Strep Throat (Streptococcus pyogenes) | Symptoms, Diagnosis & Treatment

How do you Catch Strep Throat

Strep throat in kids is caused by the bacteria streptococci (strep-tuh-kaak-sai) and is highly contagious. It spreads easily through respiratory droplets when an infected child coughs, sneezes, or shares utensils. Kids who test positive for strep but don’t show symptoms are known as carriers and can still spread the bacteria. If left untreated, strep throat in kids can lead to complications like rheumatic fever, which may affect the heart, joints, and other organs.

Strep Throat incubation period

The incubation period for strep throat in kids is usually 2 to 5 days after being exposed to the bacteria Streptococcus pyogenes. During this time, children may not show symptoms but can still be contagious. Close contact in schools or daycare increases the likelihood of spreading the infection.

Is Strep Throat Contagious ?

Strep throat is indeed contagious and can spread easily from person to person. Here’s a detailed overview based on the search results:

1. Respiratory Droplets:The bacteria Streptococcus pyogenes, which causes strep throat, spreads primarily through respiratory droplets released when an infected person coughs, sneezes, talks, or sings. Others can inhale these droplets or come into contact with surfaces contaminated by them.
2. Direct Contact: Strep throat can also spread through direct contact with an infected person's sores or wounds. Touching items like utensils or cups that have been used by someone with strep throat can also transmit the bacteria.
3. Asymptomatic Carriers: Some individuals may carry the bacteria without showing symptoms. While they are less contagious than symptomatic individuals, they can still spread the infection.

Contagious Period

• Without Treatment: Individuals with untreated strep throat can remain contagious for 2 to 3 weeks after contracting the infection.
• With Antibiotic Treatment: Those who start antibiotic treatment typically stop being contagious within 24 to 48 hours after beginning antibiotics. It’s recommended to stay home from work or school until at least 24 hours after starting treatment and once fever has resolved.

What are the Sign and Symptoms of Strep Throat in Kids ?

1. Sore Throat: Sore throat in children can appear suddenly and feel very severe, causing significant discomfort. Swallowing may become painful and difficult. Unlike other throat infections, it often occurs without coughing.
2. Fever: Fever in kids with strep throat is typically high, often exceeding 101°F (38.3°C). It can cause them to feel fatigued and irritable. This fever usually appears suddenly and signals an active infection.
3. Red and Swollen Tonsils: Red and swollen tonsils are a common sign of strep throat in kids. The tonsils may look inflamed and can have white patches or streaks of pus on them. This swelling can make swallowing painful and may cause discomfort.
4. Swollen Lymph Nodes: Swollen neck lymph nodes are a typical symptom of strep throat in kids. These glands may feel tender, enlarged, and sensitive to touch. This swelling occurs as the body fights off the infection.
5. Painful Swallowing: Difficulty swallowing is a common symptom of strep throat in children. Throat pain often makes swallowing uncomfortable or even painful. This can lead to reduced appetite and discomfort while eating or drinking.
6. Tiny Red Spots on the Roof of the Mouth: Small, red, dot-like spots, known as petechiae, may appear on the roof of a child's mouth during strep throat. These tiny spots are a common indicator of infection. Their presence can help distinguish strep throat from other causes of sore throat.
7. Bright Red Tongue: A bright red tongue, often called "strawberry tongue" can develop during a strep throat infection. The tongue appears swollen and has a bumpy texture. This symptom is commonly associated with strep-related infections like scarlet fever.
8. Headache: Many children with strep throat experience headaches alongside other symptoms like fever and sore throat. The headache can range from mild to severe. It often contributes to overall discomfort and irritability in kids.
9. Body Aches: Children with strep throat often experience general discomfort and body aches. These aches can affect the muscles and joints, making movement painful. It adds to the overall feeling of tiredness and irritability.
10. Rash: In some cases, children may develop a red, rough rash that feels like sandpaper. This rash is a sign of scarlet fever, which can occur with strep throat. It typically starts on the chest and spreads to other parts of the body.
11. Nausea or Vomiting: Younger children with strep throat may show gastrointestinal symptoms like nausea or vomiting. They might also experience abdominal pain along with other throat-related symptoms. These symptoms are often more common in younger children.
12. Fussiness or Irritability: In younger children with strep throat, increased fussiness or irritability is common. They may become more sensitive or upset than usual. This behavior can be a sign of discomfort from the infection.
13. Sleeping More Than Usual: Children with strep throat may experience increased fatigue and sleep more than usual. This is because their body is fighting the infection. Rest helps them recover from the illness.
14. Dehydration Signs: In severe cases, children may refuse to eat or drink because of throat pain. This can lead to signs of dehydration, like a dry mouth or less frequent urination. Dehydration should be addressed promptly to prevent further complications.

Strep Throat without tonsils

1. Reduced Risk: Having your tonsils removed (tonsillectomy) may lower your risk of developing strep throat because the tonsils are often a primary site for bacterial growth. However, it does not eliminate the possibility of infection entirely.
2. Symptoms May Be Milder: Individuals without tonsils may experience milder symptoms if they do contract strep throat, but they can still exhibit many of the same signs as those with tonsils.
3. Infection Location: In people without tonsils, strep throat can still affect other parts of the throat. The infection may present similarly in terms of sore throat and fever, but without swollen tonsils.
4. Continued Susceptibility: The body does not develop immunity to strep bacteria after recovering from an infection, meaning that individuals can get strep throat multiple times throughout their lives, regardless of whether they have their tonsils.

