Prevention and Precaution
There is no vaccine for invasive Group A strep available, although vaccines are in development.
Prophylaxis is when healthcare professionals give antibiotics to someone to prevent them from getting sick. Most people exposed to someone with a group A strep infection should not receive prophylaxis. However, in some situations, healthcare professionals may recommend prophylaxis for someone exposed to an invasive group A strep infection. Invasive group A strep infections include pneumonia, necrotizing fasciitis, and streptococcal toxic shock syndrome.2
Symptoms of invasive Group A strep vary depending on the type of infection. Still, they can include high fever, severe pain, swelling, redness of the affected area, dizziness, confusion, widespread red rash, nausea, vomiting, and abdominal pain. Other concerning signs include difficulty breathing, blue lips, if a person is very sleepy, or having a hard time waking up.

The CDC tracks invasive group A strep infections through its Active Bacterial Core surveillance (ABCs), a population-based, active- and laboratory-based surveillance system. This means local and state health departments routinely contact laboratories to identify all cases and then report those cases to CDC. 3
The outbreak of Group A strep in New Brunswick highlights the critical need for ongoing surveillance, prompt medical care, and community education to mitigate the impact of such infections.
