Methicillin-resistant Staphylococcus aureus, commonly known as MRSA, is a type of staph infection. This bacterium has developed resistance to several widely used antibiotics, making it more challenging to treat than other staph infections. While Staphylococcus aureus bacteria often reside harmlessly on the skin or in the nose, they can cause serious infections if they enter the body through a break in the skin, such as a cut or wound. Recognizing the visual signs of a potential MRSA infection is important for prompt identification and appropriate management.
Appearance of MRSA Skin Infections
MRSA skin infections frequently start as small, red bumps that can initially be mistaken for common issues like pimples, bug bites, or even spider bites. A key differentiator is that these lesions often worsen over a few days instead of improving. The appearance can vary significantly depending on the type of skin infection.
One common manifestation is a boil or abscess, which appears as a red, swollen, and painful lump on the skin. These lesions can grow rapidly and may develop a collection of pus or fluid inside, sometimes forming a blister. The skin around the affected area may also become red and inflamed.
Another form of MRSA skin infection is cellulitis, which presents as a spreading area of redness, warmth, and tenderness on the skin. Unlike a localized boil, cellulitis lacks a central point of pus and spreads across the skin surface. Impetigo-like lesions, characterized by crusting sores, can also occur, particularly in children.
Accompanying Symptoms
MRSA skin infections often present with non-visual symptoms. The affected area feels painful or tender to the touch, and the skin around the lesion may feel warm. Swelling may extend beyond the immediate bump or lesion.
As the infection progresses, it might produce pus or other fluid drainage from the lesion. A person may experience systemic symptoms such as a fever or chills, indicating a broader bodily response. Fatigue or a general feeling of being unwell can also accompany these infections. Occasionally, red streaks may spread from the infection site, which can signal that the infection is extending into the lymphatic system.
When to Seek Medical Care
Seek professional medical attention if you suspect a MRSA infection, as early diagnosis and treatment can prevent complications. You should contact a healthcare provider if a skin infection is worsening, not improving within a few days, or is accompanied by a fever. Any skin lesion that is large, intensely painful, or spreading rapidly warrants immediate medical evaluation.
If the infection is located on sensitive areas such as the face, near the eyes, or on the genitals, prompt medical consultation is advised. Individuals with underlying health conditions, such as diabetes or a weakened immune system, should also seek care sooner due to their increased risk of severe infection. Avoid attempting to pop or drain suspected infections at home, as this can worsen the condition or spread the bacteria. A healthcare professional can accurately diagnose the infection and determine the appropriate course of treatment.
