Difference Between Scarlet Fever and Strep Throat – Diagnosis and Treatment

Scarlet fever, also known as scarlatina, can occur in some people who have strep throat. Bacteria cause the illness, which features main symptoms such as a sore throat and a bright red rash that often feels rough to the touch.

Strep throat and scarlet fever are linked because the same type of bacteria causes both illnesses.

People with scarlet fever may notice other symptoms such as a high fever, red lines in the folds of the skin, and a red, bumpy tongue.

These signs, along with the sore throat and rash, help health professionals identify and treat the illness. Understanding the warning signs helps people get care and prevent the spread of infection.

Diagnosis

To diagnose a strep infection or scarlet fever, a doctor first checks the throat, tonsils, and tongue for redness or swelling.

The doctor also feels the neck to see if the lymph nodes are larger than normal and looks for a rough-textured rash.

A doctor collects a swab from the back of the throat and tonsils. This sample is used for two main types of tests:

• Rapid Strep Test:
  • Provides quick results, often during the office visit.
  • Detects group A streptococcus bacteria fast.
  • If the test is positive, treatment can begin right away.
• Throat Culture:
  • The doctor orders this if the rapid test is negative but strep is still suspected.
  • Yields results in up to two days.
  • Detects infections that the rapid test may miss.

Both tests play an important role because several illnesses can look similar, but treatments may be different.

How to Manage and Treat Scarlet Fever

Doctors usually prescribe antibiotics to treat scarlet fever. Penicillin is a common option, but they may choose other antibiotics if needed.

The patient should finish the full course of medication, even if they start feeling better before the medicine is gone.

To help relieve fever and throat pain, doctors recommend over-the-counter pain relievers like acetaminophen or ibuprofen. Always check with a doctor for the right dose.

Treatment Option	Purpose
Antibiotics	Fight the infection.
Ibuprofen/Acetaminophen	Reduce fever and ease pain.

Returning to normal activities, such as school, is usually safe after at least 12 hours of antibiotics and once there is no more fever. Following the full treatment plan lowers the risk of problems later on.

Managing Symptoms at Home

Children and adults with scarlet fever benefit from steps that focus on comfort, hydration, and reducing the spread of infection. Extra rest helps the body fight fever and headache.

Keeping the person home from school or work until fever has stopped, and after taking antibiotics for at least 12 hours, helps prevent scarlet fever from spreading to others, since it is contagious.

Drinking plenty of water is important to avoid dehydration, especially if there is vomiting or stomach pain. Cool water, ice chips, and warm broths help keep the throat moist.

For older children and adults, a saltwater gargle can ease a sore throat. Mix 1/4 teaspoon of salt into a cup of warm water and have them swish and spit (do not swallow).

Soothing foods like soft fruits, applesauce, mashed potatoes, yogurt, and scrambled eggs are gentle on a sore throat.

Children may find cold treats like frozen yogurt or fruit pops helpful. Spicy or acidic foods, such as orange juice and peppers, should be avoided since they may make the throat pain worse.

Table: Self-Care for Scarlet Fever

Symptom	Self-Care Tip
Fever/Chills	Rest, keep hydrated
Headache	Quiet, cool environment
Sore Throat	Saltwater gargle, honey*, soft foods
Vomiting/Stomach pain	Sips of water, bland diet, rest
Contagious	Stay home, practice good hygiene

*Do not give honey to infants under 12 months.

Keep the air moist by using a cool-mist humidifier and cleaning it each day to prevent buildup of germs.

Saline sprays help with dryness in the nose and throat. Avoid cigarette smoke or strong smells like paint, incense, or cleaning products, as these may irritate the throat further.

Simple self-care steps reduce discomfort and help children and adults recover more comfortably from scarlet fever.

Getting Ready for Your Visit

Steps You Can Take Before the Appointment

Before meeting with a healthcare provider, prepare information and questions to discuss.

Write down important details to ensure nothing is forgotten during the visit. Keep track of symptoms—such as when they started, how severe they are, and any changes—to help the provider understand the situation better.

Write a list of questions you might want to ask. Some common questions parents and caregivers find helpful include:

• How soon after my child starts treatment will symptoms improve?
• Could my child experience any long-term effects from scarlet fever?
• Are there ways to help relieve itchiness or skin discomfort?
• When is it safe for my child to go back to school?
• How contagious is the illness, and how can we lower the risk for others in the home?
• Are there generic options for prescribed medicine, or alternatives if there is an allergy to penicillin?

Bringing a written list to the appointment makes it easier to remember your concerns. You can also ask about instructions for care at home and when to return if symptoms do not improve.

Items to Bring to Your Appointment:

Item	Why It’s Helpful
Symptom notes	Helps the provider learn about the illness.
Medication/allergy list	Aids in safe, effective treatment.
List of recent illnesses	Provides useful background.
Insurance or ID cards	Saves time during check-in.

Be ready to share any medicines your child is taking and any allergies, especially to antibiotics, as this is important for choosing the right treatment.

What Healthcare Providers May Discuss or Ask About

During your visit, the healthcare provider will likely ask questions to better understand the illness and choose the next steps. Be ready to answer these questions as clearly as possible:

• When did symptoms, such as sore throat or rash, first appear?
• Has your child had a fever? How high did it get, and how long did it last?
• Was there any vomiting, belly pain, loss of appetite, or headache?
• Did your child have trouble swallowing or eating?
• Was your child recently around anyone who had a strep infection or scarlet fever?
• Are there any ongoing health issues or regular medicines that your child takes?
• Does your child have any medication allergies?

By answering these questions, you help the provider make a plan for testing, treatment, and care.

The provider may do a physical exam and could take a quick throat swab for a rapid strep test. Results from this test help decide if antibiotics or other treatments are necessary.

What to Expect During the Appointment:

• The provider will check your child’s throat and skin.
• They may run tests for strep bacteria.
• The provider will advise you about keeping your child home from school and caring for them at home.
• You will likely get guidance on when it is safe to return to normal activities.

Healthcare providers help children and families with scarlet fever and related infections.

They can answer any additional questions you have and provide clear steps to follow after your visit. Bring up any worries or symptoms that have not been discussed.

More Details

Group A Streptococcus causes several different infections, most commonly strep throat and skin infections like impetigo. This bacterial infection can also lead to scarlet fever, which often appears with a red rash and sore throat.

Complications:

• If left untreated, group A strep infections may cause more serious health issues, such as rheumatic fever (which can affect the heart and joints) or glomerulonephritis (a kidney condition).
• Other complications include pneumonia, meningitis, or Reye syndrome, though these are less common.

Possible Complications Table

Complication	Notes
Rheumatic fever	Can damage heart valves
Glomerulonephritis	May lead to kidney problems
Pneumonia	Infection of the lungs
Meningitis	Inflammation of the membranes around the brain
Reye syndrome	Rare, usually in children after viral infections

Risk Factors:

• Children between ages 5 and 15 are most likely to get group A strep infections.
• Being in close contact with someone who has a strep infection can raise the risk of getting sick.
• Crowded places, such as schools or daycares, make it easier for germs to spread.

Strep bacteria can infect the throat or the skin, causing different health problems.
