The swine flu outbreak that has alarmed the world for a week now appears less ominous, with the virus showing little staying power in the hardest-hit cities and scientists suggesting it lacks the genetic fortitude of past killer bugs.

President Barack Obama even voiced hope Friday that it may turn out to be no more harmful than the average seasonal flu.

In New York City, which has the most confirmed swine flu cases in the U.S. with 49, swine flu has not spread far beyond cases linked to one Catholic school. In Mexico, the epicenter of the outbreak, very few relatives of flu victims seem to have caught it.

A flu expert said he sees no reason to believe the virus is particularly lethal. And a federal scientist said the germ's genetic makeup lacks some traits seen in the deadly 1918 flu pandemic strain and the more recent killer bird flu.

Still, it was too soon to be certain what the swine flu virus will do. Experts say the only wise course is to prepare for the worst. But in a world that's been rattled by the specter of a global pandemic, glimmers of hope were more than welcome Friday.

"It may turn out that H1N1 runs its course like ordinary flus, in which case we will have prepared and we won't need all these preparations," Obama said, using the flu's scientific name.

The president stressed the government was still taking the virus very seriously, adding that even if this round turns out to be mild, the bug could return in a deadlier form during the next flu season.

New York officials said after a week of monitoring the disease that the city's outbreak gives little sign of spreading beyond a few pockets or getting more dangerous.

All but two of the city's confirmed cases so far involve people associated with the high school where the local outbreak began and where several students had recently returned from Mexico.

More than 1,000 students, parents and faculty there reported flu symptoms over just a few days last month. But since then, only a handful of new infections have been reported — only eight students since last Sunday.
