Strep throat is a bacterial infection of the throat and tonsils caused by Group A Streptococcus bacteria (Streptococcus pyogenes). This contagious infection causes inflammation and throat pain, making swallowing difficult and uncomfortable. In Singapore’s tropical climate, strep throat occurs year-round, affecting both children and adults, though it is most common among school-aged children. The infection spreads through respiratory droplets when infected individuals cough, sneeze, or share food and drinks. Unlike viral throat infections, which may resolve on their own, strep throat typically requires antibiotic treatment to eliminate the bacteria and may help prevent complications.

What is Strep Throat?
Types of Streptococcal Throat Infections
Acute Streptococcal Pharyngitis
This is the typical strep throat presentation, characterised by sudden onset of throat pain, fever, and swollen lymph nodes. The throat appears bright red with white patches or streaks of pus on the tonsils. This type may respond to antibiotic treatment and can resolve with appropriate therapy.
Streptococcal Tonsillitis
When the infection primarily affects the tonsils, they become swollen and covered with white or yellow patches. Patients often experience difficulty swallowing and may have bad breath. The tonsils may become enlarged.
Scarlet Fever
A strep throat infection is accompanied by a characteristic red, sandpaper-like rash that typically starts on the chest and spreads to other parts of the body. The tongue may also appear bright red with a strawberry-like appearance. This occurs when the bacteria produce a specific toxin. This condition can be managed with appropriate antibiotic treatment.
Recurrent Strep Throat
Some individuals experience multiple strep throat infections within a year. This pattern may indicate the need for additional evaluation and potentially different treatment approaches, including consideration of tonsillectomy in some instances.
Causes & Risk Factors
Causes
Strep throat is caused by the Group A Streptococcus bacteria. The bacteria enter the body through the nose or mouth after exposure to infected droplets. Once inside, they multiply in the warm, moist environment of the throat and tonsils. The bacteria produce toxins that can trigger the body’s immune response, leading to inflammation and symptoms. Direct contact with infected surfaces, followed by touching the face, may also transmit the bacteria.
Risk Factors
- Age: Children may have an increased risk due to close contact in schools
- Season: Cases may occur more frequently during cooler months, though cases occur year-round in Singapore
- Close contact: Living with or caring for someone with strep throat
- Crowded environments: Schools, childcare centres, and military barracks
- Weakened immunity: Conditions or medications that suppress immune function
- Previous infections: History of recurrent strep throat may increase susceptibility
- Poor hand hygiene: Inadequate handwashing may facilitate bacterial transmission
- Sharing personal items: Using contaminated utensils, cups, or towels
Signs & Symptoms
Mild Symptoms
- Throat discomfort and scratchiness
- Mild difficulty swallowing
- Low-grade fever
- Slight headache
- Mild fatigue
- Reduced appetite
Moderate Symptoms
- Severe throat pain, especially when swallowing
- High fever
- Swollen, tender lymph nodes in the neck
- Red, swollen tonsils with white patches
- Headache and body aches
- Nausea or vomiting, particularly in children

Strep throat symptoms typically develop after exposure to the bacteria. The onset is usually sudden, with throat pain often being the first and most prominent symptom, distinguishing it from viral infections that develop more gradually.
Experiencing these symptoms?
Consult with an ENT specialist for an accurate diagnosis and appropriate treatment plan.
When to See an ENT Specialist
Seek medical attention promptly if you experience severe throat pain lasting more than 48 hours, especially when accompanied by a fever above 38.5°C. Immediate medical care is essential if you have difficulty breathing, severe difficulty swallowing, drooling, neck stiffness, or signs of dehydration. Children with persistent fever, rash, joint pain, or changes in urine colour need urgent evaluation as these may indicate complications.
During your consultation with an ENT specialist, expect a thorough examination of your throat, neck, and ears. The doctor may review your symptoms, medical history, and perform specific tests to confirm strep throat. Early treatment may help reduce symptoms and reduce the risk of spreading the infection to others. Don’t rely on visual inspection alone – many throat infections look similar, making proper testing essential for accurate diagnosis.
