The H1N1 flu is cause for concern and caution, but not panic, said a New York physician.
This particular strain, while very contagious, isn't very lethal, said Dr. Margaret Lewin, the medical director of Cinergy Health. She is board-certified in internal medicine, hematology and medical oncology.
Seasonal flu causes 30,000 deaths a year. Last year, 600 people died from H1N1 influenza and almost all had compromised immune systems, Lewin said.
