Epidemiology

• Discovered in the UK in 1961
• Methicillic-resistant Staphylococcus Aureus
  (MRSA) a.k.a. MURSA
• Worldwide 2 billion people carry some form of
  aureus
• Of the 2 billion 53 million possibly carry MRSA

4
Epidemiology

• In the US 95 million carry aureus in their nose
• Of these 2.5 million carry MRSA

5
Morbidity and Mortality

• CDC estimates that the number of MRSA has doubled
  nationwide 1999 approx. 127,000 up to 2005
  approx. 278,000
• At the same time the amount of deaths increased
  from 11,000 to more than 17,000
• CDC estimates that MRSA would have been
  responsible for 94,360 serious infections and
  associated with 18,650 hospital stay-related
  deaths in the US in 2005

6
Morbidity and Mortality

• Those numbers suggest that MRSA infections are
  responsible for more deaths in the US each year
  than A.I.D.S

Prevention

• WASH YOUR HANDS!!!
• BSI gloves, mask with face shield, gown not a bad
  idea.
• Disinfect you and your equipment including your
  truck.
• This is one virus that does not need open wound
  to enter just contact with your skin.

Treatment

• Abscesses will need to be drained
• Since MRSA is resistant to most antibiotics there
  is research being done to find treatment
• They have found that linezolid, pristinamycin,
  doxycycline, and clindamycin may be effective.
