As an hhs worker, why is it important to be aware of how disease is spread?

The department of health & human services need to know how disease is spread!! If not have infectious disease consultant come out & teach them how to properly clean and explain how easy disease is spread. They do this in the OR at the hospitals.
Disease is spread much easier than we think. Door handles in bathrooms/door handles or someone's cough/sneeze which spreads up to 5 feet.

Laying in tanning beds that haven't been cleaned properly can spread some nasty stuff!