Diagnosis & Testing Methods
- Rapid Antigen Detection Test (RADT): This test can provide results within minutes by detecting strep bacteria antigens from a throat swab. While highly specific, it may miss some infections. A positive result can confirm strep throat, but negative results in symptomatic patients may require additional testing.
- Throat Culture: A standard approach to diagnosing strep throat involves collecting a throat swab and culturing the bacteria in a laboratory. Results typically take 24-48 hours, but can provide a definitive diagnosis and antibiotic-sensitivity information. This test may catch infections that rapid tests might miss.
- Clinical Scoring Systems: ENT specialists may use validated scoring tools, such as the Centor criteria, which evaluate fever, tonsillar exudate, tender lymph nodes, and the absence of cough. These can help determine the likelihood of strep throat and guide testing decisions.
- Blood Tests: In cases of suspected complications or recurrent infections, blood tests may check for inflammatory markers, immune function, and signs of post-streptococcal complications. These aren’t routine, but can provide valuable information in complex cases. This treatment is administered as part of a comprehensive plan supervised by a healthcare professional.
Treatment Options Overview
Antibiotic Therapy
Prescription antibiotics may help eliminate the bacteria causing strep throat. Penicillin V or amoxicillin is commonly prescribed, taken orally for 10 days. Patients allergic to penicillin may receive alternatives like azithromycin or cephalexin. Complete the full course even after symptoms improve, as stopping early may lead to treatment failure or complications.
Symptomatic Relief Medications
While antibiotics address the infection, additional medications can help manage symptoms. Paracetamol or ibuprofen may reduce fever and throat pain. Throat lozenges containing benzocaine can provide temporary numbing relief. An ENT specialist may prescribe more substantial pain relief for severe cases.
Throat Sprays and Gargles
Antiseptic throat sprays may help reduce bacterial load and provide pain relief. Saltwater gargles (half a teaspoon of salt in warm water) performed several times daily can soothe inflammation and help clear debris. Chlorhexidine mouthwash may be recommended for its antimicrobial properties.
Supportive Care Measures
Adequate rest may accelerate recovery and help prevent complications. Staying hydrated with warm liquids like soup or tea can soothe a sore throat and help prevent dehydration. Cool, soft foods may minimise swallowing discomfort. Using a humidifier adds moisture to dry air, which may reduce throat irritation.
Treatment for Recurrent Cases
Patients experiencing multiple strep throat episodes may need extended antibiotic courses or different antibiotic classes. Testing and treating close contacts can help break transmission cycles. Some cases may benefit from monthly prophylactic antibiotics during high-risk periods.
Surgical Interventions
For patients with frequent recurrent strep throat, tonsillectomy may be considered. This surgical removal of the tonsils can reduce the risk of future strep throat episodes. An ENT specialist evaluates each case individually, considering the frequency of infections, their severity, and their impact on quality of life. Individual results and treatment outcomes may vary.
Every patient’s condition is unique.
An ENT specialist can assess your specific situation and recommend the most suitable treatment.
Complications if Left Untreated
Untreated strep throat can lead to complications affecting multiple organ systems. Peritonsillar abscess (quinsy) may develop, causing throat swelling that can obstruct breathing and may require emergency drainage. The infection can spread to surrounding tissues, potentially leading to neck abscesses or lymph node infections that may require surgical intervention.
Rheumatic fever remains a concern, potentially causing heart valve damage, joint problems, and neurological issues. Post-streptococcal glomerulonephritis can affect the kidneys, leading to blood in urine, swelling, and high blood pressure. These complications may occur following the initial infection.
The infection may also spread to the sinuses, causing sinusitis, or to the middle ear, resulting in otitis media. Some patients may develop PANDAS (Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections), experiencing a sudden onset of tics or obsessive-compulsive behaviours. Treatment with appropriate antibiotics can help prevent these complications. This information is provided for educational purposes and should not replace professional medical advice.
