medical experts

(CBS)  After the Evening News, CBS News medical correspondents Dr. Jon LaPook and Dr. Jennifer Ashton sat down with flu expert Dr. Peter Gross to answer viewers questions about swine flu.

Q: Should I buy Tamiflu?

A: "The national stockpile consists of doses of Tamiflu for one-quarter of the U.S. Population," said Ashton. "Ideal use of Tamiflu is on the advice of a physician. You first want to be diagnosed. It's not for someone with a cold coming on."

LaPook said there is plenty of Tamiflu for the people who need it unless there is a run on it. "Doctors should not be giving Tamiflu because they are being pressured by their patients," he said.

Q: What are symptoms of swine flu?

A: LaPook said symptoms include fever, aches and pains, cough, headache, runny nose, sore throat, and can include gastro-intestinal symptoms like nausea, vomiting and diarrhea.

"This is beyond the cold," Ashton said. "You feel like you want to die. These are severe symptoms. It's not something where people are going to work and thinking, 'I'm not feeling my best today.' It's severe and not subtle."

Gross said that one key thing that was being emphasized during this outbreak as opposed to other epidemics is the need to stay home if you are feeling ill, as well as keeping sick children out of school.
