Swine flu: Surgical Mask
"Another doctor said "a respirator is designed to protect you from breathing in very small particles, which might contain viruses. This type of respirators fit tightly to the face so that most air is inhaled through the filter."
"If given N95, the probabilities of spreading the virus come down. Instead of spending Rs 10,000 for testing flu of each suspected case, a mere Rs 300 will prove more effective," he said.There are different forms of surgery mask, which are not designed to filter the virus.
