Streptococcus is a type of bacteria that is commonly found in the human body. While most types of streptococcus are harmless, some strains can cause serious health problems. For example, group A streptococcus (GAS) can cause strep throat, scarlet fever, and invasive infections such as cellulitis and necrotizing fasciitis, also known as flesh-eating disease.

Streptococcus is transmitted through close contact with an infected person, typically through coughing or sneezing. Strep throat is one of the most common types of streptococcus infections and can cause symptoms such as sore throat, fever, and swollen tonsils. Scarlet fever is a more serious form that can cause a rash all over the body in addition to the throat symptoms.

If left untreated, streptococcus infections can lead to more serious complications such as rheumatic fever, which can cause heart damage. It is important to seek medical treatment if you suspect you have a streptococcus infection. Treatment typically involves antibiotics to kill the bacteria and relieve symptoms.

Preventing the spread of streptococcus involves good hygiene practices such as washing your hands frequently and covering your mouth and nose when coughing or sneezing. By taking these simple steps, you can help reduce the risk of spreading streptococcus and keep yourself and others healthy.
