Household bleach to be used as a spray for disinfection: I strongly recommend against that. Its highly caustic properties can easily cause painful burns on the skin, respiratory problems, and blindness in eyes.
It really upsets me when I hear on radio or see on TV newscasts some groups of people dutifully “disinfecting” whole streets by spraying them with “disinfectants” of one kind or another.
Of course, washing hands is always a good first step. And the health authorities’ advice in that regard is certainly good, like the information at Canada’s website shown nearby.
