Preliminary reports suggest that respirators N95 - Older equipment mouth and nose filter - prevention of swine flu better surgical face masks do not seem to be open to researchers during the meeting of the Infectious Disease Society of America (IDSA).In fact, surgical face masks, which are inexpensive and easy to wear as well as could respirators N95. At least, researchers can not prove better than others. Is the latest wrinkle in a debate. continued over the protection of health care workers from the H1N1 virus, known as swine flu.
Raina MacIntyre, Ph.D., professor of epidemiology of infectious diseases and head of the University of New South Wales Faculty of Public Health and Community Medicine in Sydney, Australia, said research team did not match the resolve.
"We will analyze the same data different for the final paper," she explains.
The new analysis, researchers remove the control group of nearly 500 health care workers and other statistical adjustments made. In the different infection rates between the mask and respirator use is not statistically significant.
"[The study] will continue to show better than the N95s with half the rate of infection compared with surgical masks" MacIntyre said. "But the study is underpowered may be statistically significant when we remove the control group.
"Of course I will wear N95 respirator if exposed to infected patients," she added.
