Keeping hands clean through improved hand hygiene is one of the most
important steps we can take to avoid getting sick and spreading germs to
others. Many diseases and conditions are spread by not washing hands with
soap and clean, running water. If clean, running water is not accessible, as
is common in many parts of the world, use soap and available water. If soap
and water are unavailable, use an alcohol-based hand sanitizer that contains
at least 60% alcohol to clean hands.
Washing hands with soap and water is the best way to reduce the number of
germs on them in most situations. If soap and water are not available, use
an alcohol-based hand sanitizer that contains at least 60% alcohol. Alcohol-
based hand sanitizers can quickly reduce the number of germs on hands in
some situations, but sanitizers do not eliminate all types of germs and might
not remove harmful chemicals.
