is caused by a bacteria known as group A beta-haemolytic streptococcus. It is a common infection that can occasionally lead to serious complications such as rheumatic fever and kidney disease. Group A streptococcus can also cause flesh eating disease but this is extremely rare. Streptococcal skin infection
(Impetigo) is usually superficial but may later cause kidney disease.
Group A strep infections can spread from person to person by direct contact with saliva or nasal discharge. Most people do not get group A strep infections from casual contact with others, but a crowded environment like a dormitory, school, or an institutional setting can make it easier for the bacteria to spread
Occasionally streptococcal infection

Post-streptococcal glomerulonephritis (PSGN) is an uncommon complication of either a strep throat or a streptococcal skin infection. It is classified as a type III hypersensitivity
reaction. Symptoms of PSGN develop within 10 days following a strep throat or 3 weeks following a GAS skin infection
. PSGN involves inflammation of the kidney. Symptoms include pale skin, lethargy, loss of appetite, headache and dull back pain. Clinical findings may include dark-colored urine, swelling of different parts of the body (edema), and high blood pressure
. Treatment of PSGN consists of supportive care.
