Summarize the following:
In the first couple of days of infection, especially, it's a good idea to stay home from work or to keep your child home from school or daycare. You remain contagious for up to 2 days after starting treatment. Children can return to school 24 hours after antibiotic treatment has started. Cover all impetigo sores with a watertight dressing, and make sure the child keeps them covered while at school. Encourage children to wash their hands as well. Use clean, running water and soap to wash your hands frequently throughout the day. If soap is not available, use a hand sanitizer with at least 60% alcohol.  The CDC recommends that you wash your hands for at least 20 seconds, or about the time it takes to sing "Happy Birthday" twice through.  Good handwashing hygiene can help avoid the spread of impetigo. Any contact with the discharge from the sores can pass the rash. Nasal discharge can also pass the rash. Washing your hands frequently reduces the likelihood of spreading discharge around. Impetigo is easier to spread when the environment is wet and humid. Air conditioners already take some of the humidity out of the air of your home, but if you live in an especially humid climate, you might want to invest in a dehumidifier for your home. The easiest way for impetigo to enter your body is through a cut or scrape. If you or your loved one has cuts, be sure to cover them up with band-aids or clean gauze to provide protection. Whether you have impetigo or someone you know does, make sure that person keeps her towels and clothes to herself and doesn't share with other people in the family. It's easy to pass the rash if cloth has been rubbed on the infected area.  Do not share razors or other personal care products with people who have impetigo.  Wash the infected person's clothes and towels daily, by themselves. Use hot water when washing them.

Summary:
Avoid other people. Wash your hands regularly. Dry out your home. Cover cuts and scrapes. Don't share with a person who has impetigo.
