Symptoms may include:. Osteomyelitis is another name for a bone infection. When MRSA causes an infection in a bone, symptoms include:. MRSA is very contagious. MRSA only causes an infection when it finds an opening such as a cut and enters your skin or body. MRSA is transmitted through contact with someone who has the infection or any object or surface that has the bacteria on it.
This includes:. 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:.

Centers for Disease C, Prevention. HA-MRSA infections usually are associated with invasive procedures or devices, such as surgeries, intravenous tubing or artificial joints. HA-MRSA can spread by health care workers touching people with unclean hands or people touching unclean surfaces.
Another type of MRSA infection has occurred in the wider community — among healthy people. It's usually spread by skin-to-skin contact. At-risk populations include groups such as high school wrestlers, child care workers and people who live in crowded conditions. MRSA infections start out as small red bumps that can quickly turn into deep, painful abscesses. Staph skin infections, including MRSA , generally start as swollen, painful red bumps that might look like pimples or spider bites.
The affected area might be:. These red bumps can quickly turn into deep, painful boils abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin. But they can also burrow deep into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs. Keep an eye on minor skin problems — pimples, insect bites, cuts and scrapes — especially in children.
