Department of Public Health - Acute Communicable Disease Control

Transmission Based Precautions: Infectious Disease Prevention Posters
These signs aim to help healthcare workers remember when certain precautions are necessary to help prevent infections and save lives. These Transmission Based Precautions are in addition to Standard Precautions as a part of a basic infection prevention and control program. They are used anytime there is a known potential for spreading infectious agents. The appropriate transmission based precaution is determined by the type of organism and how it is usually transmitted.

For additional guidance on infection control in your facility, please contact the Healthcare Outreach Unit: HAI@ph.lacounty.gov

The following posters can be printed or downloaded.
