The two most prominent infections of GAS are both non-invasive: strep throat (pharyngitis) where it causes 15–30% of the childhood cases and 10% of adult cases, and impetigo. [4] These may be effectively treated with antibiotics. Scarlet fever is also a non-invasive infection caused by GAS, although much less common.
Invasive strep infections caused by Group A bacteria are on the rise across the globe. Learn what invasive Group A strep is and why rates are so high this year.
Cases of invasive strep A — a similar type of bacterium that also causes scarlet fever and impetigo — have been increasingly diagnosed over the past decade, but it's the common form of the ...
An estimated 700 million GAS infections occur worldwide each year. While the overall mortality rate for these infections is less than 0.1%, over 650,000 of the cases are severe and invasive, and these cases have a mortality rate of 25%. [4] Early recognition and treatment are critical; diagnostic failure can result in sepsis and death.
The noninvasive infections tend to be more common and less severe. The most common of these infections include streptococcal pharyngitis (strep throat) and impetigo. [13] Scarlet fever is another example of Group A noninvasive infection. The invasive infections caused by group A beta-hemolytic streptococci tend to be more severe and less common.
The U.S. records several million cases of noninvasive group A strep every year, but invasive infections are rare, at around 14,000 to 25,000 cases annually, according to the CDC. Between 1,500 and ...
Unlike a typical strep A infection, an iGAS infection is indicated by signs including high fever, confusion, difficulty breathing, nausea, vomiting and a rash that spreads to the entire body, with ...
