On it's own, hand washing most likely won't even help. Cleaning your phone and high contact surfaces will. You need to stop the transfer from surface to surface to face. This is an issue with personal contact with contaminated surfaces. It lives for up to 3 days. https://time.com/5801278/coronavirus-stays-on-surfaces-days-tests/ Unused surfaces will eventually die out (most quicker). That's why the quarantines eventually work. However there is a quicker way to beat this. THE MEDIA. They need to refocus efforts on personal decontamination. You need to have a daily alert for everyone to clean all frequently used surfaces. Money needs to be phased out as much as possible for other alternatives such as e-pay (China tried to clean it, that's not necessary today). You need to run a media blitz every day sponsored by the CDC on all media outlets to disinfect ANY AND ALL frequently used surfaces EVERY DAY for a short period of time. There aren't a lot. -Your ***cell phone*** This is the killer, everyone is using this right after touching contaminated surfaces. -Your wallet -Your credit card -Your steering wheel etc. DO THIS 2-3x per day and for a week and you will DRASTICALLY slow down and stop the spread of this virus. But it needs to be done continuously by as many people as possible. AND IT NEEDS TO BE DONE SOON. Right now we've got idiots stocking up on toilet paper. This isn't going to do a thing. Entering high traffic areas such as stores all at once is only going to increase the spread quicker. You're going to touch stuff in the store, touch your phone, WASH YOUR HANDS(like the CDC says), and then go right back to your phone and eventually transfer it to something else or infect yourself. You need to clean these surfaces more often than your hands.
