Select anything below that may spread infection in a healthcare setting.

Answer
A
improperly cleaned medical equipment
B
hands
C
catheters
D
alcohol-based hand sanitizer
E
coughs

Explanation

Improperly cleaned equipment, hands, and catheters can carry germs from one person or surface to another. Coughs can spread infectious droplets through the air. Alcohol-based hand sanitizer is used to reduce germs on hands, so it is not typically a source of infection when used properly.
