As acknowledged by the CDC guidance, "It is important to remember that protecting against the spread of H1N1, or any type of flu, requires a multi-level approach, and the most effective measure for protection is vaccination," said Rupp, adding that "unfortunately this debate on respirators versus masks has distracted hospitals and clinics from investing in efforts that we know will pay off such as rigorous and consistent application of basic infection control and personal hygiene practices including adherence to cough etiquette and hand hygiene, rapid identification and separation of patients with the virus, and excluding sick workers and visitors from the hospital."

"Along with scientists around the world, we will continue to research H1N1 and its transmissibility," said Rupp. "We understand the role of the CDC in providing reassurance during a period of evolving evidence, and we urge the CDC to continue to revisit its recommendations as new data becomes available."
