Swine Flu - N95 Mask..

1. There are currently no flu vaccinations that can prevent an attack by the H1N1 virus. The current stockpile was derived from the flu epidemic a few years ago caused by the H3N1 and related viruses, so they will not be effective here.

2. The two antiviral drugs approved by the FDA for treatment and prophylaxis of the 2009 H1N1 influenza virus are Tamiflu
(oseltamivir phosphate) and Relenza (zanamivir). However, health experts caution against using them routinely for several reasons: the emergence of resistant strains when used in mild flu infections, its ineffectiveness when given more than 48 hours after the onset of flu, the presence of side-effects (in particular,psychiatric disturbances, heart and lung disorders and deaths in children).

3. Should masks be used? Certainly not, the ordinary ones as they do not filter small particles that carry the culprit viruses.
You need to get the N95 respirators which block off 95% (hence the name) of small particles which carry the viruses.
These are expensive and are for single-use only.

What is N95 Mask is Made of


The masks are made of up to three layers of electrostatically charged microfibers that prevent 95 percent of particulates from penetrating them.

Inner Layer

The inner layer is usually made of a non-woven polypropylene cloth that is hypoallergenic and comfortable against the face.

Filter Layer

The filter layer---the middle one in three-layer masks---is made of a blown web of fabric that blocks 95 percent of particulates.

Outer Layer

In high-quality masks, the outer layer contains active carbon that absorbs harmful vapors.


Masks certified by the U.S. National Institute for Occupational Safety and Health are stamped "N95."