Prevention
Preventing the transmission of strep throat requires consistent hygiene practices and awareness. Regular handwashing with soap and water for at least 20 seconds, especially after coughing or sneezing, may help reduce the risk of transmission. Avoid sharing personal items such as utensils, cups, or toothbrushes, particularly during outbreaks in schools or households.
Infected individuals should stay home from work or school for at least 24 hours after starting antibiotics to help prevent the spread of the infection. Cover coughs and sneezes with a tissue or the elbow, and dispose of tissues immediately. Replace toothbrushes after beginning antibiotic treatment to help prevent reinfection.
Maintaining good general health through adequate sleep, balanced nutrition, and stress management can help support immune defences. In households with recurrent infections, simultaneous testing and treatment of all members may be necessary to help eliminate bacterial reservoirs. Regular cleaning and disinfection of frequently touched surfaces can help reduce environmental contamination.

Frequently Asked Questions (FAQ)
How can I tell if my sore throat is strep throat or just a viral infection?
Strep throat may cause sudden, severe throat pain with fever above 38°C, swollen lymph nodes, and white patches on the tonsils. Viral infections often develop gradually, with additional symptoms such as cough, runny nose, and hoarseness, which are less familiar with strep. Accurate diagnosis requires proper testing by a medical professional, as visual examination alone cannot definitively distinguish between bacterial and viral infections.
How long is strep throat contagious, and when can I return to work or school?
Without treatment, strep throat may remain contagious for an extended period. With appropriate antibiotic treatment, contagiousness can be reduced significantly after 24 hours. Patients may return to work or school 24 hours after starting antibiotics, provided their fever has resolved and they feel well enough. Continue taking antibiotics for the full prescribed course to help eliminate bacteria.
Can strep throat go away on its own without antibiotics?
While some cases might eventually resolve without treatment, this approach can carry risks. Untreated strep throat may increase the risk of complications, including rheumatic fever, kidney problems, and abscess formation. Untreated patients may remain contagious longer and experience symptoms for extended periods. Antibiotic treatment aims to reduce symptom duration, help prevent complications, and limit spread to others.
Why do some people get strep throat repeatedly?
Recurrent strep throat may result from incomplete treatment courses, reinfection from close contacts, or being a strep carrier who experiences repeated activation. Some individuals have anatomical factors, such as deep tonsil crypts, that can harbour bacteria. Weakened immunity, exposure to different strep strains, and antibiotic resistance may also contribute. An ENT specialist can evaluate recurrent cases to identify underlying causes and develop targeted prevention strategies.
Is strep throat more serious in adults or children?
While strep throat affects both age groups, children may face higher infection rates due to close school contact. Adults often experience more severe symptoms and longer recovery times. Complications such as peritonsillar abscesses may occur more frequently in adolescents and young adults. Both groups require prompt treatment, though medication dosing and symptom management approaches may differ based on age.
Can I prevent getting strep throat if my family member has it?
While complete prevention cannot be guaranteed, several measures may help reduce transmission risk within households. The infected person should use separate utensils, cups, and towels. Frequent handwashing, especially before meals and after contact with the patient, is important. Disinfect commonly touched surfaces regularly. Some doctors may recommend preventive antibiotics for high-risk family members, though this is not routine practice.
Conclusion
Strep throat requires proper medical evaluation and treatment for recovery and to prevent complications. Unlike viral throat infections, strep throat responds to antibiotic therapy, with patients potentially experiencing improvement within 48 hours of starting treatment. Early diagnosis through appropriate testing allows for targeted treatment that may reduce symptom duration and prevent transmission to others.
Our ENT Specialist combines thorough clinical evaluation with evidence-based treatment to manage both acute and recurrent cases of strep throat. Whether you’re experiencing your first episode or dealing with recurring infections, a professional assessment aims to provide appropriate care for your specific situation.
