Which of the following is considered as the most important aspect of hand wash?

Feces (poop) from people or animals is an important source of germs like Salmonella, E. coli O157, and norovirus that cause diarrhea, and it can spread some respiratory infections like adenovirus and hand-foot-mouth disease. These kinds of germs can get onto hands after people use the toilet or change a diaper, but also in less obvious ways, like after handling raw meats that have invisible amounts of animal poop on them. A single gram of human feces—which is about the weight of a paper clip—can contain one trillion germs 1. Germs can also get onto hands if people touch any object that has germs on it because someone coughed or sneezed on it or was touched by some other contaminated object. When these germs get onto hands and are not washed off, they can be passed from person to person and make people sick.

Handwashing with soap removes germs from hands. This helps prevent infections because:

• People frequently touch their eyes, nose, and mouth without even realizing it. Germs can get into the body through the eyes, nose and mouth and make us sick.
• Germs from unwashed hands can get into foods and drinks while people prepare or consume them. Germs can multiply in some types of foods or drinks, under certain conditions, and make people sick.
• Germs from unwashed hands can be transferred to other objects, like handrails, table tops, or toys, and then transferred to another person’s hands.
• Removing germs through handwashing therefore helps prevent diarrhea and respiratory infections and may even help prevent skin and eye infections.

Teaching people about handwashing helps them and their communities stay healthy. Handwashing education in the community:

• Reduces the number of people who get sick with diarrhea by 23-40% 2, 3, 6
• Reduces diarrheal illness in people with weakened immune systems by 58%  4
• Reduces respiratory illnesses, like colds, in the general population by 16-21% 3, 5
• Reduces absenteeism due to gastrointestinal illness in schoolchildren by 29-57% 7

Preventing sickness reduces the amount of antibiotics people use and the likelihood that antibiotic resistance will develop. Handwashing can prevent about 30% of diarrhea-related sicknesses and about 20% of respiratory infections (e.g., colds) 2, 5. Antibiotics often are prescribed unnecessarily for these health issues 14. Reducing the number of these infections by washing hands frequently helps prevent the overuse of antibiotics—the single most important factor leading to antibiotic resistance around the world. Handwashing can also prevent people from getting sick with germs that are already resistant to antibiotics and that can be difficult to treat.

Handwashing is one of the best ways to protect yourself and your family from getting sick. Learn when and how you should wash your hands to stay healthy.

How Germs Spread

Washing hands can keep you healthy and prevent the spread of respiratory and diarrheal infections. Germs can spread from person to person or from surfaces to people when you:

• Touch your eyes, nose, and mouth with unwashed hands
• Prepare or eat food and drinks with unwashed hands
• Touch surfaces or objects that have germs on them
• Blow your nose, cough, or sneeze into hands and then touch other people’s hands or common objects

Key Times to Wash Hands

You can help yourself and your loved ones stay healthy by washing your hands often, especially during these key times when you are likely to get and spread germs:

• Before, during, and after preparing food
• Before and after eating food
• Before and after caring for someone at home who is sick with vomiting or diarrhea
• Before and after treating a cut or wound
• After using the toilet
• After changing diapers or cleaning up a child who has used the toilet
• After blowing your nose, coughing, or sneezing
• After touching an animal, animal feed, or animal waste
• After handling pet food or pet treats
• After touching garbage

If soap and water are not readily available, use a hand sanitizer with at least 60% alcohol to clean your hands.

Follow Five Steps to Wash Your Hands the Right Way

Washing your hands is easy, and it’s one of the most effective ways to prevent the spread of germs. Clean hands can help stop germs from spreading from one person to another and in our communities—including your home, workplace, schools, and childcare facilities.

Follow these five steps every time.

1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
4. Rinse your hands well under clean, running water.
5. Dry your hands using a clean towel or an air dryer.

Use Hand Sanitizer When You Can’t Use Soap and Water

Washing hands with soap and water is the best way to get rid of germs in most situations. If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label.

Sanitizers can quickly reduce the number of germs on hands in many situations. However,

• Sanitizers do not get rid of all types of germs.
• Hand sanitizers may not be as effective when hands are visibly dirty or greasy.
• Hand sanitizers might not remove harmful chemicals like pesticides from hands.

How to Use Hand Sanitizer

1. Apply the gel product to the palm of one hand (read the label to learn the correct amount).
2. Cover all surfaces of hands.
3. Rub your hands and fingers together until they are dry. This should take around 20 seconds.
