Streptococcal pharyngitis
Streptococcal pharyngitis (pronounced: strep-toe-cock-al fair-in-jai-tis), also known as Strep throat, is a type of pharyngitis caused by group A streptococcus bacteria (Streptococcus pyogenes).
Etymology
The term "Streptococcal" is derived from the genus name Streptococcus, which is a group of gram-positive bacteria. "Pharyngitis" comes from the Greek words "pharynx" meaning "throat" and "-itis" meaning "inflammation".
Symptoms
Common symptoms of streptococcal pharyngitis include a sore throat, fever, and swollen lymph nodes in the neck. Other symptoms may include headache, nausea, and rash known as Scarlet fever if left untreated.
Diagnosis
Diagnosis is typically made based on the symptoms and a physical examination of the throat. A throat swab can be taken for a rapid strep test or a throat culture to confirm the presence of group A streptococcus bacteria.
Treatment
Treatment usually involves antibiotics to kill the bacteria, such as Penicillin or Amoxicillin. Over-the-counter pain relievers and home remedies can also help alleviate symptoms.
Prevention
Prevention strategies include good hand hygiene and not sharing personal items like toothbrushes or eating utensils. Vaccines are currently under development but are not yet available.
