They are caused by Staphylococcus bacteria. They often start on the skin but can move inside the body and cause serious illness. Often they cause boils, pimples, or minor wounds that get red, swollen, and painful. But sometimes they lead to more severe problems like bloodstream infections, pneumonia, or bone infections.
You can catch staph from direct contact with an infected wound or by touching contaminated surfaces. Tight living spaces, shared towels, and sports equipment make spread more likely. People with cuts, weakened immune systems, or chronic conditions are at higher risk. Healthcare settings are common places for tougher strains like MRSA, a staph type that resists many antibiotics.
If you see a red, warm bump that fills with pus or grows quickly, treat it as a possible staph infection. A simple skin infection might look like a pimple or insect bite but feel worse than usual. Watch for fever, spreading redness, severe pain, or any sign that the infection is moving inward. If a sore won’t heal, or you feel generally unwell, go to a clinic or emergency room. For wounds near the eyes, mouth, or on the face, get medical help fast.
Many skin staph infections can be treated by a doctor who will drain the abscess and may prescribe antibiotics. Don’t try to squeeze or lance it yourself — that raises the risk of spreading the bacteria. For mild cases, warm compresses and good wound care help. If antibiotics are needed, use them exactly as prescribed and finish the full course.
To lower your risk, keep cuts clean and covered, wash hands often, and avoid sharing personal items like razors or towels. Clean and disinfect high-touch surfaces at home and in locker rooms. If someone in your household has a staph infection, wash bedding and clothes in hot water and avoid close skin contact until the wound is healed.
If MRSA is suspected, doctors will choose antibiotics that work against resistant strains. Follow their guidance strictly and report if symptoms worsen. Many people recover well with prompt care, and practical steps can stop a single case from becoming a household problem.
Common questions I hear: Can I still go to work or the gym? If your wound is covered and you’re not running a fever, many workplaces will allow light activity, but avoid contact sports and public pools. How long does it take to heal? Small skin infections often improve in a few days after treatment, but full healing can take one to three weeks. If treatment doesn’t help or the infection returns, ask your doctor about culture tests to find the best antibiotic. Don't delay getting help.
