By avoiding contact, the gene therapy will not affect others by accident. Wash hands with soap and water after coming into contact with body fluids and before eating. Use disposable gloves. Place items that have body fluids on them, such as diapers, in a sealed bag. Get rid of the bag in the regular trash.
