Sanitizing could be done by either cleaning, disinfecting, or both. Sanitizing means that you are lowering the number of germs to a safe level. What is considered a safe level depends on public health standards or requirements at a workplace, school, etc. For example, there are sanitizing procedures for restaurants and other facilities that prepare food. What you do to sanitize will vary, depending on your needs. You might be mopping a floor using a mop, a chemical, and water.
Use a hand sanitizer.
Avoid contact with wild animals, farm animals, and birds.
Maintain your immunity with nutritious food, adequate sleep, and regular exercise.
Clean your hands with soap & water frequently.
Avoid close contact with a person having flu-like symptoms.
