PPE is designed to create a non-disease specific barrier to penetration of substances, solid, liquid, or airborne particles. In general, neither FDA nor the manufacturer can provide assurances that PPE will protect you against a specific disease. The data that the FDA uses for the evaluation and clearance of PPE rarely includes performance evaluation or testing against particular viruses, such as Ebola or flu. If performance data has met FDA requirements and demonstrate protection against a specific disease, the product labeling will state the claim for protection against a particular virus or bacteria.
