Obesity considered an underlying medical condition placing people at higher risk of H1N1-related complications?

Obesity has been known to create high risk factors in serious illnesses, but it is considered an underling medical condition when it comes to the risk factors in the H1N1 influenza. A total of 268 patients in hospitals with the H1N1 flu, during the early breakout, had their BMI's tested and calculated. About 15% of these patients were obese and 8% were considered morbid obese. There hasn't been much research done with how obesity can affect H1N1, but there are many other risk factors that put obese people under high risk factors when it comes down to the H1N1 flu. **This information came from the National Institute of Allergy and Infectious Diseases.
