Hello, Thnx to contact us. I understand your concern. If I am your treating doctor I advice you that it is not much contagious. In other words it is not as contagious as other disease like swine flu. If you come in contact with the lesion having high bacterial load of the staphylococcus bacteria than it is possible to have this infection. But it can be stopped spreading by taking due care that is proper hand washing, using sanitizer, using proper disinfectants etc. I will be happy to answer more of your concerns, kindly know me, Wish you a very good health at health care magic. Dr. Arun Tank. Infectious Disease.
