Is staff infection contagious? how would or could my children get infected by me if this is a form of staff on my hands and other various places body

Yes/Contact: Staph is a bacteria and gabillions of them are everywhere. When we get colonnized with this, it is easy to spread from one to another. If you are a health care worker, you may have a particularly more virulent form of staph. Today, it is everywhere. Good hygiene, laundry care, bed linen changing and hand sanitizers and soap and water are the best protection.

See previous answer: A staph infection (if that is indeed what you have) is potentially contagious by direct contact with the infected skin. If your skin lesions have pus in them then a culture should be done. This is really the only way to confirm a staph infection. If you haven't already done so i suggest you see a dermatologist to sort things out. He/she may want to do a skin biopsy to clarify your diagnosis.
