The most common symptoms of strep throat include:Sore throat that can start very quickly.Pain when swallowing.Fever.Red and swollen tonsils, sometimes with white patches or streaks of pus.Tiny, red spots (petechiae — pronounced pi-TEE-kee-eye) on the roof of the mouth (the soft or hard palate)More items...
What is the most common cause of acute pharyngitis?
Most cases of acute pharyngitis are caused by respiratory viruses and are self-limited. However, symptoms of viral pharyngitis broadly overlap with pharyngitis caused by important treatable causes, such as group A Streptococcus (GAS).
What are the signs and symptoms of acute pharyngitis?
Symptoms of acute pharyngitisSore throat.Pain or difficulty when swallowing or talking.Swollen, sore glands in the neck or throat.Red throat and red, swollen tonsils.A hoarse voice.White or grey patches on the back of the throat.
What is the treatment of acute pharyngitis?
Rest, oral fluids, and salt-water gargling (for soothing effect) are the main supportive measures in patients with viral pharyngitis. Analgesics and antipyretics may be used for relief of pain or pyrexia. Acetaminophen is the drug of choice. Traditionally, aspirin has been used, but it may increase viral shedding.
How do I get acute pharyngitis?
It is usually caused by viral and/or bacterial infections, such as the common cold and flu (both viral infections) or by infection with the Streptococcus bacterium (strep throat). Pharyngitis can also occur with mononucleosis (aka “mono”), a viral infection.
What happens if pharyngitis is left untreated?
Left untreated, pharyngitis can, in rare cases, lead to rheumatic fever or sepsis (bacterial blood infection), which are life-threatening conditions.
How long does acute pharyngitis last?
Acute pharyngitis is more common than chronic pharyngitis. Treatment involves treating the symptoms, and it usually goes away within 10 days. In comparison, chronic pharyngitis lingers for much longer — often for several weeks.
What is the difference between strep throat and pharyngitis?
Strep throat: The bacteria group A Streptococcus is the most common cause of strep throat. Sore throat (viral pharyngitis): Viruses are the most common cause of sore throat, including rhinoviruses or a respiratory syncytial virus. These viruses can cause other symptoms, such as: a cold.
How long are you contagious with acute pharyngitis?
How long could you be contagious with a sore throat or strep? Three to four weeks if left untreated. You could be contagious with strep 24 to 48 hours after you start antibiotics.
Which drug is best for pharyngitis?
Penicillin and amoxicillin are the antibiotics of choice for the treatment of pharyngitis.
Can you be hospitalized for strep throat?
Though strep throat (streptococcus) is often very painful and highly contagious, it doesn't often require a trip to the emergency room. However, in some rare cases, patients with extreme symptoms should seek emergency medical attention for proper care.
What is the best antibiotic for pharyngitis?
Penicillin or amoxicillin is the antibiotic of choice to treat group A strep pharyngitis. There has never been a report of a clinical isolate of group A strep that is resistant to penicillin.
What causes pharyngitis?
The most common cause of a sore throat (pharyngitis) is a viral infection, such as a cold or the flu. A sore throat caused by a virus resolves on its own. Strep throat (streptococcal infection), a less common type of sore throat caused by bacteria, requires treatment with antibiotics to prevent complications.
Why do I keep getting pharyngitis?
Chronic pharyngitis is a persistent sore throat that lingers for a few weeks or returns frequently. Chronic pharyngitis may be caused by infection, environmental pollutants, allergies or acid reflux. Treatment involves addressing the underlying cause.
How long does acute pharyngitis last?
Viral pharyngitis often goes away in five to seven days. If you have bacterial pharyngitis, you will feel better after you have taken antibiotics for two to three days. You must take your antibiotic even when you are feeling better. If you don't take all of it, your sore throat could come back.
Is acute pharyngitis contagious?
Yes, pharyngitis (viral and bacterial) is contagious and can be transmitted from one person to another. Usually, mucus, nasal discharge and saliva can contain the viruses and/or bacteria that can cause sore throat. Consequently, even kissing can cause transfer of these organisms.
What are the complications of pharyngitis?
One significant complication of pharyngitis in general is dehydration. Young patients may have a history of decreased oral intake or poor feeding. It is important to assess oral intake and screen for dehydration in these patients. The physical exam in streptococcal pharyngitis is somewhat classic.
How Common is Group A Strep?
Group A Streptococcus, or Streptococcus pyogenes is the most common cause of bacterial pharyngitis, accounting for up to 30% of sore throats in the winter and early spring in children.
What is the centor score for strep?
Scores of 3 to 4 have a high probability of strep as a cause of the sore throat, some sources suggesting up to 70 to 80%. Some sources state that patients with very high Centor Score should be given antibiotics without testing, however this decision is clinician dependent and should take into account the whole clinical picture.
