CASE A
Maria, a dental hygienist, is air polishing Kyle's teeth.
Kyle is a 9-year-old boy currently undergoing phase I orthodontics. The air temperature in the office is warm today because of a malfunctioning air conditioning unit. Because of this situation, Maria has opted not to use a face mask. She feels that the face shield she is wearing will be adequate protection; she also thinks that a face mask will make it difficult for her to breathe normally and will make her feel more uncomfortably hot. She finishes the treatment and dismisses her client. Two weeks later, vesicles break out all over her skin. Maria visits her health care provider and is diagnosed with chickenpox.
-What is the source of the microbes in this case?

• A)Client's mouth
