The other appropriate instruction would be to apply topical antibiotic ointment.
<h3>Impetigo</h3>
It is a pathogenic disease of the skin that is caused by a bacterium known as Group AStreptococcus.
It is highly contagious and characterized by sores around the mouth and the nose.
Thus, apart from asking a patient with impetigo not to touch the wound so as not to contaminate other parts of the body, asking them to apply an antibiotic ointment is appropriate.
