I know one can't become paranoid and wear white gloves all the time, that would be ridiculous but there are many small ways one can limit the chance of infection.
My husband and I were talking about that this evening and we decided to not offer our hands for a shake anymore, at least if we remember, just tell a person that we are pleased to meet them but would prefer not to shake hands, if they don't like it too bad. Maybe the Japanese greeting of a respectful little bow would be more fitting these days, what do you think?
The Mayo Clinic says:
The length of time that cold and flu viruses can survive outside the body on an environmental surface varies greatly. But the suspected range is from a few seconds up to 48 hours, depending on the specific virus and the type of surface.
Flu viruses tend to live longer on surfaces than cold viruses. Also, it is generally believed that cold and flu viruses survive for longer periods on nonporous surfaces — such as plastic, metal or wood — than they do on porous surfaces — such as fabric or paper.
Although cold and flu viruses primarily spread from person-to-person contact, they can also spread from contact with contaminated objects or surfaces. The best way to avoid becoming infected with the cold or flu virus is to wash your hands frequently with soap and water or alcohol-based hand sanitizer.
