild birds, which can spread infection to domestic birds and people - as we saw with the H5N1 avian flu in Asia - and to pigs. Pigs make particularly good biological mixing bowls since they can be infected by bird-, swine- and human-flu viruses and provide a hospitable environment for the viruses to swap genes and create entirely new strains in a process called reassortment. That is what may have happened with the A/H1N1 swine-flu virus, which contains genes from bird-, pig- and human-flu viruses. "When you get a large...
...that the swine-flu virus seems well established in human beings, containment is no longer an option. The public health response must be to slow the spread, which means getting a better handle on the virus. While the difference in severity between Mexico and U.S. cases would suggest that there are different viruses affecting the two countries, researchers have genetically sequenced swine-flu viruses from both Mexican and American victims, and "we see no difference in the viruses infecting sick people and less-sick people," said Fukuda. And even if there were genetic differences, it wouldn't necessarily mean much...
...responded that there had been mixed signals from the flu epidemic in La Gloria and most who had taken ill had suffered from a familiar form of the influenza virus. He also said the government had no model of the H1N1 virus - which has features of avian, pig and human viruses - to base their studies on. "We never had this kind of epidemic in the world," he said on Monday. "This is the first time we have this kind of virus." As if to underline the point, the conference and Mexico City were rocked by tremors from a 6.0 magnitude...
