Invasive Strep A Infections Rise Sharply in the US, CDC Reports

A new report from the CDC highlights a concerning trend: invasive group A streptococcus (iGAS) infections have more than doubled in several states over the past decade. While strep throat is a common and usually mild illness, iGAS infections are far more serious and can be life-threatening.

The CDC analyzed data from 10 states between 2013 and 2022 and found a significant increase in iGAS cases. These infections occur when strep A bacteria invade parts of the body where they are not normally found, such as the blood, muscles, or lungs. This can lead to severe conditions like necrotizing fasciitis (flesh-eating disease), streptococcal toxic shock syndrome, and pneumonia.

Symptoms of iGAS infections can vary depending on the site of infection but may include fever, chills, severe pain, redness, swelling, and difficulty breathing. Individuals with underlying health conditions, weakened immune systems, and those who have recently had chickenpox or the flu are at higher risk of developing iGAS infections.

To prevent the spread of strep A, the CDC recommends practicing good hygiene, including frequent handwashing with soap and water, covering coughs and sneezes, and avoiding sharing personal items. Early diagnosis and treatment with antibiotics are crucial for managing iGAS infections. If you suspect you have strep throat or are experiencing symptoms of an iGAS infection, seek medical attention immediately.
