If someone in your house has/had a strep infection it is unlikely that it will be spread on household items such as doorknobs and dishes, but I would still use a disinfectant around the house that states it kills strep bacteria.
The good news is that invasive group A-streptococcal disease isn’t really that common, only around ten thousand cases per year occur in the United States, of those approximately twelve hundred will succumb to the illness. Compare that to the several million cases of strep throat and impetigo that occur annually in the U.S. and you will see just how uncommon it is. In recent news a young girl in Georgia was unfortunate enough to contract necrotizing fasciitis while zip-lining with friends.
Fortunately, very few people who come in contact with invasive group A- streptococcal disease will develop a life threatening disease. Most people merely contract a simple throat or skin infection, and still many may have no symptoms at all. Although it is possible for healthy people to contract an invasive group A- streptococcal disease, persons with chronic illnesses such as cancer, diabetes, chronic heart or lung disease, and those who use medications such as steroids have a much greater risk.
Treatment for necrotizing fasciitis may include some or all of the following:
- Surgery that removes infected tissue and fluids to stop the spread of infection.
- Medicines (antibiotics and intravenous immunoglobulin) to kill the bacteria causing the infection.
- Procedures to treat complications such as shock, respiratory problems, and organ failure.
- Hyperbaric oxygen therapy, which can help prevent tissue death and promote healing. WebMD
