Group A Streptococcus bacteria is a common bacteria which is found in the throat or skin.

  As a result, these bacteria can cause common illnesses, including the classic strep throat as well as other skin infections, such as impetigo.  

Most strep A infections are mild and easily treated with antibiotics, but some are more serious.

Invasive strep is a rare but severe form of Group A Strep infections, where the bacteria can invade other organ systems such as the blood, skin, lungs, or fatty tissue. The good news is that invasive strep is also treatable with antibiotics.

The key lies in early recognition and isolation to prevent spread of the disease. 

Consult your doctor if your child is sick with:

  • Flu-like symptoms, such as a high temperature, swollen glands, dizziness, lethargy or an aching body
  •  Sore throat
  •  A rash that feels rough, like sandpaper 
  •  Scabs and sores, pain and swelling
  •  Severe muscle aches
  •  Nausea and vomiting

 We can test for this disease, and begin antibiotics as needed.
