Virus DHO chapter 14

Viruses Smallest microorganism Visible only with electron microscope Cannot reproduce unless inside another living cell Spread from human to human by blood and other body secretions

Viruses Difficult to kill because they are resistant to many disinfectants Not killed by antibiotics Mutate and change genetic information so new and different viruses emerge constantly Viruses that infect animals can mutate to infect humans with lethal results (SARS, WNV, monkeypox, ebola, Marburg)

Viruses 3 viral diseases of concern for HCW: HCV, HBV, HIV 3 shot vaccine is available for HBV Federal law requires employers provide HBV vaccine at no cost to any at risk HCW

Chicken pox

Common cold

H5N1 (bird flu)

Hepatitis B

Hepatitis C

Famous People with Hep C

Human Immunodeficiency Virus (HIV)

Herpes

Influenza

Marburg

Measles

Monkey pox

Mumps

Polio

Severe Acute Respiratory Syndrome (SARS)

Warts

West Nile Virus
