Signs and Symptoms of a MRSA Infection

More Serious MRSA Infection Symptoms

Although less common, community-associated MRSA infections can develop into more serious invasive infections, such as bloodstream infections or pneumonia. This can lead to a variety of other symptoms, including:
  • Shortness of breath
  • Fever
  • Chills
  • Loss of life.
These serious infections are more common in people who have healthcare-associated MRSA. Other types of serious MRSA infections can include infections of the soft tissue (cellulitis), bone (osteomyelitis), or inner lining of the heart (endocarditis).
Community-associated MRSA can be particularly dangerous in children because their immune systems are not fully developed. Therefore, it is important to pay attention to minor skin problems in children, such as pimples, insect bites, cuts, and scrapes. If the wound appears to be infected, see a healthcare provider right away so the problem can be diagnosed.

What Is the Difference Between Regular Staph and MRSA?

There are many types of bacteria that can cause skin infections. Staphylococcus aureus, often referred to simply as "staph," are bacteria commonly carried on the skin or in the nose of healthy people. Approximately 25 to 30 percent of the population is colonized (when bacteria are present, but are not causing an infection) in the nose with staph bacteria.
Sometimes, staph can cause an infection. Staph bacteria are one of the most common causes of skin infections in the United States. Most of these skin infections are minor (such as pimples and boils) and can be treated without antibiotics. However, staph bacteria can cause serious infections (such as surgical wound infections, bloodstream infections, and pneumonia).
Some staph bacteria are resistant to antibiotics. MRSA is a type of staph that is resistant to antibiotics called beta-lactams. Beta-lactam antibiotics include methicillin and other more common antibiotics, such as oxacillin, penicillin, and amoxicillin (Amoxil®). While 25 to 30 percent of the population is colonized with staph, approximately 1 percent is colonized with MRSA.
