Bloodborne diseases can be transmitted by
infected blood entering the bloodstream
Healthcare-associated infection (HAI)
infections acquired in healthcare settings during the delivery of medical care
infection prevention
methods practiced in healthcare facilities to prevent and control the spread of disease
Infection
occurs when pathogens invade the body and multiply
Standard precautions should be practiced

transmission-based precautions
used in addition to standard precautions for patients with suspected infection Include airborne, droplet, or contact precautions

Reservoir
where pathogens live and multiply
5 Chains of infection
1. Causative Agent 2. Reservoir 3. Portal of exit 4. Mode of transmission 5. Portal of entry 6. Susceptible host

Standard Precautions
A strict form of infection control that is based on the assumption that all blood and other body fluids are infectious.
