Coronavirus is spread primarily by droplets in the air or on surfaces. No single product can protect you absolutely. Masks are not recommended, except for infected patients and health care providers.  Hand washing and hand sanitizers are your best bet for protection. Both Purell, which contains alcohol, and Clorox wipes kill about 99% of germs. Don’t skimp—use it liberally to wipe not only hands, but surrounding surfaces. Carry individually-wrapped wipes in your purse or briefcase when away from home. Be safe and sensible.
