2. Type of disease
The Methicillin-resistant Staphylococcus Aureus (commonly known as MRSA) is a type of bacteria resistant to treatments of methicillin and penicillin (Fig. 1).
Being hard to deal with antibiotics in case of a breakthrough, this makes MRSA a hard case to deal with.

3. Description of the disease
The MRSA is part of the Staph Bacterial Infections category.
MRSA is not designed to be harmful to humans, but when in contact with open flesh wounds or blood it can cause severe damage (See Fig. 2)
Commonly found inside our nostrils (easily inhaled)

4. History of the disease
In 1880, Sir Alexander Ogston, a surgeon in Scotland, discovered S. aureus while performing knee surgery on one of his patients
The first signs of a MRSA appeared in the late 1960 (U.S.)
The lack of knowledge and use of certain antibiotics for treating S. aureus caused the development of MRSA (See Fig.3)

5. Symptoms of the disease
Skin Infections
Pustules or Boils
First look like spider bites or red bumps
Severe cases can have them develop on greater surfaces
Swells up a great portion of skin, presenting itself as a BREAKOUT

6. Transmission of the disease
MRSA most commonly colonizes:
Nostrils
Respiratory tract
Opened wounds (See Fig. 4.)
Urinary tract
Healthy individuals may carry MRSA from a few weeks to many years
People with weak immune systems are predisposed to get infected faster

7. Where it originated
Although MRSA has traditionally been seen as a hospital-associated infection, community acquired MRSA strains have begun to appear in recent years, notably in the United States and Australia. (See Fig. 5)

8. Cures / treatments
MRSA often results in abscess formation that requires incision and drainage.
70% alcohol has proven to be an effective sanitizer against MRSA
CONCLUSION:
For any type of dermatologic problems, a doctor should be consulted immediately
