Despite a potential case of the swine flu in Michigan, health officials say there's no need to panic.

"I don't think people need to be overly concerned at this point in time," says Dr. Greg Holzman, chief medical executive for the Michigan Dept. of Community Health.

But they do believe the swine flu is a big deal, because they don't know much about it.

"This is a new virus strain and it's one that we haven't seen before - the swine flu," Holzman explains. "And that's what's getting us to rev up and be prepared."

Part of that preparedness is getting national, state, and local health officials on the same page of a situation they're calling 'fluid.'

Michigan has already stockpiled one million doses of Tamiflu to treat the flu, and the CDC is sending another 250,000 doses as a precaution.

"In order for them to be effective, they have to be started within 24 to 48 hours from the onset of symptoms," explains Dr. Donald Lawrenchuck, medical director for the Livingston County Health Dept. "The way they work is they prevent the virus from multiplying, from replicating."

But Tamiflu and Relenza just reduce infections.

"There is no human swine flu vaccine currently available," Lawrenchuck says. "CDC is certainly looking into that."

Meantime, state and local health officials are gearing up, should more cases of the swine flu develop.

"Do I suspect that we'll hear more cases in the United States? Yes, I do suspect that we will," says Holzman. "Whether there will be some more in Michigan, we're out out looking for it now, so there's a chance that we will probably find them, but at this point in time we don't have any more than one probable case."
