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.
Japan is reporting a record number of streptococcal toxic shock syndrome (STSS) cases this year. STSS is a severe, life-threatening complication of Group A Streptococcus, the same bacteria ...
The bacterial species involved in a streptococcosis infection is typically identified through microscopy of the bacteria to observe their morphology, biochemical tests (e.g., hemolysis ability), and tests on which antibodies are produced by the infected organism. [2]
Streptococcal pharyngitis, also known as streptococcal sore throat (strep throat), is pharyngitis (an infection of the pharynx, the back of the throat) caused by Streptococcus pyogenes, a gram-positive, group A streptococcus. [9] [10] Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the front of the neck.
Japanese health authorities have warned about a jump in potentially deadly strep throat infections, with cases running about three times higher than last year in Tokyo. Across the country ...
Invasive group A strep infections were largely curbed by Covid-19 controls, such as masking and social distancing, but after those measures were relaxed many countries reported a rise in cases.
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.
Health agencies are issuing warnings to parents about invasive group A streptococcus (iGAS), a common bacterium that usually causes mild illness but can sometimes result in severe cases and even ...
