Svínaflensan talin mild
Samkvæmt þessari frétt gera vísindamenn ráð fyrir því að svínaflensan verði tiltölulega mild, og hugsanlegt sé að hún valdi minna tjóni en hefðbundnir inflúensufaraldrar gera árlega, þó með þeim hefðbundna fyrirvara að flensan geti hugsanlega stökkbreyst á einhverjum tímapunkti.
Líklegt sé þó að hún verði eitthvað alvarlegri en hefðbundin flensa, en ekkert í líkingu við til að mynda spænsku veikina. Kvikindið er sumsé fjarri því hættulaust, en það er enn sem komið er engin ástæða til að fara í sérstakan hamfaragír. Þetta virðust snúast um upplifun og athygli frekar en raunveruleg hætta sé á ferðum. Talið um heimsfaraldur virðist ekki snúast um neitt sem við vitum fyrir víst, heldur vegna fjölmiðlaathygli.
“Let’s not lose track of the fact that the normal seasonal influenza is a huge public health problem that kills tens of thousands of people in the U.S. alone and hundreds of thousands around the world,” said Dr. Christopher Olsen, a molecular virologist who studies swine flu at the University of Wisconsin School of Veterinary Medicine in Madison.
“Any time someone dies, it’s heartbreaking for their families and friends,” Olsen said. “But we do need to keep this in perspective.”…
“This virus doesn’t have anywhere near the capacity to kill like the 1918 virus,” which claimed an estimated 50 million victims worldwide, said Richard Webby, a leading influenza virologist at St. Jude Children’s Research Hospital in Memphis, Tenn.

“There are certain characteristics, molecular signatures, which this virus lacks,” said Peter Palese, a microbiologist and influenza expert at Mt. Sinai Medical Center in New York. In particular, the swine flu lacks an amino acid that appears to increase the number of virus particles in the lungs and make the disease more deadly.

“We expect to see more cases, more hospitalizations, and, unfortunately, we are likely to see more deaths from the outbreak,” Health and Human Services Secretary Kathleen Sebelius told reporters Wednesday on her first day at work. But certainly nothing that would dwarf a typical flu season. In the U.S., between 5% and 20% of the population becomes ill and 36,000 people die — a mortality rate of between 0.24% and 0.96%.…
And a pandemic doesn’t necessarily have a high fatality rate. Even in Mexico, the fatalities may simply reflect that hundreds of thousands of people have been infected. Since the symptoms of swine flu are identical to those of a normal flu, there’s no way to know how many cases have evaded government health officials, St. Jude’s Webby said.
