Which action Can best to limit the transmission of pathogen’s by direct contact?

The very best way to prevent catching or spreading a pathogen is to wash your hands regularly with soap and water. Wash your hands well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks. You should also wash up after blowing your nose, coughing, or sneezing; feeding or stroking your pet; or visiting or caring for a sick person. Wet your hands thoroughly. Lather up with soap or cleanser, and rub it into the palms and backs of your hands and your wrists. Be sure to clean your fingertips, under your nails and between your fingers. Rinse under running water. Dry your hands and wrists thoroughly.

• Cover a cough. Cover your mouth and nose with a tissue when you sneeze or cough, then dispose of it. If no tissue is handy, cough or sneeze into your elbow rather than into your hands.
• Wash and bandage all cuts. Any serious cut or animal or human bite should be examined by a doctor.
• Do not pick at healing wounds or blemishes, or squeeze pimples.
• Don't share dishes, glasses, or eating utensils.
• Avoid direct contact with napkins, tissues, handkerchiefs, or similar items used by others.
