Visitors to a healthcare facility can also spread MRSA. This may be:. When MRSA is suspected to be the cause of an infection, a sample of the bacteria-containing fluid or tissue is obtained and grown in a dish, or cultured. The bacteria grows and can be identified by looking at it under a microscope.
The sample could be:. Special tests called susceptibility testing are done to determine which antibiotics the bacteria are resistant to and which can be used to kill it and stop the infection. MRSA-causing infections can look very similar to those caused by other nonresistant bacteria. They can then use this culture to correctly diagnose MRSA and determine the appropriate treatment.
Obtaining an accurate diagnosis is critical because prompt and appropriate treatment significantly lowers the risk of the infection getting worse and becoming invasive. Most MRSA skin infections are opened via an incision, and the pus is drained. This is usually enough to cure the infection. Antibiotics are often given after drainage if:.

The doctor will make a small cut in the infection to remove the pus. They will also send a sample of the pus to the lab to test for MRSA and other bacteria. This procedure is performed in a sterile setting. What comes from an abscess or boil can be very contagious, so people should avoid draining boils at home. In more serious infections requiring hospitalization, some people may require intravenous antibiotics, including:. In more serious infections requiring hospitalization, doctors can prescribe vancomycin.
Intravenous clindamycin is another option. The doctor may switch the child to oral linezolid thereafter. Until the person sees a medical provider, they should cover the wound to prevent exposing others to the harmful bacteria. Tests typically take 24—48 hours to provide results. New tests may be able to deliver results in approximately 5 hours but are still not readily available. The most common and reliable tests are the nasal and wound swabs. According to Johns Hopkins , the outlook for someone with a MRSA infection is good providing a person receives treatment in time.
If a person develops a skin infection, they may notice a lump, lesion, or abscess that is painful and warm to the touch. They may also notice inflamed skin, pus, and a fever. MRSA is an infection that is resistant to certain antibiotics, including penicillin, which makes it challenging to treat.
