It has been verified time and again that the microscopic Covid molecules can pass through any commercial or homemade mask. The entire nation would need the masks that Hazmat crews use which are not available to the general public.
As I've said many times, I believe the contagion is through touch. No matter how much a business cleans their facility, an infected person can come in right behind and leave the virus on a railing, et., and before the cleaning crew can clean that spot after, others will pick it up and touch their faces later.
I've repeated our protocol many times. But once again: After getting back in the car from grocery store or wife's or my appointments, we immediately wipe down anything we have touched or will touch in the car, including the closing handle, seatbelts, steering wheel, and ignition button. We keep pure alcohol in the glove box and both carry disinfectants in my pocket or her outside of purse.
ANY item that is to enter the house is disinfected with clorox wipes or spray (all sides & top to bottom) in the garage with the bags thrown away first. Once done we disinfect our hands before touching the garage doorknob to enter. We even spray the bottom of our shoes and take turns spray our clothing. We do wear masks when in close proximity to others (grocery store), but only for their assurance.
This is about touching infected surfaces and then touching your face, which most people do dozens of times a day. Masks do nothing as is obvious from this new surge. Keeping hands and objects disinfected is the key.
We don’t know enough about this virus. Maybe we’ll know more in 5 or 10 years. Hopefully the vaccine will work and the virus does not mutate but it might.
