Signs & Symptoms of Mercer Disease

By Jaclyn Castek

Mercer disease is a highly contagious disease. It's also known as MRSA because it is caused by methicillin resistant staphylococcus aureus bacteria. This staph bacterium is hard to kill because it has developed immunity to antibiotics, but it can be done. Being aware of the symptoms of MRSA can help ensure the successful treatment of the disease before the bacterium grows to an uncontrollable level.

Skin Symptoms

MSRA most often makes itself known by appearing as a skin infection, also called staph infections. These infections often produce a blistery rash, painful boils or abscesses that are red, swollen and contain pus. A mistake commonly made when the staph infections first appears is that it is a spider bite. If you think this is the case, continue to keep an eye on it and if it does not get better after four days, see a doctor.


Staph infections can also affect the lungs and eventually cause a form of pneumonia called Staphylococcal pneumonia. MRSA that originates in the lungs includes the flu-like symptoms such as shortness of breath and coughing accompanied by fever and chills. When someone has lungs infected by MRSA, the chance for spreading the bacteria through the air drastically increases.

Additional Internal Symptoms

Because MRSA has the ability to attack and infect almost any part of the body, it can manifest in a number of ways. Some of the more common ways are low blood pressure, joint pain, severe headaches, fever and chills.


Organs that often become infected with MRSA are the bladder and urinary tract, as well as the heart and bloodstream. If not treated, it can lead to fatal complications.


MRSA is an extremely contagious disease that can be spread by touching, kissing, breathing or sharing drinks and food. Because MRSA is so highly contagious, protecting yourself against infection is the best form of prevention. You can boost your immune system by maintaining good hygiene, eating a healthful diet and taking immune boosting vitamins, such as vitamins A, D and C.