How much strep can be missed?
The rapid tests may have a false negative of up to 10%. Some sources suggest that up to 30% of strep can be missed via rapid antigen testing.
How many visits to the doctor for sore throat?
Given the almost 30 million visits per year for sore throat, it is important for clinicians and students alike to master the diagnosis.
Can strep cause a sore throat?
Patients with streptococcal pharyngitis typically will complain of odynophagia, sore throat, hoarseness, and abrupt onset of headache, chills or malaise. There may be a history of interaction with a classmate or contact that was diagnosed with the disease. Of note, the symptoms of cough, coryza, and diarrhea should point the clinician in the direction of viral etiology, as these are usually not seen in strep.
When is sore throat most common?
The disease is most common in the winter months and early spring. There can be isolated outbreaks in schools or families. Other considerations in the differential diagnosis for sore throat include numerous viral causes, Haemophilis influenza, Herpes Simplex, Moraxella Catarrhalis, peritonsillar abscess, dental abscess, esophageal reflux, and post nasal drip.
What causes a pharynx infection?
Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine.
Why is a Throat Culture underused?
However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results.
What are the symptoms of streptococcal pharyngitis?
The typical signs and symptoms of streptococcal pharyngitis are a sore throat, fever of greater than 38 °C (100 °F), tonsillar exudates ( pus on the tonsils ), and large cervical lymph nodes.
What is a culture positive case of streptococcal pharyngitis?
A culture positive case of streptococcal pharyngitis with typical tonsillar exudate in a 16-year-old. 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).
How long does it take for pharyngitis to resolve?
Untreated streptococcal pharyngitis usually resolves within a few days. Treatment with antibiotics shortens the duration of the acute illness by about 16 hours. The primary reason for treatment with antibiotics is to reduce the risk of complications such as rheumatic fever and retropharyngeal abscesses.
What is the sensitivity of a throat culture?
A throat culture is the gold standard for the diagnosis of streptococcal pharyngitis, with a sensitivity of 90–95%. A rapid strep test (also called rapid antigen detection testing or RADT) may also be used. While the rapid strep test is quicker, it has a lower sensitivity (70%) and statistically equal specificity (98%) as a throat culture. In areas of the world where rheumatic fever is uncommon, a negative rapid strep test is sufficient to rule out the disease.
What is the best antibiotic for pharyngitis?
The antibiotic of choice in the United States for streptococcal pharyngitis is penicillin V, due to safety, cost, and effectiveness. Amoxicillin is preferred in Europe. In India, where the risk of rheumatic fever is higher, intramuscular benzathine penicillin G is the first choice for treatment.
How many people have pharyngitis?
Pharyngitis, the broader category into which Streptococcal pharyngitis falls, is diagnosed in 11 million people annually in the United States. It is the cause of 15–40% of sore throats among children and 5–15% in adults. Cases usually occur in late winter and early spring.
What are the red spots on the soft palate?
Note the petechiae, or small red spots, on the soft palate. This is an uncommon but highly specific finding in streptococcal pharyngitis.
What causes pharyngitis?
Acute pharyngitis can be caused by a variety of viral and bacterial pathogens, including group A Streptococcus (GAS), as well as fungal pathogens ( Candida ). Bacterial pharyngitis is more common in winter (or early spring), while enteroviral infection is more common in the summer and fall. Acute pharyngitis is generally a self-limited condition ...
Can antibiotics prevent gas infections?
The only situation in which antibiotic prophylaxis to prevent GAS infections is recommended is for individuals with a history of rheumatic fever.
Definition
Acute pharyngitis is characterized by the rapid onset of sore throat and pharyngeal inflammation (with or without exudate). Absence of cough, nasal congestion, and nasal discharge suggests a bacterial, rather than viral, etiology.
Epidemiology
Bacterial pharyngitis is more common in winter (or early spring), while enteroviral infection is more common in the summer and fall. [ 2] Pharyngitis is most common in school-aged children during the winter months. Seasonal colonization with group A Streptococcus (GAS) reaches its peak (up to 20% of children) during this season.
Etiology
Acute sore throat is most commonly due to viral organisms or group A Streptococcus (GAS). Common viral causes include the Epstein-Barr virus (mononucleosis), adenoviruses, enteroviruses, influenza A and B, and parainfluenza.
Pathophysiology
Acute pharyngitis results from infection and inflammation of the pharynx, the details of which are both pathogen- and host-specific. Most commonly the disease is localized to the pharynx alone, but rarely it may be part of a systemic infection (e.g., infectious mononucleosis, tularemia, or HIV).
