From Wikipedia, the free encyclopedia Streptococcal pharyngitis, also known as strep throat, is an infection of the back of the throat including the tonsils caused by group A streptococcus (GAS). Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the neck. A headache, and nausea or vomiting may also occur.

From Wikipedia, the free encyclopedia A group A streptococcal infection is an infection with group A streptococcus (GAS). Streptococcus pyogenes comprises the vast majority of the Lancefield group A streptococci, and is often used as a synonym for GAS.

The rapid strep test is a rapid antigen detection test that is widely used in clinics to assist in the diagnosis of bacterial pharyngitis caused by group A streptococci, sometimes termed strep throat. There are currently several types of rapid strep test in use, each employing a distinct technology. However, they all work by detecting the presence of GAS in the throat of a person by responding to GAS-specific antigens on a throat swab.
A rapid strep test may assist a clinician in deciding whether to prescribe an antibiotic to a person with pharyngitis, a common infection of the throat. Viral infections are responsible for the majority of pharyngitis, but a significant proportion is caused by bacterial infection. The symptoms of viral and bacterial infection may be indistinguishable, but only bacterial pharyngitis can be effectively treated by antibiotics. Since the major cause of bacterial pharyngitis is GAS, the presence of t
The person’s throat is first swabbed to collect a sample of mucus. In most RSTs, this mucus sample is then exposed to a reagent containing antibodies that will bind specifically to a GAS antigen. A positive result is signified by a certain visible reaction. There are three major types of RST: First, a latex fixation test, which was developed in the 1980s and is largely obsolete. It employs latex beads covered with antigens that will visibly agglutinate around GAS antibodies if these are ...
The specificity of RSTs for the presence of GAS is at least 95%, with some studies finding close to 100% specificity. Therefore, if the test result is positive, the presence of GAS is highly likely. However, 5% to 20% of individuals carry GAS in their throats without symptomatic infection, so the presence of GAS in an individual with pharyngitis does not prove that this organism is responsible for the infection. The sensitivity of lateral flow RSTs is somewhat lower at 65% to 80%. Therefore, a n
Sore throat, also known as throat pain, is pain or irritation of the throat. Sore throat is usually caused by a viral infection or a group A streptococcus bacterial infection. Other causes include pharyngitis, tonsillitis, or dehydration, which leads to the throat drying up. It can also result from trauma. The majority of sore throats are caused by a virus, for which antibiotics are not helpful. A strong association between antibiotic misuse and antibiotic resistance has been shown. For sore thr
A sore throat is the pain felt anywhere in the throat.
The most common cause is acute viral pharyngitis, a viral infection of the throat. Other causes include other bacterial infections, trauma, and tumors. Gastroesophageal reflux disease can cause stomach acid to back up into the throat and also cause the throat to become sore. In children, streptococcal pharyngitis is the cause of 35–37% of sore throats. The symptoms of a viral infection and a bacterial infection may be very similar. Some clinical guidelines suggest that the cause of a sore ...
Pain medications such as non-steroidal anti-inflammatory drugs and paracetamol help in the management of pain. The use of corticosteroids seems to increase the likelihood of resolution and reduce the level of pain. Antibiotics shorten the duration of pain symptoms by an average of about one day. It is not known whether antibiotics are effective for preventing recurrent sore throat. There is an old wives tale that having a hot drink can help with common cold and influenza symptoms, including sore
In the United States, there are about 2.4 million emergency department visits with throat-related complaints per year.
