Disinfection & Safety第 19 / 100 题
An esthetician uses the same unwashed makeup brush on two clients. This is an example of what type of transmission?
a.Direct transmission through skin-to-skin contact
b.Airborne transmission through respiratory droplets
c.Indirect transmission through a contaminated object
d.Transmission that cannot occur because makeup contains preservatives
解析
Indirect transmission occurs when a pathogen moves from one person to another by way of a contaminated object such as a brush, implement, or linen. Direct transmission requires person-to-person contact, and airborne transmission travels through droplets or particles in the air. Cosmetic preservatives limit product spoilage but do not disinfect a brush between clients.