Guidelines for Treatment
Although GABHS pharyngitis is common, the ideal approach to management remains a matter of debate. Numerous practice guidelines, clinical trials, and cost analyses give divergent opinions. U.S. guidelines differ in whether they recommend using clinical prediction models versus diagnostic testing ( Table 4 ).
Management of Recurrent GABHS Pharyngitis
RADT is effective for diagnosing recurrent GABHS infection. In patients treated within the preceding 28 days, RADT has similar specificity and higher sensitivity than in patients without previous streptococcal infection (0.91 versus 0.70, respectively; P < .001).
Chronic Pharyngeal Carriage
Chronic pharyngeal carriage is the persistent presence of pharyngeal GABHS without active infection or immune/inflammatory response. Patients may carry GABHS for one year despite treatment. Chronic carriers are at little to no risk of immune-mediated post-streptococcal complications because no active immune response occurs.
Tonsillectomy
The effect of tonsillectomy on decreasing risk for chronic or recurrent throat infection is poorly understood. One trial in children showed that the frequency of recurrent throat infection decreased in the tonsillectomy/adenoidectomy and control groups.
What is pharyngitis?
Pharyngitis — commonly known as sore throat — is an inflammation of the pharynx, resulting in a sore throat. Thus, pharyngitis is a symptom, rather than a condition. It is usually caused by viral and/or bacterial infections, such as the common cold and flu (both viral infections) or by infection with the Streptococcus bacterium (strep throat). Pharyngitis can also occur with mononucleosis (aka “mono”), a viral infection.
How is pharyngitis treated?
Viral pharyngitis goes away on its own with salt water gargles, pain relievers and extra fluids to help alleviate the symptoms. Bacterial pharyngitis is treated with antibiotics; and fungal pharyngitis, with antifungal medications. Prompt antibiotic therapy is needed for strep throat because untreated, it can sometimes cause kidney problems and rheumatic fever, which can damage the heart valves. A full assessment in the clinic will guide treatment for other causes.

Can a pharyngitis infection be a viral infection?
Pharyngitis can also occur with mononucleosis (aka “mono”), a viral infection. Fungal pharyngitis occurs in the setting of immunosuppression or chronic steroid and antibiotic use. Sometimes, allergies, such as hay fever or allergic rhinitis, can cause sore throat.
Overview
Diagnosis
A number of scoring systems exist to help with diagnosis; however, their use is controversial due to insufficient accuracy. The modified Centor criteria are a set of five criteria; the total score indicates the probability of a streptococcal infection.
One point is given for each of the criteria:
• Absence of a cough
Signs and symptoms
The typical signs and symptoms of streptococcal pharyngitis are a sore throat, fever of greater than 38 °C (100 °F), tonsillar exudates (pus on the tonsils), and large cervical lymph nodes.
Other symptoms include: headache, nausea and vomiting, abdominal pain, muscle pain, or a scarlatiniform rash or palatal petechiae, the latter being an uncommon but highly specific finding.
Symptoms typically begin one to three days after exposure and last seven to ten days.
Cause
Strep throat is caused by group A β-hemolytic Streptococcus (GAS or S. pyogenes). Humans are the primary natural reservoir for group A streptococcus. Other bacteria such as non–group A β-hemolytic streptococci and fusobacterium may also cause pharyngitis. It is spread by direct, close contact with an infected person; thus crowding, as may be found in the military and schools, increases the rate of transmission. Dried bacteria in dust are not infectious, although moist bact…
Prevention
Tonsillectomy may be a reasonable preventive measure in those with frequent throat infections (more than three a year). However, the benefits are small and episodes typically lessen in time regardless of measures taken. Recurrent episodes of pharyngitis which test positive for GAS may also represent a person who is a chronic carrier of GAS who is getting recurrent viral infections. Treating people who have been exposed but who are without symptoms is not recommended. T…
Treatment
Untreated streptococcal pharyngitis usually resolves within a few days. Treatment with antibiotics shortens the duration of the acute illness by about 16 hours. The primary reason for treatment with antibiotics is to reduce the risk of complications such as rheumatic fever and retropharyngeal abscesses. Antibiotics prevent acute rheumatic fever if given within 9 days of the onset of symptoms.
Prognosis
The symptoms of strep throat usually improve within three to five days, irrespective of treatment. Treatment with antibiotics reduces the risk of complications and transmission; children may return to school 24 hours after antibiotics are administered. The risk of complications in adults is low. In children, acute rheumatic fever is rare in most of the developed world. It is, however, the leading cause of acquired heart disease in India, sub-Saharan Africa, and some parts of Australia.
Complications
Complications arising from streptococcal throat infections include:
• Acute rheumatic fever
• Scarlet fever
• Streptococcal toxic shock syndrome
• Glomerulonephritis
