If you were outside, your hands got dirty and there was no water and soap available, what would you do to clean your hands? You need to have hand sanitizer with you wherever you go because your hands will always catch bacteria and you will need to use a sanitizer in order to lessen their effect. If you share items used by many people, chances are you will catch an infection or get bacteria on your hands. In this case use a hand sanitizer to clean your hands to lessen.
Most hand sanitizers are able to kill bacteria because of the high alcohol concentration, which dries bacteria, thus killing most of the bacteria on your hands. If you rub the sanitizer on your hand for thirty seconds, it will destroy many dangerous kinds of bacteria. If you use hand antiseptics or sanitizers, the redevelopment of bacteria will take would be slower. Use sanitizers in the right way and you will decrease the growth of bacteria.

You need to use hand sanitizers whenever you are coughing, sneezing, coming in contact with ill people, dealing with pets and using the toilet. You also must use hand sanitizer when touching garbage, pets, or pet food. You apply it by putting some on the palm of your hand and then you rub both your hands together for 30 seconds, until your hands are dry. (http://www.cdc.gov/handwashing/)
Hand sanitizers that contain alcohol are the most effective; they are able to kill bacteria, fungi and certain types of viruses, like the influenza virus. But there are some types of viruses that are not eliminated by hand sanitizer. Those are the types of viruses that have no coat or covering around them.
