...trade-off between the ability to cause severe death and transmissibility," says Steven Kleiboeker, a virologist and the chief scientific officer for ViraCor Laboratories. The A/H1N1 virus may be attenuating itself as it spreads from person to person, becoming easier to catch but less dangerous. (Read "CDC Readies Swine-Flu Vaccine...
...looking at. Experts predict we'll eventually begin to see fewer new cases in Mexico, as lab results separate real swine-flu infections from normal respiratory disease. Meanwhile, the anticipation of more cases and deaths in the U.S. has already been begun to be borne out. As the CDC's Besser himself has pointed out, swine flu is going to be a marathon, not a sprint - and we've only just gotten started...
...Richard Besser, acting director of the Centers for Disease Control and Prevention (CDC), said the agency has begun cultivating the seed stock of virus needed for a swine flu vaccine. (The current seasonal flu vaccine would not be effective against the swine flu.) "We're moving forward aggressively so that if a decision is made that we need to rev up production to make that vaccine, we would be ready to do so," he said. (See pictures of thermal scanners hunting for swine...
...even if the CDC's seed stock of virus were to be released to vaccine makers today, it would take the companies anywhere from four to six months before the first inoculation could be ready for public use. That's because flu-vaccine production - whether for swine or seasonal flu - is time-consuming and laborious, requiring vaccine makers to grow millions of copies of the flu virus in chicken eggs, then purify those bugs into a ready-to-inject formula safe for patients. "We are moving things around to accommodate this and getting our raw materials ready and having...
...clearly too late for that now - the swine flu virus has jumped across borders, and both the WHO and CDC have acknowledged that containment is no longer an option. So, while raising the alert level, the WHO also recommended that countries do not close borders or impose travel bans. "Restricting travel would have very little effect on stopping the movement of this virus," said Fukuda. At this point, trying to close borders would be like closing the barn door after the horse has bolted - better to focus on community-level protections like better disease surveillance and hygiene.
