I was hazmat certified (full-week course with yearly updates required) and also a health and safety officer (additional training) – part of my work duties to be so – for about 20 years. I worked at hazardous waste sites doing clean ups and etc*.
Anyway in times as these; what I learned and practiced is useful and that base of knowledge and fundamental understanding is critical. And that keeps your mind in a rational state – instead of the fear, panic and frenzy that animates so many.
A ten percent solution of bleach and water is very effective in sanitizing surfaces against germs (germ being a generic term for both bacteria and virus). Plain soap and warm water cleanses the hands efficiently (rub between all fingers) with a few minutes of washing – get under your nails also. Use a soft brush if necessary. Avoid touching your face altogether. Disinfecting can also be effectively done with hard liquor – we, on occasion (no joke) would use Everclear to decontaminate some sampling equipment. If you purchase something that is anti-bacterial ONLY; it has little to no effective use against a virus. For example, it is the soap and washing that decontaminates your hands – not the anti-bacterial agent in the soap or anti-bacterial wipes. So plain soap is all that is required for washing and virus decon. Using anti-bacterial soap is not a bad idea it is just not 100% necessary for viruses.
There is a fundamental difference between virus and bacteria. Viruses are microscopic parasites, generally much smaller than bacteria. They lack the capacity to thrive and reproduce outside of a host body [they can 'live' for a few hours on surfaces depending on type]. How much smaller are most viruses in comparison to bacteria? Quite a bit. With a diameter of 220 nanometers, the measles virus is about 8 times smaller than E.coli bacteria.
Bacteria are microscopic, single-celled organisms that exist in their millions, in every environment, both inside and outside other organisms. Some bacteria are harmful, but most serve a useful purpose. They support many forms of life, both plant and animal, and they are used in industrial and medicinal processes.

*Nitrile gloves are used by hazmat and health care workers for hand protection. (Hazmat workers have 4 levels of protection: Level A, B, C, and D). I’ve worked in level C which included a full-face respirator. Screw-on Cartridges provide respiratory protection and different cartridges are used for different potential hazards; from Biological to Radioactive. I only had to work in level B a few times which includes supplied air (SCUBA).
