Invasive Strep A: The Hidden Danger You Need to Know About
Published: Sep 21, 2023
Invasive Group A Streptococcus (GAS) infections are on the rise and can be life-threatening. While most strep infections are mild, invasive cases can lead to severe complications and even death.
What Exactly is Invasive Strep A?
Invasive Strep A occurs when the bacteria enter parts of the body that are usually germ-free, like your blood or lungs. This is different from common strep throat or skin infections. Invasive Strep A can cause serious conditions like flesh-eating disease, blood poisoning, or toxic shock syndrome.
Who's at Risk?
While anyone can get invasive Strep A, certain groups are more vulnerable. These include adults over 50, young children, pregnant women, and people with weakened immune systems. Other risk factors include having diabetes, using certain medications, or recently having the flu or chickenpox.
Recognizing the Signs
Symptoms of invasive Strep A can vary but often include high fever, severe pain, and feeling very unwell. In some cases, you might see a red rash or notice swelling and redness at a wound site. If you have these symptoms, especially if they come on suddenly or are severe, seek medical attention immediately.