What kind of complications can Strep Throat Cause

Strep throat can lead to several complications in children if left untreated. Here are the primary complications associated with strep throat:

1. Rheumatic Fever : A serious inflammatory condition that can develop after a strep throat infection, particularly in children aged 5 to 15. It can cause painful and inflamed joints, a specific type of rash, and damage to heart valves, leading to long-term heart issues.
2. Poststreptococcal Glomerulonephritis : This condition involves inflammation of the kidneys following a strep infection. It may present with symptoms such as blood in urine, swelling (edema), and high blood pressure. Typically resolves on its own but requires monitoring.
3. Scarlet Fever : A streptococcal infection characterized by a bright red rash that usually starts on the neck and spreads to the rest of the body. Accompanied by sore throat, fever, and a "strawberry tongue." It can lead to further complications if untreated.
4. Peritonsillar Abscess : A collection of pus that forms near the tonsils, often as a result of untreated strep throat. Severe throat pain, difficulty swallowing, and swelling that can obstruct breathing.
5. Sinusitis and Ear Infections : The bacteria can spread to nearby areas such as the sinuses or middle ear. Symptoms may include facial pain (for sinusitis) or ear pain and fluid drainage (for ear infections).
6. Meningitis : Though rare, the bacteria can cause inflammation of the protective membranes covering the brain and spinal cord. Symptoms include severe headache, fever, stiff neck, and sensitivity to light.
7. Bacteremia : The presence of bacteria in the bloodstream can occur if strep bacteria enter circulation. This condition can lead to severe systemic infections and requires immediate medical attention.
8. Toxic Shock Syndrome : A rare but severe condition caused by toxins released by strep bacteria that can lead to organ failure. Symptoms include high fever, low blood pressure, confusion, and widespread rash.
9. Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococci (PANDAS) : A controversial condition where strep infections may trigger neuropsychiatric symptoms in some children. Symptoms include sudden onset of obsessive-compulsive behaviors or tics following a strep infection.

How is Strep Throat Diagnosed

• Rapid Strep Test : A cotton swab is used to collect a sample from the back of the throat. This test can quickly detect the presence of strep bacteria (Group A Streptococcus) within minutes by identifying specific antigens. If positive, it confirms strep throat; if negative but suspicion remains, further testing may be warranted.
• Throat Culture : If the rapid test is negative or if further confirmation is needed, a throat culture may be performed. A swab is taken from the throat and sent to a laboratory to see if strep bacteria grow from the sample. Results from a throat culture can take 1 to 2 days.
• Strep Throat Swabs : Strep throat swabs, such as rapid strep tests, quickly check for group A Streptococcus bacteria and provide results within minutes. Throat cultures take 1-2 days for confirmation if needed. PCR tests can also detect bacterial genetic material from a throat swab.

Strep Throat Treatment 

1. Antibiotic Therapy
   • If a child tests positive for strep throat, a healthcare provider will prescribe antibiotics, typically penicillin or amoxicillin. The standard treatment duration is about 10 days.
   • Most children will start feeling better within 1 to 2 days of starting antibiotics, and they are usually no longer contagious after 24 hours of treatment.
2. Symptomatic Relief
• Hydration: Encourage your child to drink plenty of fluids to stay hydrated. Warm liquids like broth, tea, or hot chocolate can be soothing, while cold treats like popsicles or ice cream may also provide relief.
• Soft Foods: If swallowing is painful, offer soft foods that are easier to eat, such as yogurt, mashed potatoes, or applesauce.
• Saltwater Gargle: For children over age 6 who can gargle safely, mixing half a teaspoon of salt in warm water and gargling several times a day can help soothe a sore throat.
3. Home Care and Hygiene 
• Rest: Ensure your child gets plenty of rest to help their body recover.
• Avoid Spreading Infection: Keep your child at home until they have been on antibiotics for at least 24 hours and are fever-free. Teach them to cover their mouth when coughing or sneezing and encourage frequent handwashing.
• Separate Utensils: Use separate eating utensils and dishes for your child during their illness to prevent spreading the bacteria to other family members.

Strep Throat treatment without Antibiotic

• Rest: Ensure the child gets plenty of rest to help their body fight the infection.
• Hydration: Encourage fluids like water, warm tea, or broths to soothe the throat and stay hydrated.
• Pain Relief: Over-the-counter pain relievers like acetaminophen or ibuprofen can reduce fever and discomfort.
• Saltwater Gargle: For older children, gargling with warm salt water may help reduce throat pain and swelling.
• Honey and Lemon: For children over one year, honey with lemon can soothe a sore throat naturally.

Note : If antibiotics for strep throat aren’t working, it could be due to antibiotic resistance, improper dosage, or a misdiagnosis. Consult a doctor to reassess the treatment plan.

Can strep throat be prevented

• Frequent Handwashing: Encourage regular handwashing with soap and water to remove bacteria.
• Avoid Close Contact: Keep children away from those showing symptoms of strep throat.
• No Sharing: Teach kids not to share personal items like utensils, cups, or toothbrushes.
• Cough/Sneeze Etiquette: Encourage covering the mouth and nose with a tissue or elbow when coughing or sneezing.
