Four areas Tuberculosis is more likely to develop.
Special immune cells that form a hard shell that keep the bacilli contained and under control (latent).
When the immune system cannot keep bacilli under control (active), the hard shell breaks down and tubercle bacilli escape and begin to multiply rapidly.

Extensively drug-resistant Tuberculosis
Blood borne pathogens
Pathogenic microorganisms that are present in human blood and can cause disease in humans.
Hepatitis B, Hepatitis C, HIV/AIDS
Three diseases caused by blood borne pathogens.
An inflammation of the liver caused by a virus
HAV, HBV, HCV, HDV, HEV
Five types of viral hepatitis.
Hepatitis B Disease
Caused by HBV
Hepatitis C Disease
Caused by HCV
Hepatitis D Disease
Caused by HDV
Hepatitis E Disease
Caused by HEV
Hepatitis Disease that enters via the gut, replicates in the digestive system and spreads to infect the liver, where it multiplies in the hepatocytes cells.
Hepatitis Disease spread from person to person by fecal-oral transmission by eating food handled by a person with HAV who did not wash his/her hands properly after using the washroom, eating raw or undercooked seafood from sewage-polluted water, eating salad that has been rinsed in contaminated water and swimming in contaminated water.
Hygiene, gamma globulin injection, vaccine
Three Hepatitis A Disease prevention methods.
Hepatitis Disease caused by a hepatitis virus that replicates in the liver. Virus particles, as well as excess viral surface protein, are shed in large amounts into the blood (highly infectious).
Two types of Hepatitis B infections.
A hepatitis B infection that may last up to six months.
A hepatitis B infection that occurs if acute hepatitis infection is not resolved within six months.
A rare, severe and rapidly progressive form of hepatitis accompanied by hepatocellular death and the signs and symptoms of hepatic failure.
An infection where there is no sign of symptoms.
A chronic disease of the liver caused by the destruction of cells, and inflammation.
Prolonged illness, liver cancer, cirrhosisis, liver failure, death
Five consequences of being a hepatitis B carrier.
Blood transfusion, manicure or pedicure, tattoo or piercing, acupuncture, shaving, sexual contact, medical or dental procedure, sharing personal hygiene items, mother to newborn at birth
Nine modes of Hepatitis B transmission.
Saliva, genital fluids, breast milk, synovial fluid, amniotic fluid, cerebrospinal fluid, peritoneal fluid
Seven fluids that may contain Hepatitis B.
Vaccine, HBIG, PPE
Three preventive measures health care workers should take against Hepatitis B.
Blood transfusion, needles, sexual contact
Three ways of transmission of hepatitis C
fatigue, cirrhosis, liver cancer, non-Hodgkin lymphoma
Four symptoms of Hepatitis C.
The carrier rate of hepatitis C infections becoming chronic.
Screening blood products, routine precautions
Two hepatitis C preventative procedures for health care workers.
A defective virus that cannot replicate itself without the presence of HBV.
Transmitted by way of the fecal-oral routes through contaminated food or water. However, transmission is not a major concern in a standard dental setting.
A blood borne viral infection in which the body's immune system breaks down.
Human Immunodeficiency Virus.
A disease caused by HIV, and identified when a person becomes sick with one or more serious illnesses and infections (opportunistic infections or cancers).
Acquired Immunodeficiency Syndrome
Blood, Semen, vaginal fluid, breast milk, fluid surrounding unborn baby, body fluid containing blood
Six body fluids containing HIV.
unprotected sex, needles, blood transfusion, babies born to HIV infected mothers, breastmilk
Five ways HIV is transmitted.
Significant blood exposure
Occurs when an individual has come into direct contact with human blood and/or body fluids infected with HIV, HBV or HCV, including any body fluids visibly soiled or contaminated by blood.
feces, genital secretions, saliva
Three examples of significant blood exposure
The physical removal of visible foreign material from objects and surfaces.
The process that kills all microorganisms and their products (spores).
Reduction or destruction of microorganisms; does not kill spores.
Protective measures to maintain a healthy, disease and hazard-free environment.
To kill or inhibit growth of microorganisms to prevent infection.
The state of being free of pathogenic microorganisms and contaminants.
Cleaning and disinfecting for inanimate objects.
Cleaning and disinfecting for the skin.

Dry Heat Sterilization
Use hot air and transfer the heat to materials.
Machine used to sterilize dental instruments using steam under pressure.
The autoclaves recommended temperature setting.
The autoclaves recommended pressure setting.
The autoclaves recommended time setting.
Physical, Chemical, Biological
Three forms of sterilization monitoring.
Sterilization monitoring that involves observing gauges and readings.
Sterilization monitoring that involves the use of a heat-sensitive chemical that changes color under the right conditions
A type of chemical sterilization monitoring method that is placed outside instrument packages, and only indicates exposure temperature.
A type of chemical sterilization monitoring method that is placed inside instrument packages, and indicates exposure temperature, pressure and time.
Process Indicators, Process Integrators
Two types of chemical sterilization monitoring methods.
Sterilization monitoring method that is the only way to ensure destruction of all microorganisms and spores (sterilization) has occurred.
