Group A Streptococcus (group A strep bacteria) are bacteria that the Centers for Disease Control and Prevention (CDC) reports can cause many different infections, ranging from minor to serious. The agency also warns the bacteria, of which Streptococcus pyogenes is the predominant species, can cause inflammatory diseases.
Examples of minor infections listed include impetigo, scarlet fever, and strep throat. Some of the serious infections listed by the CDC include cellulitis, necrotizing fasciitis, and streptococcal toxic shock syndrome. Inflammatory diseases include post-streptococcal glomerulonephritis and rheumatic fever.
Some people may be at increased risk of getting a serious group A strep infection, according to the CDC. These include people with some viral infections and various medical conditions.
The agency goes on to warn that group A strep bacteria are very contagious and that some infected people don't have symptoms or seem sick, but they can still spread the bacteria to others. It is generally spread through respiratory droplets or direct contact, and potentially by touching contaminated surfaces or objects.
The CDC also cautions that group A strep bacteria can cause clusters and outbreaks of invasive disease, and that the most common clusters and outbreaks investigated in the United States occur in long-term care facilities. The agency also lists other settings for outbreak investigations.
These are just a few of the many things to know about group A strep exposure risks. To learn more about this or other infection control, environmental, health, or safety issues, please visit the websites shown below.
