With rapid spread of virus, safety measure confusion is widespread among people. Should face masks be worn? If so when, how and what type of mask could provide an effective protection. A regular medical face mask is certainly not an option to go for, says Dr. William Schaffner, Infectious Disease Specialist, Vanderbilt University in Tennessee. (Source: LiveScience)
But, a specialized mask, named N95 respirator could aid in protecting people from the new coronavirus. This mask is much thicker than the regular surgical mask. But, wearing mask is not recommended for healthy individuals, as N95 respirator should be worn tightly on a person's face which is not advisable for a long time. According to Center of Disease Control (CDC), the mask could provide strong protection by filtering about 95 per cent of airborne particles. A healthy person wearing N95 for a long time would cause suffocation, thus, its ideal to use this masks on sick persons and their care takers, suggests World Health Organization.
The mask should be worn with perfect fitting, and ensure no gap is left around the nose and mouth to avoid air circulation. Also, the make sure to not touch the mask until it's on.
