117 - Infection Control


This course is mainly concerned with dental health care personnel exposure to pathogenic microorganisms. These organisms include HIV, HBV, HCV, Mycobacterium tuberculosis, Creutzfeldf-Jakob Disease, staphylococci, steptococci, and other virus and bacteria that colonize or infect the oral cavity and respiratory tract.

This includes saliva in dental patients even if no blood is present. Diseases are also transmitted through airborne, droplet, or contact transmission through sneezing, coughing and contact with skin. Examples of these are TB, influenza, and varicella.

ØThere must be a reservoir (source) that allows the pathogen to survive and multiply.

ØThere must be a mode of transmission from the source to the host.

ØThere must be a portal of entry through which the pathogen can....
