What is Scarlet Fever?

Scarlet fever is a bacterial infection caused by group A  Streptococcus, that also causes strep throat. It mostly affects children but can affect adults too. It causes red bumpy sandpaper like rashes all over the body with high fever, sore throat, red strawberry like tongue and body pains. Though it can be a very uncomfotable experience, in most cases it can be effectively treated with antibiotics.



Scarlet Fever Causes in Children

Scarlet fever is caused by the same bacteria as strep throat - Group A Streptococcus. It is highly contagious and easily spreads when an infected person sneezes or coughs transmitting bacteria as tiny droplets, through air, surfaces, shared plates, glasses, rarely through food not handled well and sometimes by toughing the sores of the infected person. 



Scarlet Fever Symptoms in Children

It starts out as a high fever with sore throat followed by red bumpy rashes all over the body. Rash is the most obvious sign of scarlet fever:

  • The rash first develops around the neck and chest

  • May spread to back, arms, face and legs 

  • Tiny red dots may appear on elbows, underarms, skin folds and groin area might look brighter red than the rest

  • The tongue might start out with a thick white coat

  • Tongue turns to strawberry like red, swollen with bumps and area around mouth may become pale

  • Roof of mouth may also be covered in red bumps 

  • The throat may be sore, swollen with flared up tonsils, may be covered in white yellow pus dots across throat and tonsils

  • High fever, body aches, chills, headaches, nausea, vomiting, stomach pain and decreased appetite is also common in scarlet fever.

  • Skin peeling starts a week to 10 days after the rash fades, even more so on the fingers and could continue to peel for days to weeks.


Scarlet Fever Complications in Children

Scarlet fever in most cases can be easily treated with a course of antibiotics prescribed by your doctor. In very rare cases, the bacteria spreads to various organs causing complications like:

  • Swollen lymph nodes

  • Abcess in the mouth, around tonsils or brain

  • Pneumonia

  • Rheumatic Fever

  • Septicemia

  • Arthritis

  • Meningitis

  • Ear and Sinus Infections

Scarlet Fever Diagnosis in Children

Scarlet Fever Treatment in Children

Scarlet fever is treated using a full course of antibiotics as prescribed by the doctor based on his diagnosis. In most cases you should start to feel better in a day after starting the course but avoid stepping out until 12 hours or longer post the start of treatment as it is highly contagious.



How to Prevent Scarlet Fever in Children

While there are no vaccinations for scarlet fever, practicing good hygiene is key in preventing the infection.

  • Encourage your child to wash hands with soap for 20 seconds regularly

  • Using sanitizer in case soap or water is not accessible

  • Avoid meeting people who are infected with strep and in case you do, wear a mask and follow good hygienic practices like washing hands, avoid touching surfaces and sharing utensils.
