While group A Streptococcus bacteria — also known as Streptococcus pyogenes or Strep A — causes many common conditions such as strep throat and skin infections, invasive group A Streptococcus infections are very dangerous and a medical emergency. It’s these invasive infections that you may have read about lately, and that you may have questions about.
Today in The Conversation Canada, John McCormick and Juan Manuel Diaz of Western University write about what might be causing the international spike in cases, how these infections spread and what symptoms to be aware of.
“Group A Streptococcus can sometimes develop into invasive infections that put patients’ lives at risk, such as necrotizing fasciitis, septicemia (blood poisoning) and streptococcal toxic shock syndrome,” they write. “To generate this wide range of diseases in different parts of the body, the organism has several factors that promote infection and allow the bacteria to invade, colonize and survive in different tissues.”
